1、 Application fields of spiral cable:
It is applicable to the summary wiring of assembly circuits that move back and forth, up and down, and repeatedly. Such as computers, electronic equipment plug-ins, medical massage equipment, loading and unloading equipment, cars, trailers, spring cables, etc. As well as high-end electrical equipment with high requirements for flexibility and occasions with poor use environment!
2、 Classification of spiral cable:
Spiral cables mainly include spiral cables, power spiral cables, spiral optical cables and communication equipment spiral cables according to their applications. It is divided into pur, PVC, PA and rubber spiral cable according to sheath materials.
Pur spiral cable
1. Pur spiral cable has many excellent chemical properties such as oil resistance, hydrolysis resistance, weak acid and alkali resistance, microbial corrosion resistance, aging resistance and UV resistance.
2. Excellent physical properties such as bending resistance, wear resistance, good elasticity and tear resistance.
3. Long service life, good stability can be maintained after continuous work for multiple shifts. It is suitable for mobile occasions where the outer sheath has high mechanical stress requirements and the cable can expand and contract rapidly.
4. At present, PUR spiral cable is widely used, and the price is slightly higher.
PVC spiral cable: weak elasticity, slow rebound, high cost performance ratio, low mechanical force and chemical resistance, and inferior electrical and physical properties to other cables. It is mainly used in low-end equipment and places with low requirements for spring elasticity!
PA spiral cable: its hardness is too high, its resilience is strong, its price is high, its electrical and physical properties are superior, and its application is not extensive.
Rubber spiral cable: not widely used because of its poor elasticity and easy to stick.
3、 What are the characteristics of spiral cable?
1. Compared with the straight cable, the spiral cable has strong elasticity and fast rebound, which can restore the original state in a short time. It is easy to stretch and will not be in a mess. It has good anti signal interference and electromagnetic interference.
2. Soft conductor structure is adopted, with good flexibility, flexibility and high resilience (the elongation length can reach 3-5 times of the original spring length).
3. Long service life, up to 5 million effective cycles, no need to stop the core.
To sum up, compared with other cables, spiral cables have three advantages: wear resistance, weak acid and alkali resistance, and aging resistance.
The spiral Pu cable sheath has the characteristics of high mechanical strength, excellent wear resistance, oil resistance, excellent acid and alkali resistance, outstanding compression resistance, tear resistance, wear resistance and bending resistance, etc. high and low temperature resistance is the key to the cable performance. Therefore, in the market, TPU used for advanced cables (such as control cables and power cables) is used as a covering material for protecting complex cables. The wires made by TPU can be used under various climatic and environmental conditions, and the product performance is stable and outstanding. And its use is more and more extensive.
