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.
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 and it may run under high temperature or other serious environments.
Flame retardancy, explosion-proof and no environmental contamination. 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. Gas duct is embedded inside it to enhance the radiation power and over-load capacity. Low loss and low noise. The core is lapped with 45 full-miter and the step-type lamination effectively improves distribution of magnetic flux at core corners, and greatly reduces the no-load loss and the nose level. It highly withstands short-circuit and lightning impact. Small in volume, light in weight, safe in running and free of maintenance. As per users’ requirements the transformer may be provided with casing and blower fan.

The SC(B) series dry-type transformer is cast under vacuum with thin insulating bands. The core is constructed using high-permeable grain-orientated silicon sheets and encapsulated with imported epoxy resin to ensure durability and minimal loss.
Both high-voltage and low-voltage systems are cast under vacuum, rendering the coil moisture-resistant. Furthermore, the core clamps undergo a corrosion-resistant treatment, ensuring reliable operation in high temperatures and other severe environments.
Yes, the transformer features self-extinguishing flame retardancy, is explosion-proof, and produces no environmental contamination. The epoxy resin does not emit harmful or toxic gases even under extremely high temperatures.
The core utilizes a 45-degree full-miter step-type lamination structure. This optimized design improves magnetic flux distribution at the core corners, significantly reducing both no-load loss and the overall noise level.
The SC(B) series dry-type transformer supports a wide range of rated primary voltages, including 3.3 KV, 6.0 KV, 10 KV, 15 KV, 22 KV, 33 KV, and up to 36 KV, with a tapping range of ± 2 X 2.5%.
No, the transformer is designed to be virtually maintenance-free. It features a compact volume, lightweight construction, robust short-circuit resistance, and excellent lightning impact protection for long-term safe operation.
