In harsh conditions such as mining and port loading and unloading, ordinary winding cables frequently suffer from sheath cracking, conductor core breakage, and internal twisting and bulging, leading to equipment downtime and high replacement costs. To address this pain point, Shanghai Suo Qi's reel cable has optimized both materials and processes: the inner layer of composite galvanized steel wire rope/Kevlar fiber tensile components, with an outer sheath made of imported PUR material, wear-resistant, waterproof, oil-stain-resistant, UV-resistant, and a bending radius ≤ four times the cable's outer diameter. In practical applications, the product has been recognized by customers in chemical, factory, and machinery fields for its tensile, oil-resistant, and waterproof performance. Insulation: Made with mixed elastomer nitrile / automotive material / TPE, insulation thickness 0.4mm - 1.8mm, insulation temperature resistance rating up to 105°C, sheath: imported

Product Features

Specifications Conductor: Multi-strand oxygen-free bare copper wire, compliant with VDE0295 CLASS 5 or 6 standards, single wire diameter 0.12mm - 0.2mm, conductor cross-sectional size ranging from 0.5mm² to 25mm², selectable according to equipment power requirements.

Insulation: Made of hybrid elastomer materials such as nitrile rubber / automotive grade materials / TPE, insulation thickness 0.4mm - 1.8mm, insulation temperature rating up to 105°C, insulation breakdown voltage ≥20kV/mm.

Strength Members: Includes jute filler, galvanized steel wire ropes with diameters of 1mm - 3mm, Kevlar tensile fibers, and halyard ropes; the total cross-sectional area of the strength members accounts for 10% - 15% of the cable cross-section.

Inner Sheath: Made of flexible non-woven fabric, thickness 0.2mm - 0.5mm, tightly wraps the conductor, providing good cushioning and protection.

Outer Sheath: Imported polyurethane (PUR) material, sheath thickness 1.2mm - 3.5mm, Shore hardness 85A - 95A, with excellent wear resistance and tear resistance.

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.

How to choose the type of port reel cable?

It is necessary to specify the reel diameter, winding and unwinding speed, whether it will be exposed to water, and the temperature range. Preferably choose a PUR sheath with enhanced tensile strength, and verify the longitudinal waterproofing and salt spray resistance specifications.
