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 cable reel cables have optimized both materials and processes: conductors use multi-strand ultra-fine oxygen-free bare copper wire strands (VDE 0295 CLASS 5/6 standard), the sheath is made of imported polyurethane PUR composite, and the double-layer sheath is reinforced with a tensile woven layer for anti-twisting and bulging protection. In practical applications, the product has been recognized by customers in wet spraying, machinery, and tunnel fields for its wear resistance, polyurethane, and PUR performance.

Product Features

Oil, acid, and alkali resistance: Can resist corrosion from hydraulic oil, diesel, acids, and alkalis. Even when used for a long time in oily environments, it is not easily damaged, ensuring the stability of the cable in complex chemical environments.

Waterproof and weather-resistant: With an IP67 protection rating, it can operate stably in extreme environments ranging from -40°C to 90°C. Whether in cold northern or hot southern regions, as well as in humid and rainy or dry, dusty conditions, it can operate normally.

Flame Retardant Safety: Complies with IEC 60332 flame retardant standards, effectively preventing the spread of fire when exposed to open flames, reducing fire risk, and improving safety at construction sites.

Cable structure: Usually uses multi-strand ultra-fine finely twisted oxygen-free copper wire, meeting VDE0295 CLASS 6 standards. Alternatively, annealed oxygen-free copper wire with a purity of up to 99.9999% is available, offering excellent conductivity and flexibility, effectively reducing energy loss, and making it less likely to break during frequent bending and dragging.

Filling layer: Filled with Kevlar tensile fiber/TPE to cushion stress, prevent core wire deformation, and ensure the stability of the cable's internal structure.

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.
