Range of application
This kind of products are applied in transmission and distribution in medium voltage power lines with rated voltage 3-35KV.
Max. rated temperature of cable conductor is 90℃ in short-circuit (Max. duration less than 5s), and can’t exceed 250℃. Ambient temperature in cable laying can’t be minus, and cables need pre-heating if temperature is below 0℃. Allowable bending radius in cable laying: single core cable no less than 20 times of outer diameter while multi-core cables no less than 15 times of outer diameter.
