When an importer searches for a 10mm² BV cable supplier in China, the first question is usually price.
But for a serious electrical project, price is only one part of the purchase.
A 10mm² BV cable quotation should also be checked against the conductor construction, copper resistance, PVC insulation, voltage rating, manufacturing standard, packaging, quantity and destination-market requirements.
This guide is written for importers, electrical distributors, contractors and project buyers who are considering purchasing 10mm² BV cable from a Chinese manufacturer.
What Is 10mm² BV Cable?
10mm² BV cable is a single-core copper building wire with PVC insulation. In the common 60227 IEC 01 / GB/T 5023.3 configuration, it is designed for fixed electrical installations and is commonly specified at 450/750V.
The “10mm²” refers to the nominal cross-sectional area of the copper conductor.
It does not mean that the finished cable has a 10mm outside diameter.
The finished diameter depends on the conductor construction and insulation thickness.
For a typical 10mm² solid copper configuration, the conductor is approximately 3.57–3.58mm in diameter, while the completed insulated wire is larger because of the PVC insulation.
For buyers comparing different Chinese factories, this distinction is important.
A supplier quotation should identify the actual conductor construction rather than simply saying “10mm² copper cable.”
10mm² BV Cable Technical Specifications
A typical 10mm² BV building-wire specification may include:
| Specification | Typical requirement |
|---|---|
| Product | 10mm² BV building wire |
| Conductor | Copper |
| Nominal cross-section | 10mm² |
| Conductor construction | Class 1 solid, or specified alternative |
| Insulation | PVC |
| Rated voltage | 450/750V |
| Maximum DC resistance at 20°C | About 1.83 Ω/km for the referenced configuration |
| Operating temperature | Up to 70°C for standard PVC |
| Application | Fixed electrical installation |
| Standard | Applicable IEC / GB/T specification |
| Packaging | Coil, roll or drum |
The exact specification should be confirmed with the manufacturer and matched to the buyer’s required standard and destination market. The Author 88 product information currently lists 10mm² BV with 1.83 Ω/km maximum DC resistance at 20°C.
For buyers who want to understand how resistance relates to different wire sizes, the existing guide BV Wire Ampacity: How to Choose the Correct Cross-Section for Your Application is useful.
Why Choose 10mm² BV Instead of a Smaller Size?
10mm² provides a larger copper conductor cross-section than 1.5mm², 2.5mm², 4mm² and 6mm².
However, that does not mean 10mm² should automatically replace a smaller conductor.
The correct conductor size depends on the electrical design.
Factors include:
- Required current
- Installation method
- Cable length
- Ambient temperature
- Number of loaded conductors
- Voltage drop
- Protective-device settings
- Applicable electrical regulations
For this reason, a buyer should not tell a manufacturer:
“10mm² is safer, so please quote 10mm².”
Instead, the buyer should provide the required specification from the project.
The manufacturer’s role is then to supply the specified product.
10mm² BV Cable for House Wiring
10mm² BV can be used in certain fixed building-wire applications where the electrical design calls for this conductor size.
Potential applications include:
- Building distribution circuits
- Larger power circuits
- Electrical panels
- Conduit installations
- Trunking
- Commercial buildings
- Industrial fixed wiring
- Residential electrical distribution
The actual application must comply with the electrical regulations applicable to the installation.
For house-wiring buyers, our existing article PVC Building Wire for House Wiring | 10mm² BV Cable Supply provides a more product-specific reference for this size.
Is 10mm² BV Solid or Stranded?
This is one of the most important questions when buying 10mm² BV cable.
A standard BV configuration is commonly associated with a solid Class 1 copper conductor.
However, a buyer should not assume that every manufacturer uses exactly the same conductor construction simply because the product is called “BV.”
The supplier’s technical datasheet should identify the conductor class.
For example:
Solid Class 1
One copper conductor forms the conductor.
Stranded Class 2
Several copper wires form the conductor.
These constructions behave differently during installation.
A solid 10mm² conductor can be relatively stiff, particularly when it has to be routed through a conduit containing several bends.
A stranded rigid construction can provide different handling characteristics.
Our existing article BV Wire vs H07V-U: What Is the Difference and Which One Should You Buy? discusses this issue in more detail, including the specific handling considerations for 10mm² wire.
10mm² BV vs H07V-U
International buyers may see both BV and H07V-U in supplier catalogues.
They should not automatically treat the two product names as identical.
