The main materials of spiral cables can be divided into PUR and PVC. Below is a comparison of their performance:

PUR Spiral Cable

• Advantages:

  • Strong elasticity and quick rebound.
  • Can return to its original state in a short time.
  • Spiral form is aesthetically pleasing.
  • Suitable for electrical equipment with higher requirements for elasticity and for use in harsh environments.

• Disadvantages:

  • Higher price compared to PVC cable.
  • Terminal connectors do not combine as well with PUR cables (most injection-molded parts are made of PVC material).

PVC Spiral Cable

• Advantages:

  • More cost-effective, helping to save costs to a certain extent.

• Disadvantages:

  • Weaker elasticity and slower rebound.
  • Needs some time to return to the original state after being pulled apart.
  • The longer the spiral length, the heavier the cable weight, and the longer the wait time for recovery.
  • Not recommended for high-stretching frequency due to the cable’s tendency to become difficult to close between spiral circles.
  • More suitable for indoor uses where spring elasticity requirements are not high.

Reference Standards:

• UL standards
• IEC standards
