Description

Product Overview

This series of transformers is cast with advanced technology, which has high reliability and long service life. It can be added with protective shell according to different protection levels. It is suitable for high-rise buildings, commercial centers, airports, tunnels, chemical plants, nuclear power plants and other important or special environmental places.

Product Characteristics

Energy saving and low operating cost, which is obviously lower than SC (B) 9.
Low noise and high insulation level.
New technologies, new processes and new materials are applied in the design, which is small in size and light in weight.
Low partial discharge, with partial discharge below 5pc, high product reliability.
Beautiful appearance, adopting vacuum pressure casting with filler resin, high surface finish of coil, coil color being natural color of material. The surface is not sprayed, and primary color is still maintained after the end of service life of the transformer.
Reinforced grid is used inside and outside the coil to make the resin grid and wire firmly become a whole, which has high mechanical strength and strong short-circuit resistance.
It adopts resin with filler, making the felt not easy to fly when winding, with combustion heat, and meets the requirements of environmental protection.
