It is used for return circuit of class IE category K3 outside security housing of nuclear reactor in nuclear power station. 

Executive Standard 
As the enterprise's enterprise (with reference to "Design & Manufacturing Regulations on Electric Devices of Nuclear Island of RCC-E Reactor in Nuclear Power Station" of France & "Technical Specifications of 0.6/1kV Control Cable" by No. 2 Research & Design Institute of Nuclear Industry) 

Main features 
1. The cable, which is located outside security housing of nuclear reactor, keeps itself in normal operation under normal circumstance and earthquake loading. It belongs to category K3 by quality appraisal procedure. 
2. It has flame-retardant performance free from halogen with low smoke and low spreading speed, smoke density and poisonous gas emission in fire disaster, which results in low corrosion on instruments and devices. It could meet special environmental demands of nuclear power station. 
3. Cables for nuclear power station include 5 categories: 
Power cable of rated voltage 6/10kV or lower, control cable, instrument cable, compensational cable, & optic fiber cable.
