Exterior disconnect switch / high-voltage / horizontal - max. 245 kV, 20 - 40 kA | CSH, CSH-B
The Southern States CSH and CSH-B horizontal interrupter circuit switchers are ideally suited for transformer protection providing up to 40kA primary fault clearing capabiltiy and 4kA secondary through fault clearing capability. All circuit making and breaking operations are accomplished in SF6, eliminating open air arcs. The horizontal interrupter circuit switcher is available with (Model CSH-B) or without (Model CSH) an integral vertical break switch.The design of the CSH and CSH-B is extremely versatile and can be mounted in most any orientation including horizontal upright, vertical, and underhung positions. It can also be designed to mount on a Southern States supplied support structure or for mounting on a customer supplied or existing structure. The CSH-B is also ideal for mobile applications and can be supplied with composite interrupters that can be shipped pressurized.
In addition to transformer protection, the CSH and CSH-B can be used for line dropping, loop splitting, or as a series capacitor/reactor bypass switch.
