Conductive Bearing Model 627176
Inductive bearing is an important part of HV
disconnector, which may be applied in HV electrical equipments of eletric power
transmission and converting system, to ensure reliable on-off actions of
disconnector. Also it can effectively carry heavy current and block low current
and shunt current (loop current), thus it is easy to operate the disconnectors.
High- voltage disconnector is used in the high-voltage
distribution system to isolate the parts which need to be power off from the
live parts to ensure the safety of maintenance personnel. The country requires
mandatorily that the disconnetor must be mounted in the HV electrical equipment
to guarantee the safety of operators and equipments.
In a word, conductive bearing is the most reliable
and secure choice, and the product has passed the type test from China Electric
Power Research Institute.
