Application

SCR9,SCR10 series resin-insulated coil dry-type power transformers

In the high-voltage and high-volume dry-type transformers now produced by cast process at home and aborad, stress,minute cracks,and spots whre resin has not fully permeated may exist within the winding.And coil dry-type transformers can completely make up for the above deficiencies,with the characteristics fo energy-saying,extremely high mechanical strength and electric strength, strong resistance to short circuit,never crackong winding,explosive-proof,high overload capacity,short productiong cycle,high stability upon cold and hot impact,etc.,especially suitable for models of high-voltage,high-volume dry-type transformers in flammable areas.

SCR9,SCB9,SC10 series resin-insulated coil dry-type power transformers

his series of products are characterized by cast windings filled with chopped strand which take the shape of a segmented cylinder. Within the windings axial airways are designed to improve heat dissipating. Scientific cast mold process ensures that resin can fully permeate into the interturn,interlayer, and intersegmental parts, and consequently guarantees the insulation strength of products and minor amount of partial discharge.

How to prevent crackong of resin casts,restrain generation of air bubbles in casts,and reduce partial discharge to the lowest level represents key manufacturing technology of resin cast dry-type transformers,the stydy of which has been the important task of many dry-type transformer manufacturers at home and abroad.

This company has succcessfully rsolved the extremely difficuly problems through repeated practices and frequent physical and chemical experiments,putting forward the thin-insulated vacuum cast products filled with chopped strand whose tensile strength is improved to 170N/mm2 and bending strength to 220N/mm2. The mechanical performance of resin composites has been enhanced on a whole.

The unique characteristics of the SC(B)9,SC(B)10 series resin cast thin-insulated dry-type power transformers are as follows:

strengthen the heat dissipating ability of winding.

Windings are strengthened with filament mats so that windings?mechanical strength is improved,products?short-circuit resisting capability is enhanced,and the problem of cracking casts is successfully resolved.

Special processing is applied to windings to greatly reduce partial discharge within windings and improve the electric strength of windings.

Low-voltage windings adopt foil structure to reduce magnetic leakage at the top and improve short-circuit resisting capability.
