FIELD: electricity.
SUBSTANCE: invention relates to electrical engineering, particularly to the method of manufacturing polar components of a switch or block of constructive elements from polymers for low-voltage distributors, distributors for medium voltage and high-voltage distributors, and also to polar components of switches of a vacuum arc-quenching chamber with an outer isolating jacket. In order to obtain simplified technology of manufacturing with a higher variability in the qualities of a material, in accordance with the invention it is suggested, that the outer insulating jacket be manufactured by the method of pouring the polymer at high pressure, and the vacuum chamber is coated by extrusion method at a pressure of P ≥ 80 bar.
EFFECT: preventing the possibility of cracking of the coating from epoxy resin after pouring or during the alternating thermal load.
