Description

Scope of application

　　This product is suitable for the rated voltage 300/500v nuclear power plant sensor and electrical cabinet measurement connection.

　　Cable conductor allows the long-term working temperature is 90 ℃, short circuit when the cable conductor does not exceed 250 ℃, the highest temperature duration of not more than 5 seconds.

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

　　Plant reactor outside ambient temperature: a 10 ℃ to 55 ℃. Within the reactor building environment temperature 0 ℃, 60 ℃.

　　Maximum relative humidity :100%, atmospheric pressure :0.086 to 0.106MPa. The cumulative dose of radiation in normal working condition in reactor buildings is 25Mrad, and the cumulative dose of irradiation in accident working condition is 60Mrad.
