25 kV LOADBREAK
BUSHING INSERT

The Hubbell Loadbreak Bushing Insert represents state-of-the-industry design in an All Copper construction. It is designed for installation on transformers or other equipment having a bushing well that meets the requirements of IEEE Standard 386, Fig.3.

PRODUCT FEATURES

1. EPDM insulation - cured with peroxide process. Provides superior stress-relaxation characteristics, assuring long life under high ambient temperature.
2. Interface -conforms to IEEE Standard 386, Figure 5. When a suitable elbow is installed, provides proper creep distance and water-tight joint.
3. Locking groove -conforms to IEEE Standard 386. Mates with elbow locking ring. Red color for 15kV identification.
4. Molded shield -conductive, abrasion resistant 1/8 inch thick shield of peroxide cured EPDM. Three molded tabs provide convenient points for external grounding of the shield.
5. Loadbreak assembly -includes Arc MateTMablative material that produces gas when exposed to the Ioadbreak/Ioadmake switching arc.
6. Pinch-finger contacts -are part of loadbreak assembly which has All Copper current path.
7. Piston assembly -patented concept. Piston movement assists operator under fault-close conditions.
8. Interface -designed to mate with IEEE Standard 386, Figure 3, bushing-well interface.
9. Vented Seating Indicator -molded into insert. Provides positive seating indication and assists in minimizing no load, partial vacuum flashovers.
