Application:
For power transmitting and distribution lines with A.C. rated voltage 0.6/1kV,
Using Properties
1. Rated Voltage U0/U(Um): 0.6/1(1.2)kV
2. The rated temperature of conductor
The maximum assigned temperature of the cable conductor is 90'C.
During having a short circuit, lasting less than 5 seconds, the maximum temperature of the cable conductor shall not be above 250'C.
3. Ambient temperature for laying
During the cable laying, the ambient temperature must be above 0'C,
4. The bend radius
The minimum bending diameter must be above the following standard:
Item single -core three- core
Unarmored Armored Unarmored Armored
Minimum bend radius of the cable in course of installation 20D 15D 15D 12D
The minimum bend radius of the cable close to the junction box and terminal 15D 12D 12D 10D
Note: D is outer diameter of the cable (mm)
5. Laying Method
There is no limit of head drop during the cable laying.
The cable may be laid in indoor, outdoor, air and soil. The cable may be immersed in water locally.
The cable may be laid in tunnel, pipe, trench, conduit and on cable bridge. The amoured cable can be laid underground, and the wire- amoured cable can be laid vertically.
The single core cable mustn't be laid in the magnetic metal pipes.
The environment of cable laying shall be in good heat dissipation condition.
