The thickness of the coating is increased depending on the operational climatic conditions. The HV winding is a multi-layer one for the lower ratings and two- or four-section multi-layer, block-coils or continuously wound disk winding for the higher ratings. Lifting lugs on tank cover We also have another advantage trqfo the especially for us designed software for optimal design of transformers.

Аbout us – ELPROM TRAFO

Thus a sufficient thickness of the protective coating of min. Upon request the tank and cover are hot-dip zinc galvanized. Trafoo plant introduces a good working system, organized and maintained by high quality experts. They have an insulation of cable paper or enamel resistant to hot transformer oil. Rating plate and diagram rtafo. Oil-draining and sampling valve DIN 9.

Conservator for TM series 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.

The trfo are of cylindrical type situated concentrically on the core limbs. The outer surfaces are coated by several layers of anti corrosion primer and finished by high quality alkyd enamel.

Buchholz relay over kVA The active part is fixed to the tank cover and is supported by the tank bottom. 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.

Contemporary lines for automatic corrugation and plasma welding produce the tank walls. We are on the market since 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.

Not exactly what you want? Welding is done in protective atmosphere Ar-CO2. The voltage is regulated at the HV side by means of an off-load tap-changer when the transformer is de-energized. Type tests are performed on each transformer type. The transport carriage with wheels is fitted to the tank bottom allowing bi-directional movement of the transformer.

Special epoxy resin bushing and plug-in cable connector at the HV side Elastimold system optional. You, our customers elprpm well that without solid foundation and clear goals there is no development, and we have both.

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. High quality of the welding seams is guaranteed by tests with penetrating agents trato a special test field and by testing with over pressure of elrpom kPa. 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.

The leads from the HV winding are insulated with thick insulation paper layer and insulation tubes and press board. The fitting elements bolts, nuts, washers etc. At the bottom the walls are welded to the tank bottom. We can now shorten the production period to a maximum and this way — spare your time. Axial bolts do the axial tightening of the windings. For more than 10 years now the plant has an established and certified quality management system acc.

China dry transformer kva China transformer w China transformer kva toroid. Dial type – thermometer with alarm contacts over kVA. Nowadays we have control laboratories for incoming, current and outgoing control of the materials, used in the production, as well as testing laboratory for routine and type testing of the transformers. Off-load tap-changer driving mechanism 5.

ELPROM TRAFO CH Oil Filled Distribution Transformers 25-2500 KVA

Our production is maximally extended — we manufacture the full range of oil immersed distribution transformers with rated power from 25kVA up to 10 kVA. The inner parts of the core and coil assembly are coated by an oil resistant enamel. China for transformer China transformer kva rating China transformer. The quality procedures, according to ISO One decade later the plant achieves significant development, it is renewed technologically, expands and the production range is extended.

Each coat is dried up in electric ovens. Thus it remains stable during transportation. Oil filling venting plug Using the scroll is also considered to be a consent! These include temperature rise test and lightning impulse test. The combinations of LV foil winding and multi layer HV winding results in a significant reduction of the axial electrodynamics forces at short circuit for the high ratings.
