Horizontal CSH type

 The CSH, CSH-B are designed to provide a very compact and reliable solution with fault interrupting capability, particularly for transformer bays. They can replace a quick-whip disconnector to reach a fault clearing / fault making capability. CSH is a horizontal switcher, that can be coupled with a vertical break disconnector (CSH-B) for a visible gap opening. In this case, both equipments are operated by a single mechanism, ensuring an error-free switching sequence. The CSH series has the remarkable feature to adapt to a variety of phase-spacing, and reduce the height of the bay. Therefore, it is ideal for mobile power substation.

Both types are built around single gap SF6 puffer interrupters, which reliability has been proven over years.
