Disconnector: a safety device at the heart of each substation
A disconnector is a switching device which provides, in the open position, an isolating distance in accordance with specified requirements.
A disconnector is also capable of:
Disconnectors are basically safety devices, since their main goal is protecting the staff working in the substations, providing “VISUAL evidence” of circuit opening.
Different models of disconnectors exist, according to the type of connection established within the circuit (horizontal or vertical), the type of break (single or double), the movement of main circuit, etc.
The choice of the right disconnector is influenced by many different factors, usually related to the design of the substation in which it will be installed (rated voltage, availability and cost of the land, type of connection required...). However, familiarity with the use of one type of disconnector rather than another is sometimes the driving factor determining the final choice.
COELME-EGIC can supply all models of disconnectors required by the market, ensuring their maximum reliability, also under the most severe operating conditions (in coastal and/or industrial areas, in geothermal areas, in the presence of ice, at extreme temperatures, in seismic areas...).
All COELME-EGIC disconnectors share the following features:
