Three Phases Power Distribution 500KVA Transformer Resin 33kV

 Power Distribution Transformer Application

1). 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.

2).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.

Main Features of Power Distribution Transformer

1).Low loss, low noise, high operation efficiency
2).High ability of protection against short circuit

3).High mechanical strength  
4).Pre-galvanized steel frame, flame-resistant, against corrosion

5).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.

6).Cast epoxy resin with high dielectric strength 18~22kV/mm in vacuum process

7).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.

8) With theimpeccable temperature control and indicating system, dry-type power transformers can be maintenance free. And this offers a great reduction of operation cost.

9).With small volume, light and convenient for installation and alignment

10).No need of a separated room

1 The  power distribution transformers are packed with wooden packages, and must always stand up according to the direction mark of the packages (except for the 220kV current transformers, they are always packing and transport by lying down).

2 You must remove the wood plates of the top and obverse when you open the package, and then dismantle the 4 pcs M16 bolts which fix in the frame of the package, lift up the voltage transformer vertically and slowly from the package.

3 The clients must check the packages when they receive the voltage transformers, if a package has been broken, they must open the package to check the product together with the forwarder, note down the process and send to the manufacturer.
