LV terminals: normal arrangement top, rear Special version: Bottom available on request at extra charge.
HV Terminals: Variable arrangements, for optimal station design HV tapping links on low voltage side for adjustment to system conditions, reconnect able in de-energized state.
Cross-flow fans: permitting a 50% increase in the rated power.
Temperature monitoring: By PTC thermistor detectors in the LV winding.
Pain finish on steel part: Multiple coating RAL 5009. On request Two component varnish or hot-dip galvanizing (for particularly aggressive environments).
Ambient class E2: Climatic category C2 (if the transformer is installed outdoors, degree of protection IP 23 must be assured).
Three leg core: made of grain-oriented low-loss electro lamination insulated on both sides.
Resilient spacers: To insulate core and windings from mechanical vibrations. Resulting in low noise emissions.
HV winding: consisting of vacuum potted single foil type aluminum coils.
LV winding: Made of aluminum strip turns firmly glued together by means of insulating sheet wrapper material.
Insulation mixture of epoxy resin and quartz powder:
Makes the transformer maintenance free , moisture-proof, tropicalized, flame-resistant and self-extinguishing.
Clamping frame and truck: Rollers can be swung around for lengthways of sideways travel.
