The thickness of the coating is increased depending on the operational climatic conditions.

Buchholz relay over kVA We also have another advantage — the especially for us designed software for optimal design of transformers. Contemporary lines for automatic corrugation and plasma welding produce the tank walls. 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.

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. Each coat is dried up in electric ovens. The windings are of cylindrical type situated concentrically on the core limbs.

Off-load tap-changer driving mechanism 5. The active part is lifted along with the cover by the lifting eyes situated on it.

We can now shorten the production period to a maximum and this way — spare your time. 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.

Dial type – thermometer with alarm contacts over kVA. Using the scroll is also considered to be a consent! The fitting elements bolts, nuts, washers etc. 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.

The inner parts of the core and coil assembly are coated by an oil resistant enamel. At the bottom the walls are welded to the tank bottom. These are performed upon special request of the customer.

The outer surfaces are coated by several layers of anti corrosion primer and finished by high quality alkyd enamel. Not exactly what you want? 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.

Special epoxy resin bushing and plug-in cable connector at the HV side Elastimold system optional. 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. The transport carriage with wheels is fitted to the tank bottom allowing bi-directional movement of the transformer.

The off-load tap-changer is situated vertically between two adjacent phases. Lifting lugs on tank cover They have an insulation of cable paper or enamel resistant to hot transformer oil. The leads from the HV winding are insulated with thick insulation paper layer and insulation tubes and press board.

Axial bolts do the axial tightening of the windings. Type tests are performed on each transformer type.

One decade later the plant achieves significant development, it is renewed technologically, expands and the production range is extended. In the upper part the walls are welded to a flange frame to which the tank cover is bolted. We have a developed and introduced automated system for management of the purchase orders, management system for dlprom technical documentations and management system of the material base of the plant. China dry transformer kva China transformer w China transformer elpro, toroid.

These include temperature yrafo test and lightning impulse test. The plant introduces a good working system, organized and maintained by high quality experts. Oil filling venting plug Conservator for TM series 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. China for transformer China transformer kva rating China transformer.

Dehydrating breather for TM series For each rated power we offer different series, depending on the no-load and load losses. The active part is fixed to the tank cover and is supported by the tank bottom. The voltage is regulated at the HV side by means of an off-load tap-changer when the transformer is de-energized.

Contemporary automated lines cut the steel sheets delivered in rolls longitudinally and transversally.
