Pad-mounted Transformer

Pad-mounted transformer is a product widely used in the distribution system, and different from kiosk type transformer, it is not a simple combination of transformers and high/low-voltage switchgears, but the development of a comprehensive electrical equipment from the  transformer. It is characterized by the high side load switch and ring network and simplify the structure of the integrated transformer immersed in the same tank, thus greatly reducing the volume, cost reduced accordingly; Another feature is the use of dual fuse protection, fuse having a both current and temperature sensitive characteristic, protection sensitivity and reliability are greatly enhanced. Pad-mounted transformer's fully enclosed and insulated properties make installation quick and easy, can avoid the pain of long-term maintenance. Therefore, since the 1980s, Pad-mounted transformer is widely used in Europe and the US distribution system, particularly in the US, this pad-mounted transformer accounted for 80%-90% in distribution transformers. In the early 1990s as Cooper represented pad-mounted transformer began to be introduced to China, after years of development, there are more than tens of thousands of pad-mounted transformers serving in the domestic power distribution system, widely used in industrial parks, residential areas, commercial centers and high-rise buildings, etc.
