In harsh working conditions such as mining operations and port loading and unloading, ordinary winding cables frequently suffer from problems like sheath cracking, conductor breakage, and internal twisting or bulging, leading to equipment downtime and high replacement costs. Shanghai Suoqi drum cables are specifically designed for such conditions, with inner composite tensile elements of galvanized steel wire rope/Kevlar fiber and an outer sheath made of imported PUR material, which is wear-resistant, waterproof, oil-resistant, and UV-resistant, with a bending radius of ≤4 times the cable outer diameter. The cables feature wear resistance and polyurethane (PUR) characteristics, widely used in wet spraying, machinery, tunneling, and other fields. Shanghai Suoqi cables are sold directly from the source factory, customizable with multiple cores and specifications as needed, in stock for nationwide delivery. Consultation hotline: 13311756197.

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.

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.
