[0002] Dry-type transformers are widely used in local lighting, high-rise buildings, airports, docks, CNC machinery and equipment and other places. Simply put, dry-type transformers refer to transformers whose cores and windings are not immersed in insulating oil. They are mainly composed of cores made of silicon steel sheets and coils cast with epoxy resin. Insulating cylinders are placed between high and low voltage coils to increase electrical insulation, and the coils are supported and constrained by pads. The fasteners overlapping its components have anti-loosening properties.
