Substations - Import export

Substations are transformer or distribution centers made of sheet steel in desired dimensions. They are suitable for use of all types of MV switchgears and LV panels. They are manufactured in the requirement number of sections and doors according to the project design. Strong construction made of sheet steel and profiles is painted with electrostatic powder paint or liquid paint for high corrosion resistance. In order to prevent the strong solar radiation in hot summer, the shell can be equipped with heat insulation material with low thermal conductivity, the most used fillers are: rock wool board, polystyrene foam, etc. Modular design in requested depth, width and length, in average 4 times lighter than a concrete version along with easy transport and commissioning are just some of the advantages of this solution. Compact substations are suitable for residential quarters, urban public utilities, renewable power plants, power distribution etc

The compact transformer substations provide connections between industrial or residential consumers and the medium voltage network. Electroalfa produces prefab transformation stations of the MT/JT type Alfa Power, in a varied range of types and sizes, in standard production, but also derived products, adapted to the required application.To meet the market’s demands we design compact transformer prefabricated substations with concrete or metal enclosures with standard ranges from 160kVA to 1600 kVA (upon request, up to 2500KVA) with indoor or outdoor access.

Tavrida Electric recloser can be used to quickly build costeffective unmanned structure mounted outdoor substation. Provides full protection and automation functionality required at the substation.

Hotdip galvanized steel mounting kit for Rec15/25 installation at outdoor substation. It can be installed at newly erected substation or as a retrofit for old outdoor circuit breakers.

Adoption of SF6 alternative gases increases the maintenance and analysis burden on utility staff, requiring multiple analysers to fulfil test and analysis procedures. This requires increased levels of capital budget; increased time to undertake maintenance tasks; resulting in greater inefficiencies onsite. The EMT Zerowaste Rapide Eco+ solves this problem by fulfilling all measurement requirements in one, simple, portable device. Built on the existing market leading EMT Rapide+ platform, Eco+ is the world’s first 4in1 analyser for the measurement of SF6, Novec 4710, Novec 5110 and Dry Air insulating gas applications.

AFS corona generators are THE standard for foil extrusion and the packaging industry. It is not without reason that the largest machine manufacturers opt for AFS as their standard equipment. The initial investment cost of any system is only part of the total running costs over the life time of a machine. Reliability and high efficiency results in minimum downtime and loss of production. The failure of a corona treater system can result in a total plant shutdown costing far more than the difference in price between a low quality and higher quality treatment system.

Nomex-Kapton -Nomex (NKN) tubes are stator slot liner insulators produced with a low thickness of only 0,16 mm without overlaps. This means an improved thermal management inside the stator slot, less overheating inside, higher torque and motor efficiency, more space for copper hairpins & I-Pins, improved dielectric strength. Reducing the thickness of slot insulator and improving dielectric & thermal insulation is a key stone to improve motor efficiency and performance in terms of: 1. Improving thermal conductivity and reducing thermal resistance 2. Reducing the temperature of the copper hairpin hotspot 3. By reducing the insulator volume because of a reduced thickness and lack of overlaps; this means that the amount of copper inside the slot can be increased, improving motor performance 4. Reducing phase resistance Nomex and Kapton are DuPont registered trademarks
