Winding Assembly

Both high- and low-voltage windings are made of copper foil or foil strip and vacuum cast in metal molds as separate concentric cylinders. High-voltage windings are wound using foil strip technology. Multiple layers of polyimide film (180°C system) or DUPONT @MYLAR (155°C system) provide turn insulation. Individual coil sections are wound directly on the inner winding mold and then connected in series by welding.

External molds are assembled and placed in a vacuum chamber. Coils are preheated under high vacuum to remove trapped moisture. A special mixture of epoxy resin and quartz powder flows into the mold through an opening in the molding assembly. After pouring, the molds are cured in a time-temperature process controlled oven. The result is a reliable, vacuum cast winding with an unusually high strength, an essentially void 05

The core clamping brackets are designed to provide an even distribution of clamping forces to the core yokes and legs, and are rigidly braced to reduce sound levels and losses.

Enclosures Withstands the harshest indoor and outdoor environments. Enclosures are suitable for lifting, jacking, rolling or skidding with provisions for lifting the transformer from its base. The standard indoor enclosures are from IP20 to IP54 and NEMA 1, Category C construction. While core and coil technologies have been enhanced to combat caustic and humid environments, Wave Cast transformers are further protected by properly designed enclosures.

Accessories Temperature monitor and fan controller The controller can display the operating temperature of windings, start and shut off the cooling fans and provides alarm/trip signal (normal open voltage-free contact), ensuring effective monitoring and protection of the transformer. The PT100 sensors are inserted into each LV winding to transmit temperature signals, which can be displayed on the controller panel. Main functionality: ●● Set alarms and trip temperature levels ●● Record the maximum temperature in non-volatile memory ●● Send audible over-temperature alarm, alarm signal and trip signal ●● Start and stop fans automatically or manually ●● Provide communication interface (optional)

Cross flow fan The low noise cross flow fan reduces the winding temperature, enhances the overload ability, and prolongs the service life of the transformer. The rated power can be increased by 2540% when forced air-cooling is used.
