Product Description

Cooling methods of single transformers:

Natural air cooling: It is the most basic cooling method. The heat generated during the operation of the transformer is naturally dissipated into the surrounding air through the tank wall, radiators and other surfaces. To increase the heat dissipation area, the transformer is usually equipped with heat dissipation tubes or fins. This cooling method has a simple structure, low cost and convenient maintenance, and is suitable for small-capacity

Oil-immersed self-cooling: In this method, the windings and core of the transformer are immersed in the transformer oil. The heat generated during the operation of the transformer is transferred to the transformer oil, causing the temperature of the oil to rise. The hot oil will naturally rise, and the heat is dissipated through the tank wall and radiators. The cooled oil will flow back to the bottom of the transformer, forming a natural circulation. The oil-immersed self-cooling method has better heat dissipation effect than natural air cooling and is suitable for medium-capacity transformers. transformers.

Specification

Unitary transformer

The single phase overhead distribution transformers are specifically designed for the decentralization distribution network of servicing residential overhead distribution loads of town and countryside. They are also suitable for light and diversified power applications. These transformers are designed for the application conditions normally encountered on electric utlity power distibution systems.

Single phase pad mounteddistribution transformers willfocus on traditional Pad mounted housingdesign, with features of smallsize, light weight,low noise level low loss high reliability, hermetically sealed. Fullyinsulated compactstructure.beautiful appearance volumeis only 1/3 ofthe box-type substation (European box typ transformer).Alldistribution rooms Can be directly placed in the indoor or outdoor It can also be placedin the streets and the area belt and reliably ensure personal safety, both supplyfacilities butalso decorate the environment.Widely used in residential areas, commercial centers, stations, airports,factories businesses hospitals, schools and other places.

Dry Transformer 

1. Coil Winding
Low-voltage coils
Typically made of copper foil or layer-wound copper wire to enhance conductivity and mechanical strength.
High-voltage coils
Mostly wound with copper wire, adopting segmented or continuous structures to ensure insulation and heat dissipation performance.
Insulation materials
Polyester films, Nomex paper, or epoxy prepreg materials are used for interlayer insulation.
