Hard wire: also known as BV wire, mainly used for power supply, lighting, sockets and air conditioning. Its AC voltage application range is 450/750V and below, mainly used in power plants, household appliances, instruments and telecommunications equipment. Hard wire has a certain hardness, easy to bend and straighten.

Flexible wire: also known as BVR wire, suitable for power plants, household appliances, meters and telecommunications equipment with AC voltage of 450/750V and below. Flexible wire production is relatively complicated, but its high frequency circuit carries more current than hard wire.

Hard and flexible wire (weak wire) : mainly composed of single or multiple copper core wires, usually refers to low-voltage wire and cable such as network cables.
