What is a spiral spring cable (spring wire)

Spiral spring cable (spring wire) is a type of equipment connection wire that works by utilizing scalability. Almost all industries may use spiral cables. Generally made of TPU material cable winding, it is mainly used for equipment with rated AC voltage below 450/750V or DC voltage below 6V-1000V, to control the electrical connection of movable equipment movement, and can quickly rebound in a short time. It is widely used in movable equipment such as telephones, computers, automobiles, trailers, soot blowers, lifting equipment, medical equipment, port machinery, instruments and meters.

Divided by direction: there are mainly left direction coil springs and right direction coil springs.

According to material, there are mainly PVC spiral spring cables (spring wires), PUR spiral spring cables (spring wires), PA spiral cables, and rubber spiral spring cables (spring wires); PUR spiral spring cable (spring wire) is becoming increasingly widely used as a material for spiral spring cable spring wire due to its flame retardancy, oil resistance, acid and alkali resistance, low temperature resistance, UV resistance, wear resistance, and hydrolysis resistance.

PVC spiral cable has a low price but poor performance, is not easy to rebound, and is inferior to other cables in terms of electrical and physical performance. It is mainly used in low-end equipment such as telephone lines.

Rubber spiral cables are priced higher than PVC spiral cables, but due to their poor elasticity and easy adhesion, they have not been widely used in China.

PA spiral cable has a high price and superior performance in all aspects, but due to its high hardness and strong resilience, it is difficult to control during use, so its application range is not wide.

PUR spiral cable, a new type of cable material made of spiral cable, has a wide range of applications and excellent performance. PUR spiral cable has many excellent chemical properties, such as oil resistance, hydrolysis resistance, weak acid and alkali resistance, anti-aging, UV protection, microbial corrosion resistance, and many excellent physical properties, such as wear resistance, tear resistance, and good elasticity. Gradually becoming the dominant type of spiral cable replacing other types of spiral cables in the market.
