Description

Scope of application

　　This product is suitable for power plant rated voltage 6/10kv transmission and distribution system.

　　Cable conductor allows the long-term working temperature is 90 ℃; Short circuit when the cable conductor does not exceed the highest temperature of 250 ℃; Duration not exceeding 5 seconds.

　　When environment temperature is lower than 0 ℃ when cable laying should be preheated.

　　Plant reactor outside ambient temperature: a 10 ℃ to 55 ℃. Reactor in ambient temperature of the plant: 0 ℃, 60 ℃.

　　Maximum relative humidity :100%; Atmospheric pressure :0.086 to 0.106MPa,

　　The cumulative dose of radiation at normal working conditions in the reactor building is 25Mrad; Cumulative irradiation dose under accident condition 60Mrad.
