ProductUsage：

This product is suitable for cross-interconnection of 110KV and abovehigh-voltage power transmission lines to enhance the safety of power gridoperation.

Usefeatures：

Coaxial cable structure, cross-connect no sense voltage.

1、Maximum rated temperature

Long-termmaximum allowable operating conductor temperature: 90 °C,Maximum operatingtemperature under short-time overload: 130°C,Maximum operating temperatureunder short circuit (short circuit duration 5 s): 250 °C

2、required

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.

2.1 Minimum bending radius of cable

During cable laying : 20D0; and Permanent installation :15D0.

Note: D₀ is measured outer diameter ofcable

2.2 Maximum 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.

2.3 Maximum allowable side pressure when cable is bent, P

P=T/R≤500(kg/m), where T is axial traction, and R isbending radius.
