Secondary distribution switchgear is being used on the medium voltage side of MV/LV transformer substations (compact transformer substations with concrete or metallic enclosures, purposefully built transformer substations, junction points), for the supply of public buildings (hospitals, office buildings, residential areas, stadiums, airports, supermarkets) and industrial units (refineries, cement factories, shipyards), photovoltaic and wind power stations.
Electroalfa produces switchgear for secondary distribution of the S2490_xx type. This is indoor gear, in metallic cabinet, with a simple bar system, extensible and generally used in medium voltage secondary distribution systems of up to 24KV, rated current in continuous operation of maximum 630A and rated short-time withstand current of maximum 20KA/ 1s.
This type of switchgear resists to the action of the internal electric arc, with a classification index of IAC AFLR 20KA/ 1s. The switchgear ensures the continuity of the service according to the standard classification LSC2B. From the point of view of compartments, the classification of this gear is PI. The equipment are made in compliance with the European Standard SR EN 62271-200 and have been tested in the ICMET labs, with fully compliant results for this type of full tests. The switchgear from the range of P2490_xx show the following advantages easy installation, safe and simple use, safety of the operating personnel, compact, extensible, certified quality, SCADA integrated, optimum price – quality ratio. We ensure consulting for the clients to choose the best technical solutions for each particular application.
Apart from the delivery of the switchgear, Electroalfa can deliver services of: mounting, testing, set up of parameters, commissioning and technical assistance. Furthermore, we offer training services for the operating and maintenance personnel of the client. Electroalfa can provide maintenance services for the entire lifetime of the delivered products.
The main uses of the secondary distribution switchgear are in the compact transformation stations and connection points. The power supply has been lately ensured increasingly by means of compact trafo stations, solutions that offer advantages from the point of view of customizing and module creating the investments, but also a way to shorten the time to finalize the investment.
Compliant with the technical standards of nationwide power distribution companies such as CEZ Group, E.ON Group, Electrica Group (area distribution operators).
