On the wiring of energy-saving distribution cabinet, if the design is reasonable, the production cost and indoor power consumption cost of energy-saving distribution cabinet can be controlled within the qualified range. Therefore, in order to master certain technologies and skills and skillfully apply wiring design, it is a necessary means in power safety measures. The load center of gravity of the energy-saving distribution cabinet shall be re divided, and the equipment shall be located close to the load center, set in the place with less dust, less corrosive medium, dry and slight vibration, and appropriate room for development shall be reserved; The layout of distribution lines shall avoid the influence of external environment: the influence of thermal effect caused by external heat source shall be avoided, and the damage caused by water intrusion or body objects during use shall be prevented.
