Zhejiang Jiangshan Hengli Electrical Co., Ltd. is one of the leading manufacturers and suppliers of output distribution transformer in China. If you're going to wholesale durable output distribution transformer made in China, welcome to get pricelist from our factory. All customized products are with high quality and low price.
This is an output distribution transformer. It is a 3-Phase Oil-Immersed step down distribution transformer designed to efficiently meet the growing energy demands of urban public utilities, featuring a rated capacity of 250kVA. The transformer is engineered for reliable performance with a primary voltage of 11kV and a secondary voltage of 0.4kV.
An output distribution transformer (often simply distribution transformer) is the final voltage transformation unit within power grid networks. It takes medium voltage electricity from secondary substations and steps it down to low voltage for commercial, industrial and residential end consumers. It receives medium-voltage power (such as 11kV, 20kV, 33kV) and converts it to low-voltage output (400V three-phase / 230V single phase), which is directly usable for end-user loads. The term "Output" highlights this transformer delivers the usable final voltage to the distribution network.

Key Features
Our 250kVA three-phase output distribution transformers are engineered to resist harsh environments and maintain stable long-term operation. All units hold CE and ISO certifications to meet international safety and quality standards. Widely applicable to urban infrastructure, commercial buildings and industrial facilities, Hengli Electrical offers custom step-up and step-down models tailored to unique power demands, delivering high efficiency for urban construction and infrastructure upgrades.
The oil-immersed transformer adopts a precision-designed internal structure. Its core is constructed from premium silicon steel to cut core losses. Primary and secondary windings use high-conductivity copper or aluminium with robust insulation to endure high voltage. Immersed in high-grade mineral oil, the unit achieves efficient cooling and insulation. Key components cover the silicon steel core, insulated windings, insulation system, oil cooling system and tap changer for flexible voltage adjustment.
