1. Hard wire
Professionally known as BV wire, it is mainly used for power supply, lighting, sockets, air-conditioning, and it is suitable for cables and wires for power plants, household appliances, meters and telecommunication equipment with AC voltage of 450/750V and below. Hard wire has a certain degree of hardness, which is more convenient in terms of bending and straightening.

2. Flexible cord
Professionally known as BVR wire, it is suitable for cables and wires used in power plants, household appliances, meters and telecommunication equipment with AC voltage of 450/750V and below, such as distribution boxes. Flexible wire is more complicated to manufacture than hard wire, and high-frequency circuit flexible wire has a larger current carrying capacity than hard wire.

3. Hard and soft wires (weak wires)
It is composed of a single and several copper core wires, and generally refers to network cables, wires and cables with relatively low voltage.
