The practice of using Distribution Transformers or Service Transformers in a power distribution system has been around since the early 1880's, where the distribution of A/C power was first made possible and perfected through use of these transformers. This particular transformer provides the final voltage transformation in an electrical power distribution system, stepping down the high voltage used in the distribution lines to a lower voltage for appropriate consumer level usage.Oil-immersed distribution transformers are important equipment in the distribution network and power supply and distribution systems of industrial & mining enterprises.
1.Type:Outdoor
2.Normal Service Conditions:
3.The height above the sea level is below 1000m;
4.Ambient temperature: Highest air temperature+40 ℃, Lowest air temperature-25℃
5.Relative air humidity:≤90%(+25℃)
6.installation site: no corrosion gas, No obvious dirt
For Agricultural power distribution and lighting
A.Good heat emission, big overload capacity. Can work without wind machine for long time under 130 overload, and be full load without compulsive wind cool without capacity descending under IP45 condition.
B.Perfect safe and resistance to fire operating can be combusting for long period under 800ºC and without smoke
C.Strong resistance to thermal shock(can be full load immediately at -50ºC)
D.Complete waterproof and airproof.
E.No partial discharge
F. Good hydrophobility and good resistance to alkaline cauterization and fundal influence
G. Environmental, low noise, no deleerious gas, easy to decomposition.
