FLEXIBLE SWITCHGEAR BUSBAR Russian patent published in 1998 - IPC

FIELD: electrical engineering. SUBSTANCE: flexible cable duct includes flexible plastic insulating casing of permanent sectional area. Casing is primarily rectangular in shape and has three depressions facing the same side of casing. Copper conductor is placed in each depression bottom and blade-type contact is connected to each conductor over its entire length so that it is electrically connected to conductor and forms double-way spring contact. Depression is also provided on opposite side of casing. Sideways bending of cable duct compresses depressions thus improving its flexibility. EFFECT: improved design. 13 cl, 19 dwg
