DESCRIPTION The AGCH5 is an outdoor, group-operated side opening two insulator, air disconnect switch with both insulators rotating during operation. The AGCH5 is constructed primar- ily of aluminum and is available in ratings from 8.3kV through 362 kV maximum (7.5kV through 345kV nominal) and 1200 through 6000 continuous amperes. The center break is the easiest operating of all group-operated switches. Mounted horizontal upright or underhung, the blades lift no weight during operation. Mounted vertically, the blades counterbalance each other during operation.

APPLICATION The AGCH5 is commonly used in three- phase line or substation applications such as transformer or line disconnecting, breaker isolating, bypassing or bus sectionalizing. Operation of the AGCH5 may be accom- plished by either manual control or by motor operator. TESTING The AGCH5 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 AGCH5 .
