WDZ-YJY Product Overview WDZ-YJY is a widely used unarmored low-voltage fixed-lay power cable with a rated voltage of 0.6/1kV. It features a fully low-smoke, halogen-free, flame-retardant structure and is specifically designed for conventional main power distribution circuits in green buildings, municipal auxiliary facilities, and general industrial plants. As a general-purpose trunk cable, it differs from the fire-resistant WDZN-YJY and high-flame-retardant WDZB-YJY products

YJLV22 is an economical armored aluminum power cable designed according to GB/T12706 and the harmonized IEC 60502 international standards. It consists of high-purity aluminum stranded conductors, cross-linked polyethylene insulation, a PVC inner lining, overlapping double-layer steel tape armor, and a weather-resistant PVC outer sheath. Unlike copper-based YJV22 and AA8000 alloy YJLHV22 armored cables, YJLV22 uses conventional high-purity electrical aluminum, significantly

YJLHV22 (8.7/15kV) is a medium-voltage (MV) power cable designed specifically for 10kV distribution networks. It features 8000 series aluminum alloy conductors, cross-linked polyethylene (XLPE) insulation, copper tape shielding, galvanized steel tape armor, and a low-smoke halogen-free (LSZH) outer sheath. Rated at 8.7/15kV (Um=17.5kV), it is designed for applications such as urban power grids, industrial parks, critical public utilities, and renewable energy projects,

ZC-VV22 is a Class C flame-retardant steel-tape armored low-voltage power cable suitable for AC 50Hz, 0.6/1kV three-phase power distribution systems. It is an upgraded version of the VV series, integrating flame retardancy, mechanical armor, and environmental friendliness. Compared to ordinary VV cables (unarmored) and ZR-VV cables (flame-retardant only), ZC-VV22 features double-layer steel tape armor and upgraded flame-retardant PVC material, resulting in stronger compressiv

The YJLHV22 low-voltage power cable is an independently developed upgraded high-performance transmission cable, conforming to international IEC standards and mainstream global power engineering design specifications, with a rated voltage of 0.6/1kV. This cable uses high-purity AA8000 series tightly stranded aluminum alloy conductors, high-temperature resistant cross-linked polyethylene (XLPE) insulation, a double-layer steel tape armor structure, and a weather-resistant and

NH-VV is a fire-resistant low-voltage power cable with a rated voltage of 0.6/1kV. It consists of a solid, tightly packed copper conductor, a fire-resistant special PVC insulation layer, environmentally friendly filler materials, and an integrated PVC outer sheath. NH represents its fire-resistant properties, ensuring continuous power supply for a certain period even in open flame environments. Unlike the flame-retardant ZR-VV cable, which only suppresses flame spread, NH-VV

WDZ-KYJRP is a low-smoke halogen-free shielded control cable rated at 0.45/0.75kV, specifically developed for signal transmission, instrument interconnection, and PLC/DCS cabinet control cabling in fire-sensitive industrial and municipal engineering applications. Detailed model designation: WDZ: Low-smoke halogen-free; insulation, filler, and outer sheath are all made of halogen-free environmentally friendly polymers, free of halogen-containing PVC materials; K: Control cable

WDZN-YJY Low-Smoke Halogen-Free Fire-Resistant Power Cable WDZN-YJY is a low-smoke halogen-free fire-resistant power cable with a rated voltage of 0.6/1kV. It is specifically developed for emergency critical power supply circuits in Class I fire-resistant buildings and important infrastructure, and can maintain continuous power supply for the specified duration of a fire in flame-prone environments.
