AR141 14.4kV, 110kV Porcelain, Delta AR Switch

by CHANCE Utility 

14.4kV, 110kV LIW, 900A, Delta 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.
Refer to the Catalog Numbering System resource below for each configuration option (Positions 4 to 13).
