DESCRIPTION The ATR is a three-insulator double center break, outdoor, air disconnect switch con- structed primarily of aluminum; available in ratings from 145kV through 550kV maximum (138kV through 500kV nominal) from 2000 to 5500 continuous amperes. This unique design incorporates triple insulator rotation for better weight distribution along with our “tried and true” center break blade contact assembly found on our AGCH5 unit. APPLICATION The ATR is commonly used in three-phase line or substation applications such as trans- former or line disconnecting, breaker isolat- ing, bypassing or bus sectionalizing. Opera- tion of the ATR may be accomplished by either manual control or by motor operator.

TESTING The ATR has been extensively tested to meet or exceed current ANSI standards. A comprehensive test brochure is available outlining electrical and mechanical design test conducted on the ATR .