BV is commonly associated with Chinese standards and product designations, while H07V-U is a European harmonized designation for a single-core PVC-insulated solid copper wire.
The important point for a buyer is the standard and conductor construction, not simply the name printed in the product title.
If your customer specifies H07V-U, quote H07V-U according to the required standard.
If the project specifies BV / 60227 IEC 01, quote that specification.
For a detailed comparison, see:
BV Wire vs H07V-U: What Is the Difference and Which One Should You Buy?
What Does 450/750V Mean?
Many 10mm² BV products are specified at 450/750V.
The two numbers are not simply two different maximum voltages.
They represent the rated voltage designation:
U₀/U = 450/750V
Where:
- U₀ is the rated voltage between conductor and earth
- U is the rated voltage between conductors
Our existing What Is 450/750V Electrical Wire and Where Is It Used? article explains the designation and typical fixed-installation applications in greater detail.
When requesting a quotation, specify the required voltage instead of assuming that every PVC building wire has the same rating.
10mm² BV Cable and Copper Resistance
Copper resistance is an important specification when comparing suppliers.
For the referenced 10mm² configuration, the maximum DC resistance at 20°C is approximately:
1.83 Ω/km
This number gives buyers a useful way to compare technically equivalent products.
For example, if two suppliers quote 10mm² copper wire but their stated conductor resistance is significantly different, the buyer should ask why.
Possible reasons could include:
- Different conductor standards
- Different conductor constructions
- Different manufacturing tolerances
- Different technical specifications
- Incorrect quotation information
A cheap price should never be evaluated separately from the technical specification.
Our existing BV Wire Ampacity: How to Choose the Correct Cross-Section for Your Application article also explains why conductor resistance is useful when comparing suppliers.
PVC Insulation for 10mm² BV
The copper conductor is only one part of the product.
The PVC insulation determines much of the finished cable’s physical protection and electrical insulation characteristics.
When purchasing 10mm² BV, buyers should confirm:
- PVC compound
- Nominal insulation thickness
- Rated temperature
- Voltage rating
- Color
- Printing
- Applicable standard
- Flame-performance requirements if applicable
Standard PVC should not automatically be assumed to have special properties such as LSZH or enhanced fire performance.
If a project requires a special insulation compound, it should be written directly into the RFQ.
For a broader discussion, see PVC Insulation vs Other Cable Insulation Materials: What Buyers Should Know.
10mm² BV Cable Packaging
Packaging becomes more important as the order quantity increases.
A factory may offer:
- 100m coils
- 500m coils
- 1,000m drums
- Wooden reels
- Export cartons
- Customized packaging
The best packaging depends on how the buyer intends to use or resell the product.
For example, an electrical distributor may prefer smaller coils because the wire will be sold to contractors.
A large construction project may prefer longer lengths or drums to reduce handling.
Packaging can also affect container utilization.
A lower price per meter does not necessarily result in a lower delivered cost if the packaging takes significantly more space.
How Much Does 10mm² BV Cable Cost in China?
There is no single fixed price for 10mm² BV cable.
The price can change with:
- Copper market price
- Conductor weight
- PVC material
- Standard
- Certification
- Quantity
- Packaging
- OEM printing
- Inspection
- Incoterm
- Destination
For large orders, copper price fluctuations can have a noticeable effect on the final quotation.
Our existing How Much Does BV Wire Cost in China? A Buyer’s Guide explains why buyers should compare quotations based on the complete specification rather than simply looking at the price per meter.
How to Request a 10mm² BV Cable Quotation
Instead of sending:
Please quote 10mm² BV cable.
Send the factory a complete specification.
For example:
Product: 10mm² BV / 60227 IEC 01
Conductor: Copper
Conductor class: Class 1 solid
Insulation: PVC
Voltage: 450/750V
Color: Blue
Quantity: 20,000 meters
Packing: 500m coils
Destination: [Country / Port]
Certification: [Required certification]
Trade term: FOB or CIF
Then ask the manufacturer to provide:
- Unit price
- MOQ
- Technical datasheet
- Maximum DC resistance
- Insulation thickness
- Packing details
- Gross and net weight
- Production lead time
- Test report
- Certification
- Sample availability
- Price validity
This makes the quotation much easier to compare with another factory.
10mm² BV Cable MOQ
MOQ depends on the factory, product specification, color, packaging and whether the order is standard or customized.
A buyer should therefore avoid assuming that there is one universal MOQ for 10mm² BV.
Ask the manufacturer for:
Standard-product MOQ
and, separately:
Customized/OEM MOQ
These can be very different.
