Tunnel Engineering Maintenance of Polyurethane Cables

Key Technical Data

In scenarios such as chemical engineering and machine tool processing, cutting fluids, oil stains, and acidic or alkaline mediums continuously corrode cable sheaths, causing common PVC/rubber materials to age and crack rapidly, significantly reducing service life. Addressing this issue, Shanghai Suoqi's polyurethane cables have been specifically optimized in both materials and processes: the conductors use multi-stranded, finely twisted oxygen-free bare copper wire; the insulation is made of special elastomer materials; the outer sheath is imported polyurethane PUR/TPU, which is oil-resistant, acid and alkali-resistant, UV-resistant, and aging-resistant. In actual applications, the product has been recognized by customers in marine, underwater, and mechanical fields for its wear resistance, tensile strength, and corrosion resistance. Customization according to drawings and direct shipment from stock are supported. For details, please call 13311756197.

Product Features

Marine-grade cables are specially designed and tested to withstand extremely high water pressure, ensuring reliable transmission in deep-sea environments.

3. Resistance to biological corrosion: Marine environments often contain large amounts of marine organisms, which may cause damage to cables.

Our seawater-resistant cables use special jacket materials and structural designs, which can effectively resist corrosion from marine organisms and protect the stability and reliability of the cables.

4. Strength and flexibility: Seawater protection cables possess excellent mechanical strength and flexibility, capable of withstanding intense movement, tension, and twisting in marine environments.

They are suitable for marine applications that require frequent wiring and bending.

Application scenarios

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.

What is the temperature resistance of polyurethane cables?

Conventional polyether PUR is suitable for temperatures from -40°C to 90°C, and can be higher in the short term. When selecting, consider ambient temperature and mobile status for confirmation.
