Introduction
Our SC(B) series epoxy resin cast dry transformer is cast under vacuum with thin insulating bands automatically.
The core is made of a high-permeable grain-orientated silicon sheet and cast with imported epoxy resin.
The coil is reinforced with glass fiber and cast under vacuum with filler epoxy resin. It has good mechanical properties, is free of crack and inner bubble, and has a low local discharge, high reliability, and long service life.

The high and low-voltage systems are cast under vacuum, thus the coil will not absorb moisture, the clamps of the core are subjected to corrosion-resistant treatment and it may run under high temperature or other serious environments.
