Construction:


Using characteristic:
1. The operating temperature for cores shall not exceed 70≧ when the cable is used for long pened during installation, the ambient temperature shall not fall below 0≧ and the bending radius shall not deless than 10 times of the cable overall diameter.
2. The shieding layer shall be grounded reliabyly on both ends , otherwise the reduction factory of shielding would be reduced.
3. The reduction factor of shielding would be increased with the spare cores grouned.
4. The shielded control cable shall be laid to a right amgle with the hight voltage busbar as for as possible.

Construction:



Using characteristic:
The maximum operating temperature of cores shall not exceed 70≧ when the is used for long period. The temperatue of cores shall not exceed 160≧ at short circuit for 5 seconds. The ambient temperature should not be below 0≧ during installation. The minimum bending radius shall not be less than 10 times of the cable diameter when laying . The single cable should not be laid in magnetic ducts when it is electrified with alternating current.
