The transformer rely on air convection for cooling. With the increasing of urban power load, the crowded residentialand high-rise buildings, underground structures, there is an urgent need in transformer with these advantages: furtherload center, preventing fire or explosion and superior environmental performance,and dry-type transformer meet theserequirements.
The transformer is of high mechanical strength, ant-short circuit ability ,better moisture resistance and can be run at100% humidity without preheating treatment before operation, intermitent operation without moisture protection. Thereare advantages :small size, light weight, no cracking, no moire surface, partial discharge low,high insulation level, gooolightning shock resistant performance,free maintenance, strong heat dissipation capabilty, running 150% rated load inthe forced air cooling conditions , flame retardant, explosion-proof, no polution, and directly installed in the load center.| Rated capacity(KVA) | Voltage Combination and tap range | connection of transformer winding | No-load loss (w) |
