Secondary switchgear

medium-voltageair-insulatedpower distribution

The medium voltage switchgear with double bar system is designed for the primary distribution on the medium voltage part of transformation stations from the power distribution systems and combines the new technologies with the existing infrastructure. The medium voltage switchgear with double bar system is an indoor electrical equipment, in metallic compartments cabinet, with insulation in the air, being formed of a vacuum breaker and air bar separator. 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.
