Brief introduction of XLPE insulated power cable
Since the 1960s, China has replaced oil-paper insulated power cables with its excellent electrical performance, good overload, high voltage, large transmission capacity, light weight, no drop limit, and vertical laying characteristics, and has made considerable progress in XLPE cables. progress. Convenient installation, operation and maintenance, etc., XLPE cable can not only be widely used in the low- and medium-voltage range of 35 KV and below, but also can be widely used in 66, 110 and 220 KV high-voltage transmission lines. Moreover, in some developed industrial countries, 500 KV ultra-high voltage XLPE cables have been opened.

Selection of cable rated voltage:
The rated voltage of the cable should be suitable for the system voltage and use conditions of the cable used, expressed in U0 / U (Um), which are all effective values and the unit is KV.
U0-the rated voltage between the cable design conductor and the shielding layer or metal sheath.
U ---The rated industrial frequency voltage between conductors used in cable design.
Um-the maximum voltage of the equipment (the maximum voltage used or the maximum value of the equipment system).
The difference between XLPE cable and PVC cable
The main difference:
1. The maximum operating temperature of the conductor: XLPE cable has a higher rated current and longer service life than PVC cable. PVC insulated cable is 70 degrees Celsius, while XLPE is 90 degrees Celsius.
2. The highest short-circuit (duration less than 5 seconds) temperature: under short-circuit conditions, the PVC insulated cable is 160 degrees Celsius, and the cross-linked polyethylene is 250 degrees Celsius.
3. Compared with PVC, its moisture resistance is 100 times higher.
4. Service life: Generally, XLPE insulated cables are longer than PVC insulated cables.
5. Price: Generally, the price of XLPE insulated cables is higher than that of PVC insulated cables.
6. Waterproof performance in the application environment: PVC insulated cables are better than XLPE insulated cables.
7. Environmental protection: Since XLPE does not contain chlorine and will release toxic gas after burning, XLPE insulated cables are more environmentally friendly than PVC insulated cables.
The main difference between the two is that XLPE can be used for high tension and low tension applications. Its structure has good wear resistance, stress resistance and other wear resistance. PVC insulation cannot withstand that much pressure, which means it is only suitable for low-tension applications.
