Detailed Description

500 KV XLPE Insulated Power Cable

Standard

We produced according to National Standard of GB/T 22078.2-2008 of the People’s Republic of China.

Range of application

It is suitable for single-core cable’s installation and operation under normal conditions of rated voltage 290/500 KV, but it is not suitable for cable in special use, such as submarine cable.

Characteristics of XLPE cable

Rated voltage of cable is U0=290 KV、U=500 KV、Um=550 KV.

The allowable maximum temperature of cable conductor is 90℃ when it runs in normal, and 250℃ when it short circuited (Longest time is 5 s).

The allowable minimum bending radius is 20 times of cable outside diameter when installed. After installation , the minimum bending radius is recommended for 15 times of cable outside diameter.

Service environment( Place )

Lead sheath cable, is suitable for environment with more serious corrosion but no much nitric acid, acetic acid and organic matter ( Such as mud, coal and strong alkaline corrosion matter with technical force, stress and vibration etc.)

Aluminium sheath cable, is suitable for environment with minor corrosion and required to bear a certain mechanical force ( For example, connected with transformer directly and laying at bridge opening or in shaft etc.)

Metal plastic compound sheath cable is suitable for general damp and warm place , no corrosion or light corrosion and no direct contact with water and bear not so much technical force , pulling force , stress and vibration.

PVC outer sheath cable is mainly used in cable line with general fire-proof requirement and insulation requirement for outer sheath.

PE outer sheath cable is mainly suitable for directly buried laying cable line with higher requirement on outer sheath insulation, low temperature environment under 20℃, or soaked place by chemical liquid and low toxicity requirement when cable burns, when PE outer sheath is used in tunnel or shaft , fire-control and flame-retardant measures should be adopted if necessary.

Representation method of product

For example

A. Single-core copper conductor with rated voltage of 290/500 KV, nominal sectional area of 1200 mm2, so XLPE insulated corrugated aluminium sheath PVC sheath power cable will be represented as : YJLW02-290/500 KV - 1×1200 GB/T 22078.2-2008.

B. Single-core copper conductor with rated voltage of 290/500 KV , nominal sectional area of 2500 mm2, so XLPE insulated corrugated lead sheath PVC sheath longitudinally water blocking power cable will be represented as : YJQ03-Z-290/500 KV- 1×2500 GB/T22078.2-2008.
