Non-encapsulated Dry Type Transformer

Jiangsu Yawei Transformer Co.,Ltd. is one of the leading manufacturers and suppliers of non-encapsulated dry type transformer in China. Please feel free to buy high quality non-encapsulated dry type transformer from our factory. Customized orders are welcome.

Non-encapsulated dry-type transformers are a specific type of dry-type transformer where the windings and core are not encased in an insulating material such as resin. This design relies on air for insulation and cooling, making it distinct from encapsulated types.

Cooling and Insulation:

Air serves as the primary medium for cooling and insulation.They may have ventilated enclosures to enhance air circulation.

Construction:

The windings and core are typically coated with varnish or similar protective materials but are not sealed in resin or other encapsulants.This design makes them less protected against environmental factors like moisture and dust compared to encapsulated transformers.

Maintenance:

Require regular cleaning and maintenance to prevent dust accumulation and to maintain efficiency.Easier to inspect and maintain due to the exposed components.

Safety and Fire Risk:

Generally have a higher fire risk compared to encapsulated types because the windings are more exposed.Often equipped with temperature monitoring and fire-protection systems.

Size and Weight:

Usually lighter and more compact than encapsulated transformers since they lack the additional bulk of encapsulating material.

Cost:

Typically less expensive than encapsulated transformers due to simpler manufacturing processes.

Applications

Industrial and Commercial Settings: Suitable for controlled environments where the risk of moisture and dust is minimal.Indoor Installations: Often used in indoor applications where space is a constraint and environmental conditions are controlled.Utility Substations: Commonly found in electrical substations where they can be installed in a controlled environment.
