Product Description
11kv 125kVA Dry Type Power Transformer for Substation by Factory
Product Introduction
Dry-type transformers refer to the serials of transformers whose core and windings are not immersed in the insulating oil .Cooling ways are divided into natural air cooling (AN) and forced air cooling (AF).
When designed with natural air cooling, transformer can be long-term continuously operated at the rated capacity. When designed with forced air cooling, transformer output capacity can be increased. Dry-type transformers are suitable for intermittent overload operation, accident or emergency overload operation;
Due to overload loss and impedance voltage increase largely , the transformer is not in an economical operating state, so it should not be run at continuous overload state for a long-term.
Application
high-rise buildings, commercial centers, city squares, hospitals, schools, airports, railway stations, port terminals, subway, power plants, oil field, chemicals, tunnels and other places.
Features:
Small size, light weight, easy installation, maintenance-free, good economic performance.
Low noise, low loss, good thermal performance, strong overload capability.
Good moisture resistant ( run properly in 95% relative humidity environment)
Small capacity of partial discharge, good insulation properties
High mechanical strength and good thermal stability
Good flame retardant capability, with automatic flameout characteristic, can be installed in the load center.
