Аbout us – ELPROM TRAFO
Contemporary automated lines cut the steel sheets delivered in rolls longitudinally and transversally. We are on the market since The optimal design of the windings and employment of most contemporary technology, the optimal selected cooling ducts, properly dimensioned insulation, effective tightening in radial and axial direction result in a high electrical, thermal and dynamic withstand capability according to the requirements of IEC.
China for transformer China transformer kva rating China transformer. Dial type – thermometer with alarm contacts over kVA. The neutral terminal of the LV 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. At the bottom the walls are welded to the tank bottom. We also have another advantage — the especially for us designed software for optimal design of transformers.
These include temperature rise test and lightning impulse test. Rating plate and diagram 4.
The inner parts of the core and coil assembly are coated by an oil resistant enamel. Nowadays we have control laboratories for incoming, current and outgoing control of the materials, trago in the production, as well as testing laboratory for routine and type testing of the transformers.
The quality procedures, according to ISO Oil filling venting plug The active part is lifted along with the cover by the lifting eyes situated on it.

Thus a sufficient thickness of the protective coating of min. Axial bolts do the axial tightening of the windings. China dry transformer kva China transformer w China transformer kva toroid.
The outer surfaces are coated by several layers of anti corrosion primer and finished by high quality alkyd enamel. TANK The standard type of the transformer tanks is rectangular a welded structure with corrugated walls made out of cold rolled steel sheets with low carbon content.
Conservator for TM series We have 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. High quality of the welding seams is guaranteed by tests with penetrating agents in a special test field and by testing with over pressure of 40 kPa. Lifting lugs on tank cover Dehydrating breather for TM series Thus it remains stable during transportation.
The windings are of cylindrical type situated concentrically on the core limbs. Special epoxy resin bushing and plug-in cable connector at the HV side Elastimold system optional.
The active part is fixed to the tank cover and is supported by the tank bottom. You, our customers know well that without solid foundation and clear goals there is no development, and we have both. For more than 10 years now the plant has an established and certified quality management system acc.
The voltage is regulated at the HV side by means of an off-load tap-changer when the transformer is de-energized.
We have a developed and introduced automated system for management of the purchase orders, management system for the technical documentations and management system of the material base of the plant. We can now shorten the production period to a maximum and this elpeom — spare your time.
For each rated power we offer different series, depending on the no-load and load losses. The leads from the HV winding are insulated with thick insulation paper layer elproom insulation tubes and press board.

Oil-draining and sampling valve DIN 9. The maximum production capacity of the plant has been reached before the end of the past century — 10 pieces of transformers are being ttafo annually. The thickness of the coating is increased elprmo on the operational climatic conditions. These are performed upon special request of the customer. The off-load tap-changer is situated vertically between two adjacent phases. The plant introduces a good working system, organized and maintained by high quality experts.
In the upper part the walls are welded to a flange frame to which the tank cover is bolted. Type tests are performed on each transformer traco. Each coat is dried up in electric ovens. This is our path through the years — a path of tradition and continuous renewal. The HV winding is a multi-layer one for the lower ratings and two- elpeom four-section multi-layer, block-coils or continuously wound disk winding for the higher ratings.