If you are purchasing several sizes at the same time, also ask whether the supplier accepts mixed-size orders.
For example:
- 1.5mm²
- 2.5mm²
- 4mm²
- 6mm²
- 10mm²
A mixed-size container can sometimes be more practical for distributors than ordering only one size.
What Should an Importer Check Before Placing a Large Order?
Before paying a deposit, check the actual specification rather than relying only on the product title.
A practical checklist is:
Product
Confirm that the product is actually 10mm² copper PVC building wire.
Conductor
Confirm solid or stranded construction and conductor class.
Standard
Confirm the exact applicable standard.
Voltage
Confirm the rated voltage.
Resistance
Request the maximum DC resistance at 20°C.
Insulation
Confirm material and thickness.
Color
Make sure the color matches the market or project requirement.
Printing
Approve the wire marking before mass production.
Packaging
Confirm the length per coil or drum.
Documentation
Confirm test reports and certification requirements.
Shipment
Confirm Incoterm, port, lead time and shipping arrangement.
This process reduces the possibility of receiving a product that technically looks similar but does not match the original quotation.
Why Direct Communication With the Manufacturer Matters
When ordering 10mm² BV cable in bulk, small specification differences can become significant across thousands of meters.
Direct communication allows the buyer to discuss:
- Conductor construction
- Copper specification
- PVC compound
- Color
- Printing
- Coil length
- Drum size
- OEM packaging
- Certification
- Production schedule

FAQ: 10mm² BV Cable
Can 10mm² BV cable be used for house wiring?
It can be used for suitable fixed-wiring circuits when the electrical design specifies this conductor size. The correct size depends on current, installation conditions, voltage drop and local electrical requirements.
Is 10mm² BV always solid copper?
The commonly referenced BV configuration is associated with a solid Class 1 copper conductor, but buyers should confirm the actual conductor construction on the supplier’s technical datasheet rather than relying only on the product name.
Is 10mm² BV the same as H07V-U?
They are related types of single-core PVC-insulated building wire, but the designation and applicable standards are different. If a project specifies H07V-U, the buyer should request the H07V-U specification rather than assuming that a BV label is automatically acceptable.
Why is 10mm² BV harder to bend?
A 10mm² solid copper conductor contains substantially more copper than smaller building-wire sizes and is physically more rigid. This becomes noticeable when routing the wire through conduits with multiple bends.
Would stranded wire be easier to install than 10mm² solid BV?
It can be, depending on the installation. A stranded rigid conductor may provide different handling characteristics, particularly where the route contains bends. The project specification should determine which conductor construction is permitted.
What is the resistance of 10mm² copper wire?
For the referenced 10mm² configuration, the maximum DC resistance at 20°C is about 1.83 Ω/km. The exact requirement should be confirmed against the applicable standard and supplier datasheet.
Can 10mm² BV be supplied in different colors?
Yes, manufacturers can generally produce different insulation colors, subject to their available production range and order requirements. The buyer should specify the required colors before quotation.
Can a factory print my company name on 10mm² BV cable?
OEM or private-label printing may be available. Ask the factory about minimum quantities, printing method, artwork approval and any additional cost.
What is the best packaging for a 10mm² BV cable wholesale order?
There is no single answer. Distributors may prefer coils, while large construction projects may prefer longer lengths or drums. The correct packaging depends on how the product will be transported, stored and installed.
How should I compare two Chinese 10mm² BV cable suppliers?
Put both quotations on the same specification first: conductor class, cross-section, standard, voltage, PVC insulation, resistance, color, quantity, packaging, certification and Incoterm. Only then should you compare the price.
10mm² BV Cable Supplier China for Wholesale Orders
For a wholesale buyer, the key is not simply finding a factory that lists “10mm² BV cable.”
The important question is whether the manufacturer can consistently supply the exact specification required by your project or market.
Before requesting a final quotation, clearly define:
10mm² + copper conductor + conductor class + PVC insulation + voltage + standard + color + quantity + packaging + destination.
If you are comparing 10mm² BV with H07V-U, read BV Wire vs H07V-U: What Is the Difference and Which One Should You Buy?.
If your project includes several building-wire sizes, the What Is 60227 IEC 01 Cable? Specifications, Applications and Buying Guide article can also help you prepare a more complete RFQ.
For buyers ready to compare specifications and request a quotation, providing the complete technical requirements at the beginning will save time for both the importer and the Chinese manufacturer.
