11(20)kV Hermetically Sealed Oil Immersed Distribution Transformer
Brief Description
The oil immersed distribution transformer is completely sealed against outside air and moisture to keep transformer oil clean and free from contamination. Flexible corrugated oil tank design (for cooling and heat dissipation) accommodates the change of transformer volume. Insulation material such as high-voltage bushings offers a long service life. There is no need to check up the core yoke before getting the transformer started. No maintenance or repair is required as the distribution transformer will last for years to come. Our transformer products are designed with PC CAD, built to IEC60076 and GB1094 standards.
With a no-load loss 30% less than one often seen on the market, Haolai 11(20)kV hermetically sealed oil immersed distribution transformer is durable, rigid and not easily shorted.
- Corrugated structure features fins that aid in heat dissipation.
- High voltage bushings A, B, C
- Oil level gauge displays oil level in the transformer.
Applications
Commonly placed at any power distribution sites as well as in compact substations (prefabricated substations) and mobile substations. This two-winding transformer provides two voltages on the primary side.
