BV/BVR Insulated Electrical Wire

Release time:2021-05-15

Copper Core PVC Insulated (Flexible) Wire

A layer of non-conductive material, such as resin, plastic, silicone rubber, PVC, etc., is evenly and airtightly wrapped on the wire to form an insulating layer to prevent accidents caused by leakage, short circuit, electric shock, etc. Get in touch with the outside world. This kind of wire is called an insulated wire.
Commonly used wires are divided into insulated wires and bare wires. The core requires good electrical conductivity, high mechanical strength, uniform texture, smooth surface, no cracks, and good corrosion resistance.

Wires with insulating coatings are called insulated wires. Insulated wire is divided into two types: copper core and aluminum core according to core wire material; divided into single strand and multi-strand according to the number of core strands; divided into single core, dual core, multi-core, etc. according to structure; divided into rubber insulated wire and plastic according to insulation material Insulated wires. The outer protective layer of rubber insulated wires is divided into two types: cotton yarn organization and glass fiber organization.

Rubber insulated wire: The structure of rubber insulated wire is to wrap a layer of rubber as an insulating layer on the core, and then a layer of yarn or glass fiber braid as a protective layer. Mainly used for indoor wiring, long-term working temperature does not exceed 60 ℃. Rubber insulated wires with AC voltage lower than 250V can only be used for lighting circuits.
Plastic insulated wire: This kind of wire uses polyvinyl chloride as an insulating coating, also known as plastic wire. Plastic wire has the characteristics of oil resistance, acid resistance, corrosion resistance, moisture resistance, mildew resistance, etc. It is often used in indoor lighting circuits below 500V and can be directly laid on hollow boards or walls.
