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. KU35 is used both as a part of complete (modular) transformer substation 35/10(6) kV or 110/35/10(6) kV or as a separate swithchgear of indoor installation (say, in factory shops, foundries, etc). The cabinet of KU35 complete switchgear is separated to compartements: for busbars, for withdrawable element wit vacuum circuit breaker, one or two compartments for relay protection systems. It is possible to provide leads-in from the top or/and from the bottom, to choose any direction of  leading-out busbars. KU35 complete switchgears for a long time has been a unique developments for CIS and Eastern Europe. 

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.
