For example, the sheath of electrical power cables such as cross-linked polyethylene insulated, polyethylene sheathed cables (hereinafter referred to as CE cables) shrinks toward the cable axis at the intermediate connection due to heat cycles, changes in outside temperature, etc.
A shearing phenomenon occurs, and this misalignment causes the copper tape to break, or water intrusion from the sheath misalignment causes corrosion of the internal components, which is a major cause of cable breakage, accelerates cable deterioration, and shortens the cable's lifespan. Shorten. Because of this, it is necessary to make adjustments and repairs each time to prevent water from seeping in through the sheath misalignment, and power outages may be unavoidable each time.

The ends of the double-chamber cables 8 to be connected are cut in appropriate steps, for example, as shown in FIG. A compression type sleeve 9 is passed between the ends of both the conductors 1 and compressed, and the compression type sleeve 9 is surrounded between the ends of the spacers 13 and wrapped with a sleeve cover 10. An insulating tube 11 is attached over the insulating tube 13, and a semiconductive tape 15 is wound from the outer periphery of the end of the outer conductive layer 4 at both ends to the tapered portion of the insulating tube 11.

Further, the cable shielding copper tape layer 5 is crossed over from the outer periphery of the end of the cable shielding copper tape layer 5, and the crossing P wire 14 is connected to the shielding copper tape layer 5 at the other end.
A waterproof tape 16 is wrapped around the entire outer periphery of the connection part, and a protective tape 17 is further wrapped around the sheath 7 to grip the sheath 7. Since the tape is wound to the outer periphery of the special cable sheath 7 that prevents the sheath from shifting in the axial direction due to the change in the length of the tape, the winding ratio of the tape winding portion has the effect of preventing the cable sheath 7 from shifting slightly. In fact, this preventive force is small, and is in no way capable of maintaining the force necessary to effectively prevent the cable sheath 7 from slipping.

As explained above, even if there is a structure for preventing sheath slippage at the intermediate straight connection part of a conventional CE cable, it cannot effectively prevent slippage, so the present invention reliably prevents this. The structure of the power cable straight connection section is such that there is almost no need to destroy or repair the cable as described above, and the cable north end at both ends of the power cable intermediate connection section has different diameters at both ends. A perforated metal pipe is attached to the steel tape and the cable sheath, soldered to the steel tape, and the cable sheath is heated with a hair dryer, etc., and the surface of the cable sheath is melted and sheathed. Spray the material into the pipe hole,
The stopper is constructed by using a metal braid or a metal wire and passing it over the connection part so as to sufficiently maintain the function of preventing slippage.
