The key to selecting polyurethane cables is to consider the working conditions. Shanghai Suoqi polyurethane cables use conductors made of multiple strands of finely twisted oxygen-free bare copper wire, insulation made of special elastomer materials, and an outer sheath of imported polyurethane PUR/TPU, which is oil-resistant, acid and alkali-resistant, UV-resistant, and aging-resistant. They feature core advantages such as wear resistance, tensile strength, and polyurethane properties, and can be widely applied in mining, machinery, grab, and other scenarios.

Product Features

Using specially modified PVC insulation material, it has high dielectric strength and low dielectric loss characteristics. The conductor colors follow the VDE 0293 standard, making them easy to distinguish and install for maintenance.

Tensile layer: Built-in high-strength aramid woven mesh and Kevlar tensile fibers form a robust tensile system, evenly dispersing tensile force to protect the internal structure of the cable from damage.

Frequently Asked Questions

What makes polyurethane (PUR) cables so good?

PUR jackets are wear-resistant, oil-resistant, hydrolysis-resistant, and antimicrobial, with comprehensive mechanical properties superior to PVC, making them suitable for harsh conditions such as oil, humidity, and outdoor environments.

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.
