KCC6C-7.2kV
series AC vacuum contactor is the next-generation product developed by the company in response to the market needs, it can completely meet the latest requirements of 6kV networkThe. company has summarized users' experience through many years and redesigned the original product, therefore, we have remarkably improved the product both in performance indexes, reliability and easy maintenance，they can be reliably used in capacitive load switching (make-and-break of transformer bank(AC-6a) and the make-and-break of capacitor bank (AC-6b))。We welcome the users to choose for usage。
We welcome the users to choose for usage。
Product features:
Main circuit
? The vacuum switch tube adopts products of domestic well-known manufacturers. They have matured technology, reliable quality and good market credit.
? The main circuit adopts a shape frame structure as a whole,with good rigidity, high dielectric strength and good foul-resistance。?
? 630A current grade uses double moving end jointing of end surface and conductive clip, with low resistance, low temperature rise and higher reliability。
? The conductive bar has good appearance and durability, so it is user-friendly。
Electromagnetic system
? Options of permanent magnetic mechanism or traditional electromagnetic mechanism are available
? Built-in large capacity sealed auxiliary switch ,this can greatly improve the reliability of the auxiliary switch and it can be used safely。
? It can optimize the movement structure, reduce the coil starting power and holding power, thus it has low temperature rise, long service life and high reliability。
Movement structure
? The spindle uses self-aligning bearings, with flexible support, the load-carrying capability is seizure-free, axial movement is small, thus the movement performance and consistency are improved。
? The movement ends use the secondary guiding mechanism to ensure the axial movement coaxiality of conductive pole in the vacuum tube。The reasonable action mechanism,to ensure that improves the performance and reliability of the contactor，in addition, this makes three-phase synchronization and resilience indexes better than the similar products。
? It has enhanced the contact pressure of the main contact and improved electrical properties and movement characteristics. The indexes are superior to other similar products。
The mechanical self-containing equipment has a style of its own, with reasonable structure and it is more reliable for use。
? Easy use and maintenance
? Ontology of product can be installed using horizontal or suspended, convenient installation holes are hanging installation design 。
?Control circuit terminals have function flags for preventing wiring errors. The control terminal block positions can be set according to users' requirements to facilitate wiring. Number of auxiliary contacts can be combined according to the usage requirements。
