KU35 is indoor switchgear of 35 kV rated voltage. The switchgear is completed with BP35 vacuum circuit breaker or SF6 circuit breakers of HD4 series (ABB) and used for construction of 35 kV switchgears of close-type transformer substations.
КU35S with SF6 gas insulation are used as a part of complete (modular) transformer substation 35/10(6) kV or 110/35/10(6) kV or as a separate switchgear of indoor installation.
Enclosed-type switchgear of 35 kV (KRPZ-35) is metal enclosure, specially designed for KU35 installation. Outdoor KRPZ-35 switchgears serve as portable “ready-to-use” units for construction of modular transformer substations of 35 kV. There are two types of units – main sections with KU35 kV installed and tambour-sections. KRPZ-35 is an optimal choice when there are no sound reasons for capital construction – in oil and gas industry, transportation, in some industrial applications.
Enclosed-type switchgear of 10 kV (KRPZ-10) consists of some separate sections. All the sections of 10 kV are easily transportable and fully equipped before transportation and mounting. The sections include KU-10C or KU10(6)S indoor switchgears.
