High-voltage isolating switch GW4-126D

3-poleACdouble-column

GW4-126D double-post horizontal outdoor AC high-voltage isolating switch is suitable for power systems with AC frequency of 50Hz and rated voltage of 110kV, for high-voltage lines to be switched under no-load conditions, and for high-voltage busbars, circuit breakers and other electrical equipment under maintenance It is used for electrical isolation from live high-voltage lines to provide a visible insulation distance that meets the requirements for the equipment to be overhauled and maintenance personnel. • Adopt double-column horizontal rotating structure; • Simple structure, convenient debugging, beautiful appearance; • The isolating switch can be used in a single pole, and can also form a three-pole linkage through the interphase connecting rod; • There are two operation modes: electric and manual; • With mechanical and electrical double interlock; • The parts and components are mostly made of aluminum alloy, and adopt special anti-corrosion treatment, which has strong outdoor corrosion resistance; • The conductive contact parts are treated with silver plating, and the silver-plated surface is dip coated with antioxidant to prevent the switch from being oxidized.
