AR156 34.5kV grounded wye, 150kV Polymer, Inverted AR Switch
Brand: Chance
34.5kV grounded wye, 150kV LIW, 900A, Inverted, Three-Phase Gang Operated Loadbreak Switch.
- The Type AR switches have a clockwise opening and are operable by torsional or reciprocating controls as well a hookstick operation option (full-length down-the-pole control or crossarm-mounted hook stick-operation control). The hookstick operation minimizes installation time, reduces possible vandalism, eliminates control adjustments.
- All three phase switches feature a four-link overtoggle mechanism to assure locked closed blades, mechanical advantage for easier open and close operation, and""snap"" feedback to the operator.
