Product Profile:

SCB (10) dry-type transformer is arranged inside the coil axial airway to improve the heat dissipation condition, casting process of science can ensure that the resin fully penetrate into the inter turn and inter layer, between segments to ensure product electrical insulation strength and less Bureau placed (≤5ppc).The characteristics of SC (B) 9 and SC (B) 10 series resin casting thin insulation dry change products made in our company:

1.SCB series dry type transformer reduces the thickness of the package sealing resin, and enhances the heat dissipation ability of the coil.

2.The coil is strengthened with glass fiber felt, which enhances the mechanical strength of the coil and improves the burst resistance of the product.

3.The coil adopts special technology, greatly reduces the local discharge of coil, improves the coil electrical strength.

4. The low voltage coil adopts foil structure, which reduces the magnetic flux leakage at the end, and improves the ability of products to withstand short circuit burst.

 Iron core:

1.Select imported high quality cold rolled silicon steel sheet, low loss.

2.The iron core uses 45 degree full oblique seam structure, the core column uses the insulation belt banding, reduces the noise and the no-load loss

3.The core surface of the insulation resin seal to prevent moisture, rust, clamps and fasteners surface treatment to prevent corrosion.

High voltage winding:

1.Using F insulated copper wire winding glass fiber and epoxy resin composite material as insulation, vacuum pouring

2.The expansion coefficient of glass fiber and epoxy resin composite is similar to that of copper conductor, and it has better impact resistance and crack resistance

3.The pouring resin mixed material can be completely soaked into the coil gap, so that the coil is no bubble, and the coil is placed low

 Low voltage winding:

1.The foil conductor in automatic foil winding, internal welding on the winding machine, argon shielded welding, no external welding process

2.F insulation is used between winding layers, and the back end is cured by resin sealing
