Usefeatures

1、Maximum rated temperature

Long-term maximum allowable operatingconductor temperature: 90 ℃,Maximum operating temperature under short-timeoverload: 105 90 ℃,Maximum operating temperature under short circuit (shortcircuit duration 5 s): 250 ℃

2、Installation requirements

Cable laying shall not be restrictedby drop height; the ambient temperature for laying shall not be lower than 0 90 ℃;C,and if the ambient temperature is lower than 0 90 ℃, 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 x Conductor section (kg)

Aluminum sheath:T x 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.
