Through the high free lifting spiral cable in the sheath material, it can be classified into: PVC spiral cable, spiral cable pur, PA spiral cable, and four kinds of rubber spiral cables.
PVC spiral cable has low price but poor performance and is not easy to rebound. We do not need other cables in terms of electrical system performance and physical performance research. It can be mainly used in low-end technical equipment, such as telephone lines.
The price of rubber spiral cable is higher than that of PVC spiral cable, but it is not widely used in China because of its poor elasticity and easy adhesion.
PA spiral cable has higher price and superior performance, but due to its high hardness and strong elasticity, it is difficult to control in the process of use, which is not a wide application.
Pur spiral cable is a kind of spiral cable that can be made by developing new cable materials. It is applicable to a wide range of research and has excellent performance. Pur spiral oil hydrolysis, resistance to weak acid and alkali, anti-aging, UV, microbial corrosion and other excellent properties of chemistry, as well as abrasion resistance, tear resistance, good flexibility and other excellent physical properties, has gradually developed into an enterprise led spiral cable.
