antibiosis XLPE cables
Usefeatures:
1、Maximum rated temperature
Long-term maximum allowable operatingconductor temperature: 90 °C,Maximum operating temperature under short-timeoverload: 105 °C,Maximum operating temperature under short circuit (shortcircuit duration 5 s): 250 °C
2、Installation requirements
Cable laying shall not be restrictedby drop height; the ambient temperature for laying shall not be lower than 0 °C,and if the ambient temperature is lower than 0 °C, the cable shall bepre-heated.
2.1Minimum bending radius of cable
During cablelaying: 20D0; and Permanentinstallation: 15D0.
Note: D0 is measured outerdiameter of cable.
2.2Maximum allowable axial traction for cable installation, T (radial sidepressure at bend not being considered)
Conductor: T=K×Conductor section (kg)
Aluminum sheath:T=K×Aluminum sheath section(kg)
Where, the coefficient K=7kg/mm2for copper conductor and 4kg/mm2 for aluminum conductor and 2kg/mm2 for aluminum sheath.
2.3Maximumallowable side pressure when cable is bent, P
P=T/R≤500(kg/m), where T is axialtraction, and R is bending radius.
