Since epoxy resin is a non-flammable, flame-retardant, self-extinguishing solid insulating material, safe and clean, epoxy resin cast dry-type transformers are oil-free, non-flammable, and have low operating loss, strong short-circuit resistance, less maintenance work, high working efficiency, small volume and low noise. It is often used in places with high performance requirements such as fire prevention and explosion protection, and has the following practical characteristics: 1.It is safe, fireproof, pollution-free, and can be directly operated in the load center; 2.High mechanical strength, strong short-circuit resistance, small partial discharge, good thermal stability, high reliability and long service life; 3.Low loss, low noise, obvious energy saving effect, maintenance-free; 4.Good heat dissipation performance, strong overload capacity, and capacity operation can be increased when forced air cooling; 5.Good moisture resistance, adapt to high humidity and other harsh environments; 6.Dry-type transformers Using intelligent signal temperature control system, it can automatically detect and display the respective operating temperatures of the three-phase windings, can automatically start and stop the fan, and have functions such as alarms and trips; 7.Small size, light weight, less space and low installation cost.
