In harsh working conditions such as mining operations and port loading and unloading, ordinary winding cables frequently experience problems such as sheath cracking, conductor breakage, and internal twisting and bulging, resulting in equipment downtime and high replacement costs. To address this pain point, Shanghai Suoqi Reel Cables has made targeted optimizations from materials to processes: the inner layer is a composite of galvanized steel wire rope/Kevlar fiber tensile elements, and the outer sheath is made of imported PUR material, which is wear-resistant, waterproof, oil-resistant, and UV-resistant, with a bending radius ≤4 times the cable outer diameter. 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: specially formulated TPV composite material, insulation thickness 0.6mm - 2mm, insulation temperature range -40℃ to 120℃, Sheath: imported polyurethane (PUR) composite.

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.
