HWGボックス型開閉ステーション
HWG-12/24 series box-type switch station, also known as switch station. It is a distribution site that plays a switching role and is used to distribute electric energy; it is the link between the distribution power supply (110kV or 35kV substation) and the distribution network. It is an extension of the 10kV busbar of the distribution power supply, increasing the number of distribution power supplies. .
