2. Installation requirement
The installation of cables is not limited by the difference of level along the route. The ambient temperature should not be below 0℃ during installation. The permissible bending radius for cable shall not be less than 10 times of the cable diameter. The single cable shall be without amour or with steel wire amour when it is electrified with alternating current and shall not be laid in magnetic ducts.
