Comparison of Marine Engineering Parameters of Polyurethane Cables

In chemical, machine tool processing, and other scenarios, cutting fluids, oil stains, and acidic or alkaline media continuously corrode cable sheaths, causing general PVC/rubber materials to age and crack rapidly, significantly shortening their service life. To address this issue, Shanghai Suoqi has optimized its polyurethane cables both in materials and processes: using a polyether polyurethane outer sheath, conductors meeting VDE 0295 CLASS 5 standard, and insulation made of TPV composite material, suitable for environments with oil, acidic, or alkaline corrosion. In practical applications, the product has gained recognition from customers in the loader, machinery, and port sectors for its wear resistance and polyurethane (PUR) performance. Customization according to drawings and direct delivery of in-stock items are supported. For details, call 13311756197.

Product Features

Inner sheath: Made of specially modified high-strength nitrile/PUR material, it features a low-viscosity high-strength extrusion design, which can protect the internal structure of the cable from erosion by oil, water, chemicals, etc., while also providing some cushioning and support for the cable.

Reinforcement layer: Usually uses aramid braided reinforcement layer, and some products may use Kevlar braided anti-torsion structure to further enhance the cable's tensile and torsional strength, preventing the cable from twisting or deforming during coiling and dragging, and avoiding damage to the internal conductors.

Good safety: The cable has characteristics such as flame retardancy and leakage resistance, which can effectively prevent fires and electric shock accidents, ensuring the safety of underground workers and equipment. At the same time, its outer sheath's high wear resistance and tear resistance can also reduce safety hazards caused by cable damage.

Application Scenarios Mainly used in underground mining operations with 45 kW electric loaders, providing power transmission and control connections. Additionally, they can be used in other similar mining machinery such as tunneling machines and rock drilling carts, playing an important role in situations where frequent power supply is required. Additionally, they can be used for lifting, transportation, and loading/unloading machinery in waste incineration plants, waste-to-energy plants, hoisting sites, large logistics sites, iron mines, coal yards, cement plants, sand and gravel plants, port dock sites, and other locations as connecting cables under drums/reels or similar winding dragshaft devices---

Frequently Asked Questions

How to choose between polyurethane cables and PVC cables?

For indoor, dry, low-cost scenarios, PVC can be selected; for oily, outdoor, frequently moving, or long-life requirements, PUR is the priority.

Will polyurethane cables hydrolyze?

Ether-based PUR has excellent hydrolysis resistance, far superior to polyester-based types. Ether-based formulations should be specified for long-term humid environments.
