Transformer Accessories

Transformer systems require components with strong insulation performance and long service stability. We have been manufacturing power equipment parts since 2011 and have supplied transformer-related components to Sany Heavy Industry, whose electrical systems operate under continuous load conditions. This experience supports our capability in insulation-focused engineering parts.

This Transformer Accessory is used in oil-filled transformers, dry-type transformers, and box-type substations. It is designed to provide stable insulation, resist aging, and maintain safe operation under long-term electrical load.

Materials include cold-rolled steel, stainless steel, insulated bakelite, engineering plastics, and ductile iron, selected to meet structural strength and insulation requirements.

This Transformer Accessory is designed with insulation grades ranging from Class B to Class F, ensuring suitability for different temperature and electrical load environments.

The protection rating ranges from IP54 to IP65, providing reliable resistance against dust and water ingress.

Machining accuracy is controlled to IT7–IT8 grade standards for consistent assembly and sealing performance.

The operating temperature range is -40°C to 120°C, ensuring stable performance in both cold and high-temperature environments.

Surface treatments include zinc plating, electrostatic powder coating, anti-corrosion coating, and passivation to enhance durability and environmental resistance.

Sealing structures are designed to prevent leakage and maintain oil pressure stability in transformer systems.

We provide more than individual components-we deliver complete supporting solutions for transformer systems.

This Transformer Accessory is used in transformer tanks, cooling assemblies, bushing flanges, terminal blocks, and sealing covers.

It is suitable for oil-filled transformers, dry-type transformers, and substation equipment.

With over a decade of experience since 2011, we are committed to producing reliable power system components that meet strict electrical industry requirements.
