BV wire is commonly known as plastic copper wire. It is generally used for single-core hard conductor wire and cable without sheath. It has the characteristics of strong acid and alkali resistance, wear resistance, waterproof, and mildew removal. It is widely used (industrial equipment, building wiring, construction, etc.) decoration, power cabinet, switch cabinet, power box, lighting wiring).
The type, model specification, and main purpose of the BV line.
1. The type of BV line
ZR-BV: cable copper wire PVC insulated flame retardant cable: the insulating material is added with flame retardant, and it will not catch fire when it is used away.
ZR-BV flame retardant level: Flame retardant BV wire is divided into three levels: A, B, and C. Among them, class A is the best, and so on, and it is commonly used as ZR-BV.
NH-BV: cable copper wire PVC insulated fire-resistant wire: it can start normally under the premise of normal fire.
2. Model specification of BV line
The BV line generally uses the cross-sectional area of the core metal conductor of the cable sheath to distinguish the specification and model. (For example, the cross-sectional aperture of the copper wire of a 4 square meter BV line cable is 2.25mm, based on the circular area formula S=π*r*r=3.976mm2)
Commonly used bv line model specifications:
0.75 square meters, 1 square meters, 1.5 square meters, 2.5 square meters, 4 square meters, 6 square meters, 10 square meters, 16 square meters, 25 square meters, 35 square meters, 50 square meters, 70 square meters, 95 square meters meters, 120 square meters, 150 square meters, 185 square meters, 240 square meters, etc.
