Line Tension Disconnect Switch

When you need a switch installed directly into the line, the Chance ALTD Line Tension Disconnect is the answer….. The ALTD is rated 38kV 200kV BIL 900A and 600A for non load break applications and 600A for load break applications with its built in Arc Chutes. The arc chute interrupter is rated for interruption of magnetizing current, line charging current, cable charging current and capacitor switching. The extension link/adapter option allows for mounting on clamp-top insulators. Also available is the ATC1343 PG terminal option which makes this switch suitable for a wide range of applications.

Application
The Chance Line Tension Disconnect switches are singlephase hookstick operated for manual switching of de-energized or parallel circuits of overhead lines on an electrical distribution system of 15 through 38kV, 200kV BIL. They are installed directly into the line. Rated for 600 and 900 amperes continuous current, the ALTD may be applied wherever a disconnect switch is desirable for line sectionalizing. A properly rated ALTD switch should be selected for each installation with consideration to continuous current, BIL and rated voltage.

The ALTD also can be equipped with a load-breaking interrupter or used with a portable Loadbreak tool for load breaking.

Operation
All Chance ALTD disconnect switches include galvanized steel Loadbreak hooks for use with a portable Loadbreak tool. To open the switch under load, use an approved Loadbreak tool
or device designated for use with this type of switch.

For easy opening and ice-breaking action, the pull ring activates the latch as a pry-out lever. The hook portion of the contact casting coordinates with the blade latch for positive closure.
