Transformer room set point should consider the following factors

(1) should be close to load centers, distribution shorter the distance, the smaller the power loss and voltage drop, construction costs, materials fee more provinces.
(2) a short distance supply, power supply easy. When existing buildings or the construction of buried objects cause obstacles, should be considered supply routes, the study identifies the location of the power distribution room.
(3) surrounding electric meter. Should not be set in a dusty place, hot and humid places, vibration of the machine next to salt damage around the device or is likely to suffer serious flooding and tidal areas. But when this is unavoidable, appropriate measures should be adopted. Also can not be set flammable, corrosive gases and retention areas may occur. Distribution room Electric energy meter in places like 0,1,2, or explosion-proof electrical products should be structured, or explosion-proof construction. Such local distribution room set from the ground floor to the first floor height should be in 600mm or more.
Outdoor box-type substation and power transformers should adopt the cable into the outlet. The distribution of the aid should be established production houses.
(4) Equipment and out easily. In the equipment updates, additions, repairs, vehicle shall be easily accessible.
(5) easy expansion. Taking into account the future increase in the load equipment, capabilities, installation location should be left the possibility of extension.
(6) should be avoided provided in areas of poor foundation, can not be avoided, you need to improve foundation or piling construction. In addition, the location of the power distribution room set up to deal with its neighbors had no effect, no effect on the future development.
