NH-BV

Introduction: It boasts excellent thermal and mechanical properties, outstanding electrical performance, and superior resistance to chemical corrosion. At the same time, it features a simple structure, lightweight design, and is not constrained by deployment limitations due to height differences. It is widely used in urban power grids.

NH-BV

NH-BV Wire: As its name suggests, the copper-core polyvinyl chloride insulated fire-resistant wire adds an extra layer of fire-resistant material on top of the BV wire. NH-DV wires are often used in environments where fires are highly likely to occur or in locations with particularly stringent fire safety requirements. The fire-resistant material used in NH-BV wires is made from glass fiber braided fluoromica tape, processed through a special manufacturing technique. Its key features include high-temperature resistance, excellent insulation, fire retardancy, and corrosion resistance. Typically, the fire-resistant layer is wrapped around the surface of the conductor. Depending on the specific fire-resistance requirements, the fire-resistant layer can be either single-layer or double-layer; naturally, the fire-resistant performance will vary accordingly based on the type of fire-resistant layer used.
