Product Description
Product Structure
Winding: Low-voltage coil is single-layer or multi-layer cylindrical structure, which is made of paper-wrapped oxygen-free copper flat wire or copper foil. High-voltage coil is made of multi-layer cylindrical structure and polyester enamelled copper wire or paper-wrapped copper wire. It has the characteristics of good mechanical strength and short-circuit resistance. Inter-layer insulation is made of DLZ-0.08 insulating point adhesive paper. After the coil is wrapped, it can be dried through the body. The two adjacent layers are firmly pasted to enhance the mechanical strength of the coil.
Iron core
The core is Planar stacked iron core and the core is cold rolled non-oriented electrical steel strip with high magnetic induction, and 450 inclined seam is used to minimize the magneto-resistance, no-load loss and no-load current. The structure has three-phase three-column and three-phase five-column.
