Long distance overhead power distribution grid and spiders

With the expansion of urban construction and economic development of modern environmental considerations, in the past that focus on blood pressure, long distance and cobweb-style overhead power distribution grid has become increasingly lagging behind the development of modern urban power supply. Now urban network  electric transformer  and transformation requires high pressure directly into the city, load center substation equipment, power transmission through underground cables,  Voltage stabilizer  equipment coordinated with the surrounding environment. Also requires safe and reliable power distribution equipment, high-performance (ie, low loss, low noise, high short-circuit strength), size is becoming smaller, easy installation, maintenance or less to maintain. Combined Transformer is such a new distribution equipment. Combined Transformer is the body of the transformer, switchgear, fuses, tap combination and the corresponding auxiliary equipment transformers.
