Winding Enameled Wires Used For Dry-type transformers
Winding Enameled Wires used for Dry-type transformers which are widely used in local lighting, high-rise buildings, airports, terminal CNC machinery equipment and other places. Simply put, dry-type transformers refer to transformers whose cores and windings are not immersed in insulating oil.
Dry-type transformer is mainly composed of an iron core composed of silicon steel sheets and a coil made of epoxy resin. An insulating tube is placed between the high and low voltage coils to increase electrical insulation, and the coil is supported and constrained by a spacer. Loose performance.
Construction performance:
¢ÅSolid insulation encapsulated winding
¢ÆNo enveloping winding
Winding: Among the two windings, the higher voltage is the high voltage winding, and the lower is the low voltage winding.
From the relative position of the high and low voltage windings, the high voltage can be divided into concentric and overlapping types.
The concentric winding is simple and convenient to manufacture, and this structure is adopted.
Overlap type, mainly used for special transformers.
