The "GV Series" Vacuum Interrupters (VIs) are designed to suite the requirements of the users for various applications. These VI designs are being manufactured in the state of art processing facility with the unique selling parameters (USPs). The USPs of Vis are validated to enhance the performance &reliability of Vis as well as the switchgears.
The clinically clean manufacturing & testing facility at "Vijai Electricals Ltd.," in India is comprising of world class brands of Vacuum Furnaces, Clean Room of 10001 100 class and other processing, testing equipments. The VI specifications varies from rated voltage 690 V to 52 kY, rated normal current 400 Ato 3 150 A, Short Circuit breaking 4 kAto 44 kA.The application of Vis encompasses Conventional Circuit breakers, Vacuum Contactors, Auto Reclosers, RMUs etc.
USPs
Mechanically Strong Construction.
No external insulation on VI Such as Silicon rubberl Polyurethane.
EPDM Sleeve facilitates closer interphase distance inVCB.
Rated line to line voltage can be extended if required to the next standard rating.
Rated short circuit current can be extended if required to the next standard rating.
Best performance &Higher reliability due to above special Design features.
