M FAULT INiERRUPiEH Kyle's VFI padmounted switchgear provides a simple, economical approach to switching and protection requirements for 15, 25, and 35kV underground systems. The modular design of VFI Vacuum Fault Interrupter switchgear allows the switching system to be tailored to specific requirements without the high cost of custom construction. The VFI resettable breaker mechanism allows immediate service restoration, eliminating the added downtime and expenses associated with changing out conventional fuses. VFI padmounted switchgear is versatile in application. It is suited for utility and commercial/industrial requirements, and is easily adaptable to standardized distribution systems. VFI switchgear is a product of Cooper Power Systems, proven by years of continuous field experience. Deadironf Construction For Added Safety The deadfront construction of VFI padmounted switchgear offers a safety factor for utility personnel and the general public. Inside, all terminators are covered with insulating rubber. All internal parts are completely sealed in an insulating medium to reduce maintenance and eliminate the problems of moisture, dirt, and wildlife commonly associated with air-insulated switchgear. In addition, the VFI can be used in locations where air-insulated switchgear cannot, such as flood areas or high-contaminant industrial sites. Vacuum Technology Cooper Power Systems' Kyle° Distribution switchgear products incorporate vacuum technologies which have advanced the durability and extended the application base for vacuum products. Kyle vacuum interrupters employ axial-magnetic field contacts which keep the arc in an easier- to-interrupt diffuse mode, resulting in less power in the arc that needs to be dissipated. Furthermore, Kyle's patented design uses the entire contact surface, resulting in far less contact erosion and the longest life of any vacuum interrupter in the industry.
