450/750V BVR Wire & Cable
Applications
Due to its flexibility and fatigue resistance, BVR wires are particularly suitable for the following scenarios:
- Mechanical equipment
BVR wires are often used for electrical connections in mechanical equipment and can withstand the vibration and movement of the equipment.
- emporary electricity usage
In temporary power supply scenarios such as construction sites and exhibition venues, BVR wires are widely used due to their convenient installation and good flexibility.
- Complex wiring scenarios
In situations where complex wiring is required, such as ceiling and wall wiring in home decoration, BVR wires can adapt well due to their good flexibility.
- Mobile devices
BVR wires are suitable for devices that need to be moved frequently, such as stage lighting and sound equipment.
Features
Compared with BV wires, BVR wires have the following characteristics:
- Flexibility
The multi-strand twisted conductors of BVR wires make them flexible, capable of withstanding frequent bending and movement, and suitable for complex wiring scenarios.
- Ease of installation
Due to the good flexibility, light weight, easy laying and installation of BVR wires, they are particularly suitable for complex wiring scenarios.
- Fatigue resistance
The multi-strand twisted conductors of BVR wires give them high fatigue resistance, enabling them to withstand frequent bending and movement without easily breaking.
Construction
| Conductor |
The conductor of the BVR wire is made by twisting together multiple strands of fine copper wire. This multi-strand twisted structure endows BVR wires with good flexibility, enabling them to withstand frequent bending and movement, and making them suitable for applications that require flexible wiring. |
| Insulation |
The insulation layer of BVR wires is also made of polyvinyl chloride (PVC) material, which has excellent insulation performance, heat resistance and chemical corrosion resistance. The thickness of the insulation layer is determined by the specifications and standard requirements of the wire, usually ranging from 0.6mm to 1.2mm. |
