Liquid Filled Distribution Transformer

Zhejiang Jiangshan Hengli Electrical Co., Ltd. is one of the leading manufacturers and suppliers of liquid filled distribution transformer in China. If you're going to wholesale durable liquid filled distribution transformer made in China, welcome to get pricelist from our factory. All customized products are with high quality and low price.

The 800kVA Liquid Filled Distribution Transformer is engineered for high-demand electrical systems requiring reliable and efficient voltage transformation.The rated power of the transformer is 800kVA, the primary voltage and secondary voltage of this Liquid Filled Distribution Transformer are 33/0.4kV. As a leading transformer manufacturer and supplier, we provide factory-direct solutions with full customization capability, ensuring that each transformer meets specific project requirements.

Designed for stepping down medium voltage (such as 33kV) to low voltage (415V), this Liquid Filled Distribution transformer is widely used in industrial plants, infrastructure projects, and renewable energy systems. It combines advanced design, high-quality materials, and strict manufacturing standards to deliver long-lasting performance.

This 800kVA oil-filled distribution transformer is widely used in:

Core Technology

The transformer core is made from high-permeability silicon steel with multi-step lap construction. This reduces no-load losses and improves magnetic efficiency, making it suitable for continuous operation.

Winding System

The windings are designed with optimized ampere-turn balance and compact structure. High-voltage windings are placed externally with reinforced insulation, while low-voltage windings are positioned internally for better mechanical stability.

Oil & Cooling System

The insulating oil provides dual functions of electrical insulation and heat dissipation. Natural oil circulation ensures efficient cooling, while optional forced cooling systems can be added for higher performance.

Tank & Protection Design

The sealed corrugated tank prevents contamination and reduces maintenance requirements. Additional accessories such as pressure relief valves, temperature indicators, and Buchholz relay can be installed for enhanced safety.
