Contemporary lines for automatic corrugation and plasma welding produce the tank walls. Special epoxy resin bushing and plug-in cable connector at the HV side Elastimold system optional.

For each rated power we offer different series, depending on the no-load and load losses. The fitting elements bolts, nuts, washers etc. At the bottom the walls are welded to the tank bottom. Dehydrating breather for TM series These include temperature rise test and lightning impulse test. Oil filling venting plug Ellrom can now shorten the production period to a maximum and this way — spare your time.

Nowadays we have control laboratories for incoming, current and outgoing control of the eoprom, used in the production, grafo well as testing laboratory for routine and type testing of the transformers. Oil-draining and sampling valve DIN 9. Lifting lugs on tank cover We also have another advantage — the especially for us designed software for optimal design of transformers. The active part is lifted along with the cover by the lifting eyes situated on it.


Axial bolts do the axial tightening of the windings.

Our production is maximally extended — we manufacture the full range of oil immersed distribution transformers with rated power from 25kVA up to 10 kVA. Contemporary automated lines cut the steel sheets delivered in rolls longitudinally and transversally. Dial type ttrafo thermometer with alarm contacts over ttrafo.

The maximum production capacity of the plant has been reached before the end of the past century — 10 pieces of transformers are being manufactured annually. The neutral terminal of the Elprpm winding for all the transformers is brought out on the transformer cover through a separate bushing that is designed for the full rated current and is insulated for the highest voltage of the LV system. Not exactly what you want? Welding is done in protective atmosphere Ar-CO2.

China for transformer China transformer kva rating China transformer. We slprom special design and technological departments, thereby the production cycle becomes fully closed — from the design of the transformer to its assembly, in accordance with the requirements of the end customer and every related national and international standard.

We are on the market since Buchholz relay over kVA The thickness of the coating is increased depending on the operational climatic conditions. Special tests are performed on each transformer type including short-circuit test and noise level measurement. Conservator for TM series The quality procedures, according to ISO The transport carriage with wheels is fitted to the tank bottom allowing bi-directional movement of the transformer.

This is our path through the years — a path of tradition and continuous renewal. The windings are of cylindrical type situated concentrically on the core limbs.

Upon request the tank and cover are hot-dip zinc galvanized. The LV winding is situated at the core limb and is foil cylindrical type made out of profiled section copper for the ratings including kVA and out of copper foil for ratings kVA and above.
