3 phase step up transformer
china electrical transformer basically follows the conventional pole transformer and distribution technology, along with the deepening of reform of power industry, especially in the study of the power grid to reduce line losses, improve enterprise efficiency process found that there are many shortcomings of a single low-voltage distribution way, line losses Great, while developed countries attach great importance to optimize the distribution voltage, residential, small commercial area hanging rods commonly used single-phase or 3 phase step up transformer transformer power supply from single-phase transformer consisting of 6kV or 10kV high voltage directly to the user; universal the use of small-capacity, dense point manner, thereby minimizing voltage lines, reducing line losses.

50 kva pole mount transformer
1, Distribution Transformer position should be set at or near the load center for easy replacement and maintenance of equipment location.
2, the poles should be installed below the transformer:
2.1, corner, pole branch office.
2.2, has received the head of the family line or cable poles.
2.3, equipped with a branch line shunt switch device poles.
2.4, the intersection of the poles.
2.5, low-voltage line connected households more poles.
2.6, easily accessible personnel or personnel-intensive area of the pole.
2.7, there are lots of serious foul pole.
3, the bottom of the pole-mounted transformer height from the ground, not less than 2.5 meters. Its live parts, should be considered the ambient conditions.
4, deflectors transformers,three phase pad mounted transformer lead on the line and bus should adopt multi-strand insulated copper wire, cross-section shall be transformer rated current selection, and not less than 16 mm2. A transformer secondary side should be installed to adapt the electrical equipment. One side of the fuse installed perpendicular distance of not less than 4.5 meters.Farady conventional pole transformer Secondary fuse or circuit breaker installed perpendicular distance of not less than 3.5 meters. Each phase fuse horizontal distance: One side should not be less than 0.5 m, the secondary side of not less than 0.3 meters.
