ZKJ-350/3.3 MINING AC H.V. VACUUM CONTACTOR CKJ-200/3 TYOE AC H.V. VACUUM CONTACTOR 9. CKG3-7.2/160, 250, 400, 630 TYPE AC H.V. VACUUM CONTACTOR 10. CKG, KJ3-12/160, 250,400, 630 TYPE AC H.V. VACUUM CONTACTOR 11. CKG3-12 SERIES SINGLE-POLE PERMANENT-MAGNET WACUUM CONTACTOR 12. CKG3-12KV-Y SERIES PERMANCENT-MAGNET H.V. VACUUM CONTACTOR General description This series contactors are composed of insulation frame, metal base, transmission shaft and crutch, electromagnetic system, permanent-magnet, power module, auxiliary switch and vacuum interrupter and so on components. While electromagnetic coil across the control voltage, armature drives the crutch rotation to open the main contact in the vacuum interrupter. Meanwhile, auxiliary switch breaks power of electromagnetic coil, turns to be permanent-magnet maintenance. After power broke by control loop, energy storage power of power module discharges to electromagnetic coil for degaussing, and the main contact broke under the function of opening spring. 13. JCZ5-12/250, 400, 630 TYPE AC H.V. VACUUM CONTACTOR 1. ZW32-12 SERIES OUTDOOR VACUUM CIRCUIT BREAKER General description ZW32-12 series column type outdoor H.V. vacuum circuit breaker is outdoor H.V. switch equipment with tri-phase AC 50Hz, rated voltage 12KV. It is suitable for dropout, closing load current, overload current and short-circuit current of the city or the rural electrical power distribution system. Circuit breaker is brand-new miniaturized design, entire seal structure, unique explosion chamber seal technology, good sealing property, moisture-proof, guards against congeals dew, which is suitable for the high temperature and moist area. 2. ZW8-12, ZW8-12G SERIES OUTDOOR VACUUM CIRCUIT BREAKER General description ZW8-12 series vacuum circuit breaker is a H.V. outdoor switch-gear with rated voltage 12KV, tri-phase AC 50Hz, which is mainly used for making and breaking load current, over-current, short-circuit current of rural network, city network and miniature power system. The overall structure of this product is tri-phase co-box type, tri-phase vacuum explosion chamber in the metal box, the performance is reliable, and the insulation level is strong by making use of SMC insulation material phase to phase insulation and to earthing. ZW8-12G is formed with ZW8-12 circuit breaker and isolation knife, called combined circuit breaker, may use for breaking switch. The operating device of this series product is CT23 spring loaded operation mechanism, divided into two kinds of motor operation and manual operation. This breaker matches with electronic control unit to realize four remote monitor 3. ZW-12 ELECTRONIC PT TYPE OUTDOOR H.V.
