Grid Connection Solar Transformer

Photovoltaic transformer of 10KV or 35KV normally makes voltage rise. It is integrated with transformer, switches and high voltage fuse. The insulation liquid will be as insulation and heat dissipation medium. The housing is completely sealed and is processed by sandblasting, acid pickling, parkerising, and with primer, medium painted and finishing coat to be anti-corrosion, ultraviolet ray proof, weather resistance.
