ことを特徴としている。[Summary of the Invention] That is, the method for forming a cross-linked rubber/plastic insulated cable connection part of the present invention involves forming an insulating reinforcing layer made of cross-linked rubber/plastic provided on a conductor connection part of a cable connected by stripping. When forming an external semiconductive layer on the outer periphery, an insulating rubber layer that can be fused by heating is applied to the outer periphery of the insulating reinforcing layer.
A plastic tape wound layer is provided, and a semiconductive heat-shrinkable tube based on cross-linked rubber/plastic is attached to the outer periphery of the insulating rubber/plastic tape wound layer and heated to form the semiconductive heat-shrinkable tube. The method is characterized in that the insulating reinforcing layer, the insulating rubber/plastic tape wrapping layer, and the semiconductive heat-shrinkable tube are fused together by shrinking the insulating rubber/plastic tape wrapping layer and melting the insulating rubber/plastic tape wrapping layer.

処理が行われる。 In the figure, in the method of the present invention, first, the cross-linked rubber/plastic insulated cable is connected by stripping the steps,
For example, the cable conductors 2, 2 of the cross-linked polyethylene cables 1, 1 are connected by a conventional method, for example, using a connection sleeve 3, and then an insulating reinforcing layer made of cross-linked polyethylene is wrapped around the outer periphery by a tape-wrapping molding method or an injection molding method. 4 is molded. Thereafter, an external semiconductive layer is formed on the outer periphery of the insulating reinforcing layer 4. At this time, in the method of the present invention, a tape winding layer made of a crosslinkable polyethylene tape containing a crosslinking agent or a non-crosslinked polyethylene tape is formed on the outer periphery of the insulating reinforcing layer 4. 5 is formed, and a semiconductive heat-shrinkable tube 7 serving as an external semiconductive layer is fitted over the cable semiconductive layers 6, 6 on the outer periphery of the insulating reinforcing layer 4 via this tape winding layer 5, and heated. Processing takes place.

レン絶縁ケーブル１の接続部が得られる。 The semiconductive heat-shrinkable tube 7 contracts as it is heated, and then the tape-wound layer 5 melts, and the tape-wound layer 5 is melted by the contraction pressure of the semiconductive heat-shrinkable tube 6.
and the insulation reinforcing layer 4 is a semiconductive heat shrinkable tube 7
completely fused and integrated. At this time, it is desirable to perform the heating under reduced pressure in order to avoid the generation of voids. Since the thus obtained connection part uses a crosslinked semiconductive heat-shrinkable tube 7, the smoothness of the semiconductive layer is not impaired and has good electrical properties. A connection part for a crosslinked polyethylene insulated cable 1 is obtained.

Furthermore, since the thickness of the wound layer of insulating rubber/plastic tape may be small, it does not take much effort to form it, and the work can be completed in a short time.
