SC(B)H15 Type Dry-type Transformer •Main Function And Features 01) Product standard: GB/T10228-2008, GB6450-1996, IEC726 02) Rated voltage: HV: 35, 10 (10.5, 6.3, 6) kV; 0.4kV 03) Insulation level: L175AC35/AC3 LI170AC70/AC3 04) The core is amorphous alloy 05) Low loss and low noise 06) It highly withstands short-circuit and lightning impact 07) Flame retardancy , explosion-proof and no environmental contamination • Introduction To Products 01) Our SC(B)H15 series resin insulation amorphous alloy dry-type transformer is cast under vacuum with thin insulating bands automatically . 02) A model SCBH15 amorphous alloy product adopts a single-frame or three-phase five-legged spiral core. 03) The core is clamped with sheet-formed frame structure and the low-voltage coil is of a foil winding type so as to render a low loss and a high short-circuit withstand. 04) 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. 05) Small in volume, light in weight, safe in running and free of maintenance. 06) It has advanced and rational structure and its overall performances reach international advanced level.
