1.Outdoor Use Class H Dry Type Step down power transformer 6.6KV 13.8KV 11KV 35KV
Our power transformers are especially suitable for installation in draw-out type or fixing type switchgears as well as for power plants, substation, self-consumption transformers, power distribution, transmitter system, earthing system, community power supply system, subway, or those places where small space, fire-control, moisture-proof, are needed. Those up to 10kV can be installed in 650 ~ 1200 mm wide switchgear, up to 20kV in a 1000mm wide switchgear and 35kV in 1400 ~ 1600 mm wide switchgear.
Our series reactors are suitable for a power system of 6~10kV.They are connected serially with high voltage parallel capacitor group to depress a wave deformation in the system.
2. Product highlight
Low loss, low noise, high operation efficiency
High ability of protection against short circuit
High mechanical strength
Pre-galvanized steel frame, flame-resistant, against corrosion
With outstanding fire-proof capability: the epoxy resin is difficult to flame and self-extinguished. So it won’t lead to the second disasters, such as an explosion.
Superior in environmental performance: the epoxy resin is very stable, moisture-proof and dust-proof. It enables dry-type power transformers to run with high reliability under abominable environment.
With small volume, light and convenient for installation and alignment.
No need of a separated room.
Insulation Material: epoxy resin
Winding Material: Aluminum wire or high quality enameled copper wire (foil winding is available for power transformer)
Core: core lamination, low loss, cold rolled grain oriented silicon steel
