Main Advantages

1. Class B flame retardant protection with high power distribution safety The cable adopts high-standard WDZB Class B flame retardant formula with excellent overall flame retardant performance. It can self-extinguish quickly and resist flame spread in case of fire, effectively stopping fire propagation along cable trays and pipe galleries. Compared with ordinary cables, its fire resistance is greatly improved, lowering risks of electrical fire in low-voltage distribution systems of buildings and factories, and meeting safety power distribution standards for public buildings and industrial projects.
2. LSZH eco-friendly material to eliminate secondary fire hazards The cable uses halogen-free and heavy-metal-free eco-friendly insulation and sheath materials without toxic components. When burning, it generates very little smoke and releases no corrosive or toxic fumes. In fire events, it ensures clear sightlines for personnel evacuation and avoids secondary disasters such as poisoning and equipment corrosion, complying with environmental and fire protection requirements of green buildings and crowded public places.
3. Stable cross-linked insulation, high temperature resistance and long service life It adopts high-performance XLPE (Cross-linked Polyethylene) insulation with dense and stable molecular structure, featuring outstanding high-temperature resistance, oxidation resistance and electrical ageing resistance. It will not easily soften, deform or suffer insulation breakdown under continuous full-load operation. Its weather resistance and voltage stability far exceed ordinary PVC power cables, extending cable service life and greatly reducing later maintenance and replacement costs.
4. Superior sheath protection adapting to complex working conditions The outer sheath is made of high-strength flame-retardant polyolefin with excellent mechanical properties, featuring good compression resistance, tensile strength, wear resistance and impact resistance. It also delivers reliable moisture-proof, waterproof and acid-alkali corrosion resistance. It can operate stably in complex concealed laying environments such as cable trenches, underground direct burial, indoor cable trays and enclosed pipe galleries with strong environmental adaptability.
5. Large current-carrying capacity, low loss and stable power transmission Constructed with finely stranded high-purity oxygen-free copper conductors, it has excellent conductivity, uniform resistance and extremely low transmission loss with sufficient rated current-carrying capacity. It can steadily carry heavy civil and industrial power loads for a long time. It features low temperature rise during operation, stable insulation performance and strong leakage resistance, ensuring continuous and stable operation of building main power distribution and equipment power distribution systems around the clock.

Technical Specifications

Applications

WDZB-YJY LSZH Class B flame-retardant power cable is a high-end general engineering low-voltage distribution cable with multi-core power structure, strong current-carrying capacity and high flame retardant safety grade. It fits multiple construction scenarios including indoor cable tray laying, trunking laying, underground pipe burial, cable trench and enclosed pipe gallery laying. It can run stably in humid, dusty indoor and underground environments with stable temperature range. Widely applied in residential communities, commercial complexes, office buildings, hospitals, schools and other civil buildings, as well as factory plants and municipal supporting projects for floor main power distribution, equipment power supply and public lighting distribution systems. It is the standard supporting cable for low-voltage power distribution projects of modern green buildings.
