Three Phase Oil Immersed Distribution Transformer

Name: Three Phase Oil Immersed Distribution Transformer
Brand: Zhejiang Tenrony Electricity Co., Ltd.
Availability: InStock

The 3 phase distribution transformer was developed by Tenrony based on the original distribution transformer. Through the research and application of new materials and new processes, as well as the combination of independent innovation and technology introduction, and through the optimized and innovative design of the core and coil structure, oil immersed distribution transformer aims to reduce no-load losses and noise.

As a self-developed power distribution equipment, the average no-load loss has decreased by 37%. The noise level has decreased by an average of 20%compared with the current national standard JB/T10088-2004, and the three phase distribution transformer performance level has reached the advanced domestic level.

Features

Three phase distribution transformer bases on traditional structure and mature technology. This power distribution equipment 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.

3 phase distribution transformer 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.
