Product Description

1. Product Introduction

Special rubber sheathed flat Cable is a highly flexible, heavy-duty flat cable designed for mobile and harsh working environments. It mainly consists of flexible stranded copper conductors, rubber insulation, load-bearing steel wire reinforcement, and a thick rubber sheath. This cable features excellent bending resistance, high tensile strength, oil resistance, abrasion resistance, and aging resistance. The flat structure effectively prevents twisting and winding during frequent movement, widely used in port machinery, gantry cranes, overhead traveling cranes, elevators, and other special equipment. It supports stable power and signal transmission under long-term reciprocating operation. With reliable performance and strong adaptability, it is ideal for various mobile power transmission applications indoors and outdoors.

2. Product Models and Specifications

2.1 Product Types of special rubber sheathed flat cable

1. Flat flexible rubber-sheathed cable
2. PVC-insulated, NBR - sheathed flat cable
3. Flat rubber cable with copper braid shielding
4. High-performance flat cable with polyurethane outer sheath

2.2 Structure of special rubber sheathed flat cable

Conductor: Multi-strand fine annealed copper, compliant with IEC 60228 Class 5/6 or VDE 0295 Class 5; extra-fine stranding for high flexibility.
Insulation: EPR (ethylene propylene rubber) or special PVC compound; color-coded or numbered for identification; green-yellow for grounding core.
Core Arrangement: Parallel flat (linear) or quincuncial core layout for compactness and anti-twisting.
Reinforcement: Two galvanized steel wires embedded on both sides for tensile strength, critical for long-span crane travel.
Shielding: High-density tinned copper braid (shielding density >80%) to resist electromagnetic interference.
Outer Sheath: Heavy-duty NBR (nitrile rubber), CSM (chlorosulfonated polyethylene), or PUR (polyurethane); oil-resistant, abrasion-resistant, UV-resistant, and salt-spray resistant.
