The cable sheath is the "protective coat" of the cable, which directly affects its weather resistance, aging resistance and service life. Different materials of sheaths are suitable for different environments, and selecting the right material is essential to ensure the safe and stable operation of the cable!

Common cable sheath materials and characteristics

1. PVC (polyvinyl chloride)

• featureLow cost, good flexibility, excellent acid and alkali resistance, and flame retardancy.

• Applicable scenariosIndoor wiring, household appliance cables, and other common environments.

2. PE (polyethylene)

• featureGood low temperature resistance and insulation, but poor high temperature resistance.

• Applicable scenariosCommunication cables, underground buried cables, etc.

3. XLPE (cross-linked polyethylene)

• feature: High temperature resistance (up to 90 ° C), anti-aging, high mechanical strength.

• Applicable scenariosHigh voltage power cables, outdoor long-term exposure environment.

4. TPE/TPU (thermoplastic elastomer/polyurethane)

• featureHigh elasticity, wear resistance, tear resistance, suitable for mobile cables.

• Applicable scenariosFrequent bending scenarios such as robot cables and drag chain cables.

5. Low Smoke Zero Halogen (LSZH)

• featureLow smoke and non-toxic during combustion, environmentally friendly and safe.

• Applicable scenariosPlaces with high population density such as subways, hospitals, and shopping malls.

How to choose the appropriate sheath?

• Outdoor useChoose XLPE or LSZH materials that are UV resistant.

• High temperature environmentXLPE or silicone rubber sheath is more reliable.

• High environmental requirementsChoose low smoke and halogen-free materials.
