Description

Scope of application

　　This product is suitable for the connection of nuclear power station thermocouple, recorder, computer and data processing system.

　　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 ℃. 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 under normal operating conditions in the reactor building is 25Mrad and the cumulative dose under accident operating conditions is 60Mrad.
