Scope of application: This product is suitable for rated power-frequency voltage up to 3.6/26/35 kV - kV distribution circuit for distribution power. Using features: Low rated power-frequency voltage up to Uo/U for 3.6/6 kv - including 26/35 kv. Low cable conductors allow long the highest working temperature is 90 ℃. Low short circuit (the longest duration of no more than 5 s) cable conductor of the highest temperature does not exceed 250 ℃. Low when the ambient temperature under installation should not below 0 ℃. When the bending radius: three core cable should not less than 15 times the cable diameter;Single core cable should not less than 20 times the cable diameter. Cable of rated voltage When the rated voltage of the cable shall be suitable for the operation condition of the cable system, using Uo/U (Um) KV said.
