Leprom fitting elements bolts, nuts, washers etc. 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. We can now shorten the production period to a maximum and this way — spare your time. The leads from the HV winding are insulated with thick insulation paper layer and insulation tubes and press board. Buchholz relay over kVA Each coat is dried up in trrafo ovens.

Axial bolts do the axial tightening of the windings. At the bottom the walls are welded to the tank bottom. Type tests are performed on each transformer type. 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.

Contemporary lines for automatic flprom and plasma welding produce the tank walls. They have an insulation of cable paper or enamel resistant to hot transformer oil.

This is our path through the years — a path of tradition and continuous renewal. Lifting lugs on tank cover Dehydrating breather for TM series elprlm 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.

The windings are of cylindrical type situated concentrically on the core limbs. China for transformer China transformer kva rating China transformer. Welding traf done in protective atmosphere Ar-CO2.

Thus it remains stable during transportation.

ELPROM TRAFO CH Oil Filled Distribution Transformers 25-2500 KVA

Traf production is maximally extended — we manufacture the full range of oil immersed distribution transformers with rated power from 25kVA up to 10 kVA. You, our customers know well that without solid foundation and clear goals there is no development, and we have both.

The inner parts of the core and coil assembly are trato by an oil resistant enamel. Using the scroll is also considered to be a consent!

The quality procedures, according to ISO Oil-draining and sampling valve DIN 9. The active part is fixed to the tank cover and is supported by the tank bottom. Conservator for TM series These are performed upon special request of the customer.

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. We also have another advantage — the especially for us designed software for optimal design of transformers. 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.
