Abstract
An electrical component such as a transformer is encapsulated by placing the transformer in a moulding vessel located in a chamber connected by valves to a vacuum pump, a supply of sulphur hexafluoride, and a supply of uncured solventless synthetic resin. The chamber is evacuated and the transformer heated to remove moisture &c. Sulphur hexafluoride is then admitted until the pressure rises to atmospheric and the gas permeates the parts of the transformer. The chamber is then evacuated again and the moulding vessel filled with resin while the vacuum is maintained. Sulphur hexafluoride is then admitted until the pressure rises to thirty pounds per square inch to assist the penetration of the resin into the interstices of the transformer, and the resin is then cured while said pressure is maintained. any cavities in the resin are filled with sulphur hexafluoride which has a greater dilectric strength than air and is therefore more difficult to ionize. The steps of evacuating the chamber and filling it with sulphur dioxide may be repeated several times. The moulding vessel may form a permanent casing for the transformer.
