Cable Popular Science Series--What's the different between XLPE cable and PVC cable?

XLPE is a new insulation material. He had PE got by crosslinking. 

So theoretically, his performance is better than the PE. 

XLPE has been used in the cable industry since it was invented in the 1960 s and 1970 s.

 Until now, XLPE has become head insulation in the cable industry.

Here about the advantages and uses of XLPE Advantages of XLPE cable

XLPE 

The advantages are as follows: 

😊It can work at 90℃ high temperature for a long time.

And it has excellent heat resistance. It also means it can withstand higher current ratings.

😊Insulation enhancement and the effect of temperature on the material is reduced.

😊 All-round improvement of mechanical characteristics, no longer easy to crack due to

environmental factors. Improve heat aging performance. 

😊Reduce the harm to the environment, in line with modern environmental protection

requirements. Easy operation and maintenance

😊Low dielectric loss, cost saving.

In addition, the service life of the cable has also become longer.

Use of XLPE cable

XLPE cable has the advantages of easy laying, simple operation and maintenance, and long service life. 

Therefore, distribution network, industrial equipment and large capacity power field are very like to use it. 

In addition, the excellent performance of XLPE cable makes it suitable for any difficult terrain installation.

PVC

Let's talk about PVC, PVC appears with XLPE earlier.

The most common insulation used before the XLPE was PVC (and certainly now). It is a polymer material and is widely used.

Let me describe its advantages and uses below.

The Advantages of the PVC

😊It can be recycled

😊Physical and chemical stability

😊Very wide use

😊Cheap

Use of the PVC

It works too versatile. The artificial leather interior, floor, table cloth, gloves, cable insulation will be used in PVC.

So what is the difference between PVC and XLPE?

For convenience, I made a excel for everyone to express it.

Project name	PVC	XLPE
Max. conductor operating temperature	70℃	90℃
Maximum short circuit temperature (duration less than 5s)	160℃	250℃
Waterproof performance in application environment	Good	Very good
Thermal life	20years	40years
Environmental protection	releases toxic gases	No toxic gas is released
Price	Low	A little bit higher

If you look at the excel carefully, you will find that PVC cable only has the advantage in price, but the service life and cable performance are not as good as XLPE cable. 

Especially in environmental protection, the advantages of XLPE cable are very obvious. 

Conclusion

In the long run, I think XLPE cable is better. 

Nowadays, the world is paying more and more attention to environmental protection and product quality. 

I believe that in the near future, XLPE cable will replace PVC cable.
