Mining Cable Custom Hybrid Cable Purple 1x2x4 + 1x2x1.5 PC/PE/PVC/SCR/XLPO | D502 Chinese Manufacturer: Dingzun Cable

Mining Cable Custom Hybrid Cable Purple – 1x2x4 + 1x2x1.5 PC/PE/PVC/SCR/XLPO, Chinese Manufacturer: Dingzun Cable

This custom hybrid mining cable features two shielded twisted pairs in a single assembly, engineered for reliable signal and power transmission in demanding underground and surface mining environments. The 4mm² pair consists of one twisted pair with PC plain annealed copper Class 2 conductors, HDPE polyethylene insulation in red and black, designed for power or high-current control applications. The 1.5mm² pair features PC plain annealed copper Class 2 conductors with Cellular PE polyethylene insulation in green and white, optimized for signal transmission with enhanced dielectric properties. Each pair incorporates individual Mylar tape binder, an aluminium foil screen with 30% overlap for EMI protection, and a tinned copper drain wire ensuring continuous shielding effectiveness. The 1.5mm² pair includes an additional PVC V90-HT grey bedding layer for mechanical protection. An overall Mylar tape binder secures the assembly, while the purple XLPO cross-linked polyolefin sheath provides LSZH (low smoke zero halogen), flame retardant, and UV stabilized properties essential for mining safety compliance. With temperature range -25°C to +70°C, 6kV spark test verification, and minimum bending radius of 8D, this Dingzun Cable hybrid design is ideal for mining equipment, tunneling machines, and underground communication systems requiring robust, flame-retardant cabling.
