Product Overview YJVR is a low-voltage flexible power cable designed for fixed installations requiring superior bending performance; it is suitable for AC power transmission and distribution systems with a rated voltage of 0.6/1 kV. The "R" in the model designation denotes flexibility (soft construction). Its primary distinction from rigid YJV cables lies in the use of Class 5 stranded, fine-filament annealed copper conductors—compliant with IEC 60228 and GB/T 3956 standards

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

YJV cables are manufactured in strict accordance with the global industrial standards GB/T12706 and IEC 60502. They are widely recognized general-purpose copper core power cables for fixed installation, featuring a compact solid high-purity copper conductor, cross-linked polyethylene insulation, and an extruded PVC outer sheath. Unlike armored YJV22, aluminum core YJLV, and alloy series cables, YJV cables eliminate the additional metal armor structure, achieving a compact

1. Core Product Definition and Structural Comparison Matrix VV-type cables are low-voltage power cables featuring copper conductors, PVC insulation, and PVC sheathing. Designed specifically for fixed indoor power transmission, they are suitable for applications that do not require special fire resistance, high-temperature tolerance, or resistance to prolonged outdoor exposure. Their dual-layer PVC composite structure offers balanced basic insulation and physical protection,

YJV Cable Product Overview YJV is a mainstream unarmored fixed power cable that conforms to GB/T12706 standard and IEC 60502 international specification. Its conductor is solid/compacted high-purity electrolytic copper, the insulation layer is cross-linked polyethylene (XLPE), and the outer sheath is extruded PVC. Unlike the alloy-based YJHLV series and the armored YJV22 series, YJV eliminates the additional metal armor layer, achieving a compact outer diameter, lightweight
