Our SC(B) series epoxy resin cast dry transformer is cast under vacuum with thin insulating bands automatically. The core is made of high permeable grain orientated silicon sheet and cast with imported epoxy resin. Thanks to advanced technology, quality raw materials, scientific management , and perfect inspection means , our products have the following features.
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 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 core are subjected to corrosion resistant treatment. The insulating materials in the coil such as glass fiber are self extinguishing and they will not cause fire by the arc resulted from short circuit . The resin will not generate toxic or harmful gas under high temperature.
