For the equipments in the mine are specially needed fire and blast protection, the rescuing communication equipments are relatively large and heavy, affecting the rescue sufficiently carried out.

And the applying of SCA in communication equipments is under researching.

The paper analyzes the function and value of design and presents some design strategies for communication equipments.

Transitional construction scheme of communication equipments in the running railway line;

The commonly used maintaining methods of communication equipment;

Development of automatic testing system on radio communication equipment;

Electromagnetic shielding technology used in telecommunication equipments arch itecture design;

The article mainly introduces the composition of telecommunication,the power source system and characteristic,expatiates mostly maintenance of storage battery and measure ways of thunder guard to telecommunication equipment,and then grounding of telecommunication power source system and telecommunication equipment,stresses importance of strengthening telecommunication power source manage.

According to the demand of telecommunication equipment EMC , the EMC design method from mechanism is put forward in detail in this paper.
