Dry-type air-core reactor

The invention discloses a dry-type air-core reactor. The outside of an electromagnetic wire thin film wrapping is secondly wrapped with a layer of non-woven fabric; then a layer of F498 high-performance weather-resistant elastic glue is wrapped, so that the non-woven fabric and the F498 high-performance weather-resistant elastic glue form a dense protective layer; an epoxy pad is arranged on a lower conductive arm; the electromagnetic wire is wound upward from the upper end surface of the epoxy pad; and a gap is arranged between the electromagnetic wire and the lower end surface of an upper conductive arm to form end insulation. The dry-type air-core reactor can be operated outdoors for more than 20 years, can withstand -40 degrees Celsius to 150 degrees Celsius, and can play a good role in waterproofing; the curing time is short; the glass transition temperature is great than or equal to 130 degrees Celsius; the tensile strength is great than or equal to 10 MPa; the elongation is great than or equal to 180%;
