Mining Conveyor Pullwire Cable – Custom Control Hybrid Cable Multi-Conductors 5 Cores TC/HDPE/SSB/TPU 3x1.5 + 1x2 + 1x1 Red

Mining Conveyor Pullwire Cable – Custom Control Hybrid Cable Multi Conductors 5 Cores TC/HDPE/SSB/TPU 3x1.5 + 1x2 + 1x1 Red

This custom control hybrid mining cable is specifically engineered for conveyor pullwire emergency stop systems and critical control applications requiring extreme mechanical protection with flexible, durable construction. The 5-core hybrid configuration includes three 1.5mm² cores, one 2mm² core, and one 1mm² core, providing versatile power and control circuit integration.

Conductors utilize TC tinned copper with optimized stranding: 30/0.25 for 1.5mm² cores, 28/0.30 for 2mm² core, and 32/0.20 for 1mm² core, ensuring excellent flexibility and corrosion resistance. HDPE insulation provides stable dielectric properties with color coding: red, grey, and orange for 1.5mm² cores; black for 2mm² core; yellow for 1mm² core. Non-hygroscopic filler materials maintain core geometry and prevent moisture ingress. The five cores are stranded with Mylar tape binder, followed by SSB stainless steel 316 wire braiding with 80% coverage for exceptional mechanical protection against abrasion, cutting, and impact. The outer TPU (polyether polyurethane) sheath in red delivers LSZH (low smoke zero halogen), fire retardant, UV stabilized properties with high visibility for safety system identification. Rated -25°C to +70°C with 4kV spark test verification, this cable is ideal for underground mining conveyor emergency pullwire systems, tunnel safety circuits, and heavy industrial emergency stop applications requiring flexible, mechanically robust cabling.
