Product Info 
1.Usage 
It is far better than all property targets of PVC insulated power cable and has overcome the short comings of physical and chemical crosslinkage ,and completely reaches of surpasses GBand IEC technical property value
2.Range of application
It is suitable for single-core cable's installation and operation under normal conditions of rated voltage 127/220KV, but it is not suitable for cable in special use, such as submarine cable.
3.Characteristics of cable
Rated voltage of cable is U0=127KV,U=220KV,Um=252KV. The allowable maximum temperature of cable conductor is 90ºC when it runs in normal , and 250ºC when it short circuited (Longest time is 5s). The minimum bending radius of cable installation is recommended to 20 times of outer diameter of cable.
4.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, pulling 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 fore , 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 20ºC, 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 flame0retardant measures should be adopted if necessary .
