SEGURTO (MV) SWITCHGEAR

SEGURTO BZ48 14kV Switchgear

According to the cabinet structure, SEGURTO BZ48 14kV Switchgear can be divided into four categories: metal enclosed armored switchgear, metal enclosed interval switchgear, metal enclosed box switchgear, and open switchgear. The main components of metal enclosed armored switchgear, such as circuit breakers, transformers, busbars, etc., are respectively installed in grounded metal partitions separated by metal enclosed switchgear. Metal enclosed switchgear in that its main electrical components are also installed in separate compartments, but have one or more non-metallic partitions that meet a certain level of protection.
