Bending life of polyurethane cable for power maintenance

Key Technical Data

40℃
90℃
500MΩ
300/500V

In scenarios such as chemical industry and machine tool processing, cutting fluids, oil stains, and acidic or alkaline mediums continuously erode cable sheaths, causing general PVC/rubber materials to age and crack quickly, greatly reducing service life. Shanghai Suoqi polyurethane cables are specifically designed for such working conditions, using a polyether polyurethane outer sheath, conductor meeting VDE 0295 CLASS 5 standards, and insulation made of TPV composite material, suitable for environments with oil stains and acid-alkali corrosion. The cables feature polyurethane, PUR, and wear-resistant properties, and are widely used in marine, underwater, and port areas. Shanghai Suoqi Cable offers direct sales from the source factory, customized multi-core and multiple specifications as needed, with sufficient stock for nationwide delivery.

Frequently Asked Questions

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.

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.
