windings

Crafted from high-quality copper, ensuring excellent conductivity and reliability.

Both HV and LV windings are precision-made by coil winding machines. The carefully selected copper or aluminum strips/wires, covered with paper insulation, deliver optimal performance.

oil tank

The oil tank serves as the enclosure for the liquid dielectric power distribution transformer's iron core, windings, and transformer oil.

With a fully sealed corrugated tank design, it expands and contracts with oil volume changes, keeping the transformer oil immersed type isolated from the air to prevent oil degradation and moisture ingress. After undergoing oil removal, rust removal, and phosphating, the tank's surface is painted with weatherproof coating to resist moisture and salt spray.

Q: What is ester oil in transformers?
A: Ester oil in transformers is a biodegradable insulating and cooling fluid, offering higher fire resistance and environmental safety than traditional mineral oil.

Q: What is an oil-filled transformer?
A: An oil-filled transformer is an electrical device that uses insulating oil (like mineral or ester oil) as both a coolant and dielectric medium. The oil helps dissipate heat generated during operation and prevents electrical arcing between components, ensuring safe and efficient power transfer between voltage levels. It is widely used in power grids, industries, and commercial settings for its reliability and thermal performance.

Q: What kind of oil is used in transformers?
A: Transformer oils mainly include three types:
Mineral Oil: Derived from petroleum, it offers good insulation and heat dissipation but is flammable and non-biodegradable.
Synthetic Oil (e.g., Silicone Oil): Chemically produced, it is heat-resistant, non-flammable, and used in high-temperature or fire-sensitive environments.
Ester Oil (Natural/Synthetic): Extracted from plants or chemically synthesized, it has low flammability, biodegradability, and is eco-friendly, suitable for indoor use or ecologically sensitive areas.
