what is electrical cable and its types?

There are various types of wires, which can be divided into many types according to different uses. Compared with wires for other purposes such as engineering, household wires have relatively lower functional requirements. Specifically, household wires are classified as follows.

Hard wire: professionally called BV wire, mainly used for power supply, lighting, sockets, air-conditioning, and suitable for cables and wires for power plants, household appliances, meters and telecommunications 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.

Flexible wire: professionally called BVR wire, 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 carrying capacity than hard wire.
