It is often required to house electrical apparatus in pressure vessels capable of withstanding considerable pressure, either external or internal, and to make connection with such apparatus. For this purpose, electrical cables containing one or more insulated conductors must be passed through the walls of the vessel. This paper deals with glands forming the entry of such cables into the vessel. It states the fundamental requirements of cable entry glands and gives a summary of the principles of construction employed. Experimental work is described which led to the development of two designs of gland. The first of these was developed specifically for the entry of submarine telecommunication cables into submerged repeaters containing electronic amplifying equipment, in particular the submerged repeaters used on the British section of the first transatlantic telephone cable system. Both manufacture and testing of these glands are reviewed. The second design dealt with is a simplification of the first, based on the experience gained. Some special operating conditions encountered are mentioned and the means of meeting the resulting additional requirements are discussed.
