Instructions For Use Of Refractory Wires?

Aug 04, 2022

BV wire is commonly known as plastic copper wire. Generally, it is mainly used for single-core hard electrical conductors without sheathing wires and cables. It has the characteristics of strong acid and alkali resistance, wear resistance, waterproof, and mildew removal. It is widely used in households.

First, the type of BV line


ZC-BV: Cable copper wire PVC insulated flame retardant cable: The insulating material is added with a halogen-free flame retardant, and it will not catch fire when it leaves.


ZC-BV: The resistance BV line is divided into four levels: A, B, C, and D. Among them, the A type is good, and so on. It is commonly used as ZC-BV.


N-BV: Cable copper wire PVC insulated fire-resistant wire: It can start normally under the premise of normal fire.


2. Model specifications of BV line


BV lines generally use the cross-sectional area of the core metal conductor of the cable sheath to distinguish the specifications and models. (For example, the diameter of the copper wire section of a 4 square meter BV wire cable is 2.25mm, according to the annular area formula S=π*r*r=3.976mm²)


Common 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, 120 square meters, 150 square meters, 185 square meters, 240 square meters, etc.


Third, the usefulness of BV line


BV line has the characteristics of strong acid and alkali resistance, wear resistance, waterproof, mildew removal, etc. It is generally mainly used for single-core hard electrical conductor unsheathed cables, suitable for power systems with AC current of 450/750V and below, daily high-power electrical appliances, instrument panels and wires and cables used in communication products.
