SHARQ-35 series cassette-type switchgears and controlgears for 35 kV
SHARQ-35 series switchgears and controlgears are intended to receive and distribute three-phase AC electric power of 35 kV voltage and 50/60 Hz frequency in grids with insulated neutral or neutral earthed through an arcing ground suppressor.
SHARQ-35 series switchgears and controlgears are used as 35 kV switchgear of 220(110)/35 kV and 35/6(10) kV transformer substations as well as in power distribution substations.
SHARQ-35 series switchgears and controlgears are designed for indoor operation under the following conditions:
- relative air humidity: 98% at +25° С;
- atmosphere category is II according to GOST 15150-69;
- environment: non-explosive, containing no current-conducting dust, aggressive gases and/or vapors in concentration that may damage the insulation and metal.
These switchgears and controlgears can be installed in modular buildings equipped with heating and ventilation systems.
SHARQ-35 series switchgears and controlgears have the following distinctive features:
- wide spacing in the arrangement of the main circuits;
- high quality of assembly;
- sophisticated interlock system ensuring safety of the maintenance personnel;
- design providing easy maintenance.
