What is the insulation tube?

by:Mings     2020-07-20

indoor high voltage vacuum circuit breaker with insulation cylinder, the top and middle equipped with wire arm respectively, through the outlet on the arm bracket with the arcing chamber static fixed connection, through to qualify under the arm bracket, soft connection and under vacuum arcing chamber conductive rod coupling dynamic end, insulation tube at the top of the internal and external to the square structure, the lower internal and external to the circular structure, insulation tube inside and outside have skirt structure, its skirt for a whole circle circle structure, the upper and lower bracket directly fixed on the insulation tube inside. Advantages: easy installation, circuit breaker and good consistency; Guide for arm and arcing chamber into a whole; Can be like a chimney convection effect; To prevent foreign body and dust, the creepage distance to satisfy requirements.

indoor high voltage vacuum circuit breaker with insulation tube, equipped with wire arm respectively on the top and middle, at the top of the line on the arm through the upper bracket with the arcing chamber static fixed link, to qualify under the arm through the lower bracket installation, central soft connected with the vacuum arcing chamber dynamic conductive rod coupling, is characterized by insulating tube for the quartet structure at the top of the inside and outside, inside and outside the lower to the circular structure, insulation tube inside and outside have skirt structure, its skirt for a whole circle circle structure, the upper and lower bracket directly within the insulation tube with screws.
