ProductUsage:

This productis suitable for 110-220kV power transmission and distribution system for thetransmission of electrical energy, low smoke no accounting for the flameretardant performance higher than the national standard, widely used inairports, nuclear power plants, key water control projects, high-risebuildings, Chemical, metallurgy, petroleum, traffic and other flame-retardantproperties demanding places.

Implementationstandards:

110kV product implementationstandards: GB / T 11017 and GB / T 19666, the flame retardant properties inline with GB / T 18380 requirements;

220kV product implementationstandards: GB / T 18890 and GB / T 19666, the flame retardant properties inline with GB / T 18380 requirements.

Specifications and Name:

 110kVenvironmental-friendlyantibiosis XLPE cables

220kVenvironmental-friendly 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.
