Good Electrical Performance, Strong Lightning Resistance
Jun 08, 2018

Epoxy resin dry-type transformers use epoxy resin as the insulating material. High- and low-voltage windings are wound with copper tape (foil), epoxy resin is poured and cured in vacuum to form a high-strength glass-steel structure. Insulation class F, H level. Epoxy dry-type transformers have good electrical properties, strong lightning impulse resistance, strong short-circuit resistance, small size and light weight. The temperature display controller can be installed to display and control the operating temperature of the transformer winding to ensure the normal service life of the transformer.

Epoxy resin is a non-flammable, flame-retardant, self-extinguishing solid insulation material, safe and clean. It is also a solid insulation material with reliable insulation and heat dissipation technology that has been proven for over 40 years.

1. All high and low voltage windings are wound with copper tape (foil);

2. The high and low voltage windings are all cast in epoxy vacuum and cured to form a high strength glass fiber structure;

3. High and low voltage windings are equipped with longitudinal ventilation air ducts according to the heat dissipation requirements;

4. The inner and outer surfaces of the coil are reinforced by glass fiber mesh cloth;

5, insulation class F, H level;

6, epoxy resin dry-type transformers small size, light weight. A temperature display controller can be installed on the epoxy resin dry-type transformer to display and control the operating temperature of the transformer winding to ensure the normal service life of the transformer. Its temperature sensor PT100 platinum resistance inserts the low temperature winding to obtain the temperature signal, after the circuit processing on the control board cycle shows each phase winding temperature. It has a temperature setting function, manual / automatic start and stop fan, issued a fault, over-temperature sound and light signal alarm and over-temperature automatic tripping and other functions, with the state's anti-electromagnetic interference capability. At the same time, a smart computer interface is reserved for remote control. Epoxy dry type transformers are equipped with low noise amplitude flow fans, which can reduce the winding temperature after startup, increase the load capacity, and extend the life of the transformer. When forced air cooling is used, the rated capacity can be increased by 40-50%.
