POLYMER INSULATED MULTI SWITCH FOR UNDERGROUND POWER LINE

摘要

A polymer-insulated multi switch for an underground power line is provided to improve durability and insulation property, to prevent moisture generation according to improvement of sealing property, and maximize economical property and user reliability by comprising a plurality of insulating parts. A polymer-insulated multi switch for an underground power line comprises an insulating housing(1), a connector(20), a main circuit connector(25), a power line connector, and a bushing(30). The insulating housing is built in so that a plurality of the upper and lower insulating parts(10)(10') are insulated and separated. An earthed circuit connector, a main circuit connector and a power line connector are connected to one side of the upper and lower insulating parts of the insulating housing. The busing is formed in a body in order to insert and fix the earthed circuit connector, the main circuit connector and the power line connector.
