Technical Features
STANDARD
The transformers are built in accordance with IEC 726 standards.
CORE
The core is built up of cold rollled oriented grain steel sheet with low specific losses, insulated on both sides by a thin inorganic coating (Carlyte). The sheets composing the core are cut at 45 degrees. Uniform pressing, stiffnes and solidity of the columns assure a low noise level.
MEDIUM VOLTAGE WINDINGS
The high voltage are made of electrolitic aluminium conductors (wire or foil strip depending upon power and voltage requirements). It is possible to produce copper windings. The windings are inglobed under vacuum in class F epoxidic resin. The accuracy of execution of these processes allows the obtainement of windings free from partial discharges.
LOW VOLTAGE WINDINGS
The low voltage windings are made of strip or foil (copper or aluminium conductor depending upon power and voltage requirements). Class H insulating material is used.
STANDARD ACCESSORIES
Skid under base or truck with bidirectional wheels; Lifting lugs; Earthing terminal.
OPTIONAL ACCESSORIES
Thermometer dial type whith electric contacts; Temperature monitoring unit without display; Temperature monitoring unit with display; Cubicle IP 315 or other; Forced ventilation system.
TEST
All transformers are singulary tested with routine test, according to standard IEC 726. Upon request the following type test can be carried out; temperature.
