(1)The highest allowed operating temperature of conductor for long-term working is 90 ° C.In short circuit (Max. Long term is no more than 5 seconds). The highest temperature for conductor is no more than 250 degrees.
(2)The environment temperature should be no lower than 0 when lay. Otherwise it should be preheated.
(3)The cable is laid without horizontal drop limit. The Min. Bending radius of three core cable should be no smaller than 12 times of cable outer diameter.
(4)Working Frequency Voltage Test:.For cable with Uo of 3.6kv~18kV: 3.5Uo/5min without puncture.
(5)Partial Discharge Test: The discharge volume should be no more than 10pC under 1.73Uo for the cable.
