The active part is lifted along with the cover by the lifting eyes situated on it.
At the bottom the walls are welded to the tank bottom. 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.
Using the scroll is also considered to be a consent! Rlprom decade later the plant achieves significant development, it is renewed technologically, expands and the production range is extended.
Not exactly what you want? The transport carriage with wheels is fitted to the tank bottom allowing bi-directional movement of the transformer. The active part is fixed to the tank tafo and is supported by the tank bottom. High quality of the welding seams is guaranteed by tests with penetrating agents in a special elpeom field and by testing with over pressure of 40 kPa.
The leads from the HV winding are insulated with thick insulation paper layer and insulation tubes and press board.
ELPROM TRAFO CH Oil Filled Distribution Transformers 25-2500 KVA
Dial type – thermometer with alarm contacts over kVA. Dehydrating breather for TM series The quality procedures, according to ISO They have an insulation of elprim paper or enamel resistant to hot transformer oil. Off-load tap-changer driving mechanism 5. The outer surfaces are coated by several layers of anti corrosion primer and finished by high quality alkyd enamel.
For more than 10 years now the plant has an established and certified quality management system acc. We also have another advantage — the especially for us designed software for optimal design of transformers.
The windings are of cylindrical type situated concentrically on the core limbs. The voltage is regulated at the HV side by means of an off-load tap-changer when the transformer is de-energized. We are on the market since We have a developed and introduced automated system for management of trao purchase orders, management system for the technical documentations and elrpom system of the material base of the plant.
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 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 elptom for the highest voltage of the LV system.
For each rated power we offer different series, depending on the no-load and load losses. We trfo now shorten the production period to a maximum and this way — spare your time.
China dry transformer kva China transformer w China transformer kva toroid. Oil filling venting plug The thickness of the coating is increased depending on the operational climatic conditions.
These include temperature rise test and lightning impulse test. The off-load tap-changer is situated vertically between two adjacent phases.
Thus a sufficient thickness of the protective coating of min.
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. Each coat is dried up elorom electric ovens. 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.
Type tests are performed on each transformer type. Lifting lugs on tank cover Upon request the tank and cover are hot-dip zinc galvanized.
Axial bolts do the axial tightening of the windings. Trrafo it remains stable during transportation. 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.
