What is a hermetically sealed distribution transformer

What is a hermetically sealed distribution transformer

The equipment adopts a sealed metal shell to completely enclose the oil tank, winding, and cooling facilities. In the structural design, new components, materials, and optimized local structures are used, significantly improving the electrical strength, mechanical strength, and heat dissipation performance of the equipment.

 

Product features:

1. Transformer oil: Adopting a corrugated oil tank with a fully sealed structure, the corrugated plate wall has two functions of heat dissipation and expansion and contraction. 

2. Safety protection: Fully sealed transformers are equipped with pressure relief valves, expanding the application range of pressure relief valves and providing effective safety protection for the product.

3. Tap changer: Adopting a new type of double sealed vertical switch, the sealing performance of the switch has been improved.

 

Benefits

Maintenance-Free:

The sealed design protects the oil from oxidation and contamination, leading to a longer lifespan and requiring less maintenance.

Compact Design:

They are often shorter than conservator-type transformers because they don't require a separate expansion tank, allowing for installation in smaller spaces.

Environmentally Friendly:

By extending the transformer's life and preventing oil degradation, this design contributes to more sustainable and eco-friendly operations.
