Medium Voltage High Voltage Power Distribution Transformer

Name: Medium Voltage High Voltage Power Distribution Transformer
Brand: Zhejiang Tenrony Electricity Co., Ltd.
Availability: InStock

The S11 high voltage electricity transmission series of fully sealed oil-immersed power transformers developed and produced by high voltage electricity transmission company has the advantages of low loss, low noise, and high efficiency, which can achieve good energy-saving effects and reduce pollution. Compared with ordinary oil-immersed transformers, fully sealed transformers eliminate the oil storage tank. The change in oil volume is automatically regulated and compensated by the elasticity of the corrugated plates in the corrugated oil tank. The oil immersed power transformer is isolated from the air, preventing and slowing down the deterioration of oil and insulation aging, enhancing operational reliability, and requiring no maintenance during normal operation.

Features

High voltage electricity transmission bases on traditional structure and mature technology, our company has made many improvements, including.

Adopting a spiral coil with longitudinal oil passages for better internal heat dissipation.

Improving the effective support of the coil end face for stronger short-circuit current resistance.

High voltage electricity transmission uses a new lifting structure and body positioning structure to ensure greater reliability during long-distance transportation and operation.

The oil tank adopts a fully sealed structure, isolating the transformer from the atmosphere, preventing and slowing down oil degradation and insulation moisture, enhancing operational reliability, and requiring no maintenance during normal operation.
