Conductive 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.
- Compact and novel construction, utility model patent
- Good seal, inductive part is immune to outside environment
- Self-lubricating, maintenance-free, long-term operating
- Current conduction inside the bearing, stable and reliable
