Main Advantages

1. Integrated flame retardancy and fire resistance for reliable emergency power supply The cable features high-standard Class B flame retardancy and fire resistance as WDZBN. Under exposure to open flame and high temperature, it maintains circuit integrity without short circuit or breakdown, sustaining normal power supply for a period during fire accidents. It effectively ensures uninterrupted operation of Class I and Class II fire loads such as fire pumps, smoke exhaust systems and emergency lighting, greatly improving the self-rescue capability of buildings and meeting strict fire acceptance standards for high-end constructions.
2. Low-smoke zero-halogen and eco-friendly to avoid secondary fire disasters The whole cable adopts low-smoke zero-halogen, heavy-metal-free eco-friendly insulation and sheath materials without toxic halogen components. In case of combustion, it produces minimal smoke and releases no corrosive or highly toxic fumes, keeping evacuation passages visible and preventing personnel poisoning, airway burns and equipment corrosion. It is suitable for densely populated public buildings and key fire protection projects.
3. Stable cross-linked insulation, excellent temperature resistance and long service life It adopts XLPE (cross-linked polyethylene) insulation with highly stable molecular structure, delivering outstanding high-temperature resistance, oxidation resistance and anti-ageing performance. It is not prone to thermal deformation or insulation failure under continuous full-load operation, and withstands long-term power frequency voltage surges. Its anti-ageing property far outperforms ordinary PVC cables, extending service life and reducing renovation and maintenance costs in later project stages.
4. Robust sheath protection for complex laying conditions The outer sheath is made of high-strength polyolefin material with compact structure, featuring excellent compression resistance, tensile strength and mechanical damage resistance. It also has good moisture-proof, waterproof and acid & alkali corrosion resistance, adapting to humid, enclosed and dusty environments such as cable trenches, underground direct burial, indoor cable trays and pipe galleries with wide environmental adaptability.
5. Large current-carrying capacity and low power loss for stable power distribution Constructed with finely stranded oxygen-free copper conductors, it offers excellent conductivity, uniform resistance and low transmission loss with sufficient rated current-carrying capacity. It can steadily carry heavy industrial and civil power loads for a long time with low temperature rise during operation and stable insulation voltage resistance, guaranteeing safe, continuous and reliable operation of building power and public distribution systems around the clock.

Technical Specifications

Applications

WDZBN-YJY low-smoke zero-halogen flame-retardant fire-resistant power cable is an engineering-grade low-voltage power distribution cable with multi-core symmetrical structure, strong current-carrying capacity and high fire protection grade. It is applicable to various construction scenarios including indoor cable tray laying, trunking laying, cable trench laying and underground conduit burial, and can operate stably in humid, enclosed and dusty indoor and underground conditions. Widely used in high-end residential communities, commercial complexes, office buildings, hospitals, schools, rail transit supporting projects and industrial plants with stringent requirements for fire prevention, environmental protection and safety. It is mainly used for equipment power distribution, floor main power distribution, fire power systems and main power distribution lines in public areas, serving as the preferred mainstream cable for low-voltage power distribution projects of modern green fire-resistant buildings.
