Product Description
Disconnector for 220kV Substation

These disconnectors are , no load switching devices
which physically isolate the lines. They are designed for
horizontal outdoor application and can also be designed
for vertical installation. For earthing and closing of
switchyard portions of the installation, the earthing
switches are provided on disconnector. If required.
The following documents were referred to during the preparation of this specification. In case of conflict, the provisions of this specification shall take precedence.IEC 129:1975: Alternating Current Disconnectors (Isolators) and Earthing SwitchesIEC 60694:2002: Common Specifications for High Voltage Switchgear and ControlgearBS 729: Hot dip galvanized coating on iron and steel articlesIEC62271-102Isolator (Disconnector) - a mechanical switching device which provides, in the open position, an isolating distance in accordance with Electrical Safety requirements.SERVICE CONDITIONSThe isolator shall be suitable for continuous operation outdoors in tropical areas at altitudes of up to 2200m above sea level, humidities of up to 90%, average ambient temperature of +30ºC with a minimum of -1ºC and a maximum of +40ºC and heavy saline conditions along the coast.4.2.
