In harsh working conditions such as mining and port loading and unloading, ordinary winding cables frequently encounter issues like sheath cracking, conductor breakage, internal twisting, and bulging, leading to equipment downtime and high replacement costs. To address this pain point, Shanghai Suoqi has made targeted optimizations to its reel cables, from materials to manufacturing processes: the conductor uses multi-stranded ultra-fine oxygen-free bare copper wire (VDE 0295 CLASS 5/6 standard), the sheath is made of imported polyurethane (PUR) compound, and a double-layer sheath with a tensile braided layer strengthens the structure, preventing twisting and bulging. In practical applications, the product has been recognized by customers in wet spraying, mining, and construction fields for its wear resistance, oil resistance, and weather resistance. Insulation: Special TPV compound, insulation thickness 0.6mm - 2mm, insulation temperature range -40℃ to

Frequently Asked Questions

What is the minimum bending radius of a reel cable?

Generally, it should be no less than 6 times (6D) the outer diameter of the cable. For reel winding and unwinding conditions, it is recommended to check according to the diameter of the equipment drum to avoid long-term bending that could cause the sheath to crack.

Why is a Kevlar tensile layer used in reel cables?

During winding and unwinding, the cable is subjected to continuous axial tension. Aramid/Kevlar tensile fibers can share the tension, preventing the conductor from being elongated or deformed and ensuring stable electrical performance.
