0.4-72.5kV Sammelschiene

Insulation busbar features: 1.Conductor is tube type , lower skin effect ,larger ampacity of unit cross-sectional area. 2.Using capacitance voltage-sharing insulation, equally distributed electric field and better electric insulation performance . 3.Each phase insulation is sealed separately, avoiding invation of water, humidity and dust . 4.The insulation busbar is stronger than the rectangle busbars in mechanical strength, bearing larger short circuit current, installing larger span. 5.The busbar can be fixed directly on the support, cancelling wall bushing and ,having stronger ability of resisting earthquake. 6. Convenient installation,maintenance-free. 7. Have excellent seismic performance
