摘要： PROBLEM TO BE SOLVED: To provide a novel wire jointing method allowing an application even to a part exposed to tension by caulking and jointing a steel sleeve capped to a steel conductor to carry the tension of a wire. SOLUTION: A steel sleeve 4 having a cross section large enough to withstand tension burdened on steel conductors 5 is provided so as to cover the preset length of the steel conductors 5 acting to carry wire tension, and aluminum wires positioned on the outer surface of the sleeve 4 are covered by winding aluminum filaments 2 of the same material as the aluminum wires, or with a cloth type woven material of the aluminum filaments 2 of the same material as the aluminum wires. A sleeve 3 of the same material as the wires is similarly provided to conceal the cover of the aluminum wires. A direct or indirect centripetal explosion shock is then applied to the wires and aluminum filaments 2 via the outer surface of the sleeve 3, thereby compressing and heating the aluminum filaments 2 with the applied shock. Thereafter. the steel sleeve 4 covering the steel conductors 5 are deformed in a centripetal way, with the wires, aluminum filaments 2 and sleeve 3 jointed integrally and metallurgically. The steel sleeve 4 is thereby caulked and fixed to the steel conductors 5. Thus, both a metallurgical joint and a joint capable of withstanding tension are concurrently provided.

摘要： PROBLEM TO BE SOLVED: To reduce an explosion sound, to prevent an explosion gas and scattered objects from inflicting on persons and installations standing in the vicinity, and to execute work safely even in an urban district, on a steel tower, or in an underground disposed passage, when power transmission cables, power distribution cables, or the like are joined together by means of the explosion of an explosive compound. SOLUTION: This is a small sized and light weight device to be used in the event that electric cables 3 are joined together by exploding an explosive compound 1, wherein the explosive compound 1 and a joint part of the electric wires 3 are housed therein a quasi-sealed state and its strength is established according to the kind and quantity of the explosive compound 1 to be used, and a high pressure gas and an explosion sound produced by an explosion are exhausted and propagated, through passages through which the wires 3 are led out from a container to the exterior, as the pressure being reduced and the sound being eliminated, and therefore no danger exists in the proximity, the sound being sufficiently reduced, and explosion-involving work, which was heretofore extremely difficult to be executed in an urban district, on a steel tower for laying electric cables, or in an underground disposed passage, can be executed safely and easily without producing noise pollution.

摘要： PURPOSE: To provide the joining method for joining electric cables not by mechanical compression or squeezing effects but by a metallurgical junction joining not only the parts exposed outside of the stranded cables but also their inner layer parts without giving any damage to the cables. CONSTITUTION: This is the joining method where a protective body 5 made of metal in the same system with the material consisting of the outer layers of stranded cables while being formed into a pipelike curved surface in advance, is covered over the outer circumference of the electric cables 7 to be joined, and a flying plate 3 is disposed at the outer sides of the electric cables, which is made of metal identical to the material of the protective body 5, files in by the explosive pressure of explosives 1 which explode at a speed equal to or more than 70% of the sound speed of the metal so as to be hit against the protective body 5, and the flying plate 3, the protective body 5 and the electric cables 7 are thereby integrally and metallurgically joined. The explosives 1 are set at the outer side of the curved surface of the flying plate 3, let explosion progress from one end of the explosives 1 to the other end progressively, and it is so designed that the moving speed of a point by explosion where the flying plate 3 is hit against the protective body 5, is less than 70% of the sound speed of the metal at the outer layer of the electric cables to be joined, and the flying speed of a flying tube in the direction perpendicuklrly intersected with the progressing direction of explosion, is sufficient enough to join the stranded cable themselves in the inner layer.
