Vacuum Switch Ckg3 Vacuum Contactor for Substation Station

General descriptionMV vacuum contactor has the features of energy saving, fire protection, explosion-proof, small size, long life, low maintenance cost, reliable operation and non-polluting and so on ,which is widely used in metallurgy, mining, petroleum, chemical, railway, radio, communications, industrial high-frequency heating industry, energy, transportation and other power distribution system. With the technology of breaking the current , high reliability and compact structure, the contactor can be used in particularly harsh conditions. They are suitable for the control and protection (with fuses) lines, substations and distribution stations, motors, transformers, capacitors and so on.Technical parametersModelCKG3-7.2/160CKG3-7.2/250CKG3-7.2/400CKG3-7.2/630Rated voltage(kv)7.2Rated current(A)160250400630Main circuit joint capability(A/100 times)1600250040006300On-off capability of main circuit(A/10times)1280200032005000Limit breaking capacity(A/3 times)3200400045006300Mechanical life(Ten thousand times)100Mechanical lock life(Ten thousand times)10Main circuit power frequency voltage withstand(kV)32Auxiliary circuit power frequency voltage withstand(kV)2.5Power frequency voltage withstand of control circuit(kV)2Rated operating frequency(times/h)300Frequency of mechanical lock operation(times/h)30Contact opening(mm)4±0.5Overrange(mm)1.5±0.3/* January 22, 2024 19:08:37 */!function(){function s(e,r){var a,o={};try{e&&e.split(",").forEach(function(e,t){e&&(a=e.match(/(.*?):(.*)$/))&&1
