The dry-type transformer consists of an iron core composed of silicon steel sheets and a coil cast with epoxy resin. An insulating cylinder is placed between the high and low coils to increase electrical insulation, and the coils are supported and restrained by a pad.
Because epoxy resin is flame retardant, flame retardant, self-extinguishing solid insulating material, that is, safe and clean. With oil-free, inflammable, low operating loss, outstanding disaster prevention ability, it is widely used in high-rise buildings, airports, wharfs, power plants, residential areas or complete substations and other places.
Resin-insulated dry-type transformers are safe, non-flammable, fireproof, and pollution-free. It can be directly installed in the load center, maintenance-free, easy to install, low overall operating cost, low loss, good moisture-proof performance, can operate normally under 100% humidity, and can be put into operation after shutdown without pre-drying. Low partial discharge, low noise, strong heat dissipation capacity, 120% rated load operation under forced air cooling. Equipped with a complete temperature protection and control system, it provides a reliable guarantee for the safe operation of the transformer with high reliability.
Main material and characteristics: Class F coil insulated copper wire as conductor, glass fiber and epoxy resin composite materials for insulation, its coefficient of expansion similar to the copper conductor.with good impact resistance, temperature changes, crack resistance. Glass fiber and epoxy resin constituent all have self-extinguishing, it does not continue to burn, it does not produce toxic gases and pollute the environment.Epoxy resin has good insulating properties, particularly suitable for the production of high-voltage level
Manufacturing process: The winding wound on the high-accuracy winding machine, when winding pave cast grass fibre around the external and internal of the winding, there be armed air passage for transformer of large ca Then dry it in vacuum.The whole casting and solidifying process is performed according to the pi curve of casting control terminal, which transferred through computer network by process department every process can be monitored momentarily and adjusted for the various surroundings. The precise process ensures free bubble and free hole of winding.
