The 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 food 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.
·Flame retardancy, explosion-proof and no environmental contamination.
·Gas duct is embedded inside it to enhance the radiation power and over-load capacity.
·Low loss and low noise.
·It highly withstands short-circuit and lightning impact.
·Small in volume, light in weight, safe in running and free of maintenance.
