3. Standard Applied
GB/T 12076.2-2020 GB/T 12076.3-2020
4. Main Characteristics
The max. rated temperature of cable conductor is 90℃, and the max. temperature of cable conductor is no more than 250℃ when short circuit less than 5 seconds.
5. Installation Recommendation
1) When cable installation, the ambient temperature should not be lower than 0℃, or, to be preheated.
2) Bending radius: 20D for unarmored single-core while 15D for armored. 15D for unarmored multi-cores while 12D for armored.
6. Application
The cables are applied in transmission and distribution in high voltage power lines with rated voltage from 3 to 35kV.
