Complete Specification Series, Customizable Core Quantity & Cross-section
We supply single core BV/BVR wires, 2-5 core RVV flexible cables and 3+1/4+1 core YJV power cables. Cross-section options from 1.5mm² to 300mm² are available. Custom core numbers, cable lengths and flame retardant/halogen-free low smoke grades are supported to match residential, factory and power station projects.
Strict Factory Testing, Meet International Safety Standards
Every batch undergoes resistance, insulation withstand voltage, flame retardant and tensile tests before delivery. Products comply with GB, IEC and CE standards. Each cable roll is printed with clear specification marks, with complete inspection reports provided for engineering bidding and acceptance.
Multiple Laying Forms, Flexible Construction & Wide Application
Small BV/RVV wires are lightweight for indoor wall wiring and equipment control circuits. Large YJV armored cables fit underground, overhead and pipe laying. Wooden reel packaging for large cables avoids winding damage during transportation, cutting on-site wiring construction time by over 40%.

| Product Uses |
◉ Residential & Commercial Building Decoration: BV single core wires for indoor wall concealed wiring of household lighting, sockets and air conditioners; RVV flexible cables for elevator, monitoring and equipment control circuits.
◉ Factory Workshop Power Distribution: YJV multi-core power cables supply main power for production equipment, supporting long-distance power transmission between workshop distribution cabinets and machines.
◉ Municipal & Road Engineering: Armored buried cables for urban street lighting, traffic signal power supply and municipal pipeline laying, resisting underground extrusion and corrosion.
◉ New Energy & Power Station Projects: Large-section XLPE power cables for photovoltaic, wind power station grid connection, with high temperature resistance and stable high-current transmission performance.
◉ Construction Site Temporary Power Supply: RVV flexible rubber cables for construction machinery, welding machines and temporary lighting, good bending resistance for frequent moving construction equipment.
| Product Operate Guide |
Calculate required cable cross-section according to total load current before laying. Match flame retardant grade for fire protection areas. Avoid sharp metal extrusion during wiring. For underground laying, select armored cable and add protective pipe. Download full English wiring & laying PDF for construction specification details.
| FAQ |
Q: What is the difference between BV wire and RVV cable?
A: BV is single solid hard wire for fixed indoor wall wiring, low cost and stable layout. RVV is multi-core flexible cable with multiple fine copper strands, suitable for movable equipment, monitoring and control circuits with frequent bending.
Q: Can YJV armored cables be buried directly underground?
A: Yes. Steel tape armored structure resists soil extrusion and rodent bite. We suggest adding HDPE protective pipe in harsh corrosive soil to extend service life further.
Q: Do you provide CE certification for export projects?
A: All cables pass IEC standard testing, CE certification and full test reports can be provided. We also support low smoke zero halogen halogen-free customized cables for overseas high-rise fire protection projects.
Q: What color options are available for BV household wires?
A: We supply standard red, blue, yellow-green, yellow and green color wires to distinguish live wire, neutral wire and earth wire. Custom special sheath colors are acceptable for large engineering orders to meet customer wiring marking demands.
