drycast resinlow-voltage

ELTAS A.S cast resin dry type transformers are produced up to 20000 kVA with maximum voltage level 36 kV and 250 kV impulse level. TECHNICAL SPECIFICATIONS Low Voltage Coils Foil coil technology is used because of technical advantages in low voltage coils. Copper or aluminium material are used for coils as per the request of the customer. By means of foil coil technology, axial short circuit forces are reduced; prepreg insulation material class F (optionally class H) is used between back beams to control the radial short circuit forces. Coils are subject to tempering process following the winding and resistance to the hardest industrial atmospheric conditions and perfect dielectric characteristics. Low voltage coils can be also manufactured by casting technology under vacuum depending on the request of the customer.
