What are the advantages of THHN wire

What is THHN wire?


THHN wire is PVC insulation coated nylon, the conductors are solid and stranded, and the working temperature is -65~+105℃.

 

What are the characteristics of THHN wire?

 

1. Excellent wear resistance. It can reduce the damage to the insulation when the wire is threaded and laid. This is very important and can effectively reduce the hidden danger of latent short-circuit accidents.

 

2. Good chemical stability. Excellent hydrocarbon resistance, that is to say, excellent oil resistance, liquefied gas and gas corrosion resistance, which effectively improves the reliability and service life of the wiring (aging performance test proves that the service life of THHN cable is at least longer than that of PVC cable. doubling is 40 years or more).

 

3. High safety performance. The test results show that the THHN wire has good thermal stability and thermal shrinkage resistance. This will help to avoid the possibility of short circuit failure due to overheating of the grounding point and shrinkage of the wire insulation to expose the copper wire.

 

4. The ability to withstand a considerable short-circuit current, the short-circuit temperature for 5 seconds is higher than that of ordinary PVC cable. Because of the nylon sheath, which has a melting point of 215°C.

 

5. It has the same flame retardant properties as PVC insulation. According to the test of related experiments, the toxicity released by THHN wire's combustion is far less than that of PE.

 

 

JZD cable manufacturer provides THHN wire with complete colors and specifications. Our THHN wire is often exported to the Philippines, the United States, and South America, and has gained a good reputation.
