FIELD: electrical engineering.
SUBSTANCE: switchgear has horizontally mounted power circuit breakers accommodated in tubular cases, each case having junction flanges on ends to connect next enclosed base modules such as deflecting modules that function to deflect current leads of power circuit breaker interrupting units to branching lines. Among such enclosed base modules there may be angular branching modules with respective outdoor bushing insulators as well as disconnecting switch and ground switch modules. When use is made of deflecting modules that function to horizontally deflect current circuit by 90 deg., H-circuits may be disposed so that all modules will be arranged in horizontal plane.
EFFECT: enhanced adaptability, reduced mounting height.
