Environmentally friendly, low-smoke, halogen-free, fire-resistant wire

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

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.
WDZN-BYJ

WDZN-BYJ

WDZN-BYJ stands for a wire that is cross-linked polyethylene insulated (copper core), halogen-free, low-smoke, flame-retardant, and fire-resistant. An electromagnetic wire is an insulated conductor that, when energized, generates a magnetic field or induces an electric current in a magnetic field. It is primarily used in motor windings, transformer windings, and other related electromagnetic devices. Its conductors are mainly made of copper wire and should have a thin insulation layer as well as excellent electrical and mechanical properties, along with resistance to heat, moisture, and solvents. By selecting different insulating materials, wires can achieve varying performance characteristics.
WDZ-BYJ Environmentally Friendly Low-Halogen, Smoke-Free, and Fire-Resistant Wire

WDZ-BYJ Environmentally Friendly Low-Halogen, Smoke-Free, and Fire-Resistant Wire

The cable model WDZ-BYJ stands for low-smoke, halogen-free wire. Low-smoke, halogen-free refers to a classification of materials used for wire and cable jacketing in the wire and cable industry. Low-smoke, halogen-free wire jackets are composed of thermoplastic or thermosetting materials that produce minimal smoke when heated and do not contain halogens themselves. The reference standard for low-smoke, halogen-free wires is JB/T 10491-2004. Common models include WDZ-BYJ and WDZ-RYJ, and many domestic manufacturers already have the production capacity to meet this demand. DW: "Low-smoke, halogen-free" means that the toxic fumes produced by the insulation and protective layer materials when burned are below the required levels, making these cables suitable for power distribution in large public spaces (such as major shopping malls). The jacketing material of network cables is typically made from polyethylene, polyvinyl chloride, or thermoplastic polyurethane. If such chlorine-containing plastics catch fire, they will release toxic hydrogen chloride gas, which can turn into hydrochloric acid upon contact with water. Low-smoke, halogen-free materials significantly reduce the emission of toxic and corrosive gases during combustion. Characteristics of low-smoke, halogen-free wires: 1. Non-toxic—containing no harmful substances whatsoever. 2. Long service life—resistant to aging, with a lifespan exceeding 100 years. 3. High temperature resistance—operating at temperatures up to 150 degrees Celsius. 4. Flame retardant—achieved through irradiation crosslinking technology, giving the wires flame-retardant properties. 5. Compliance with environmental standards—meeting both EU and Japanese environmental standards. 6. Low smoke—when burned, the wires emit only a faint mist of water vapor, with visibility exceeding 60 meters.
