Brief introduction
1. three phase dry type electrical power transformer is cast under vacuum with thin insulating bands automatically.
2. The coil is reinforced with glass fiber and cast under vacuum with filler epoxy resin.
3. three phase dry type electrical power transformer has good mechanical properties, is free of crack and has low local discharge, high reliability, and long service life.
4. three phase dry type electrical power transformer is flame retardancy , explosion-proof and no environmental contamination.
5. It's resin will not generate toxic or harmful gas under high temperature.
6. three phase dry type electrical power transformer highly withstands short-circuit and lightning impact.
7. Small in volume, light in weight, safe in running and free of maintenance.
8. As per users’ requirements, 3 phase dry type electrical power transformer may be provided with casing and blower fan.
Features
1. High mechanical strength and strong short circuit resistance ability;
2. Good moisture resistance and run with 90% humidity;
3. Advanced structure, small dimension, light weight and low partial discharge;
4. High insulation level and equal electric field distribution;
5. maintenance free;
6. Run with 140% rated load under forced air cooling;
7. Fireproof, explosion-proof, pollution-free and low-noise and able to be directly installed in the load center.
Routine Tests
a) Measurement of winding resistance
b) Measurement of voltage ratio and check of phase displacement
c) Measurement of short-circuit impedance and load loss
d) Measurement of no-load loss and current.
e) Dielectric routine tests.
f) Tests on on-load tap-changers, where appropriate
