摘要： PROBLEM TO BE SOLVED: To obtain a power cable joint, which can suppress scattering of broken pieces to a minimum, when an insulating cylinder breaks due to the rise of the inner pressure of a joint. SOLUTION: A reinforcing cylinder 6, consisting of two cylinder elements 7 and 7' is buried in an insulating cylinder 4 which is incorporated in order to electrically isolate cable protective metal fittings 2 and adaptor metal fittings 3 from each other. Cut parts 10 are formed at prescribed positions in the circumferential directions of the cylinders 7 and 7'. When the inner pressure of the joint is elevated by insulation breakdown, the cut parts are first broken for reducing the internal pressure. With this constitution, the break of the whole insulating cylinder 4 can be avoided, and scattering of the broken pieces can be suppressed to a minimum.

摘要： PURPOSE:To improve the efficiency of the connection work by enabling extension of a compression sleeve at the free end thereof during connection of the power cable conductor. CONSTITUTION:Cable conductors 4, 4' of power cable to be connected are inserted respectively at the base end side of the right and left compression sleeves 8, 9 having the threading portions 11, 12 at the external circumstances thereof for the compressed connection and these end portions are arranged to face with each other keeping therebetween a very short distance. Next, a connecting sleeve 13 having previously been threaded with the threading portion 12 on the one compressed sleeve 9 is then threaded to the other compressed sleeve 8 to couple the cable conductors 4, 4', a valley portion generated by movement of the connection sleeve is covered with a half-split collor 15 and the sleeve 14 for covering the valley portion which has been inserted at the external circumference thereof is moved for connection through compressed fixing. Moreover, for the connection of conductor of the single core OF cable, a reinforcing steel pipe for obtaining oil path is previously inserted into the center area of the right and left compressed sleeves.

摘要： PROBLEM TO BE SOLVED: To provide a jointing part of a CV cable (cross-linked polyethylene insulated power cable) which is made to be compact by reducing a working length and can be made by a simplified working procedure. SOLUTION: Conductors 2a and 2a' of 1st and 2nd CV cables 2 and 2' and a high-voltage shielding electrode 111 are connected with a conductor connection part 12. Metallic shields 2d and 2d' of the 1st and the 2nd CV cables 2 and 2' are connected by insulated connection through an edge cut part 110b, integrally formed with an epoxy insulator 110. Since the edge cut part 110b is integrally formed with the epoxy insulator 110, and moreover, the transfer of an epoxy unit 11 is not necessary, the size of the joint part on a longitudinal direction can be reduced and a working procedure can be simplified.

摘要： PROBLEM TO BE SOLVED: To attain holding with a stress relief cone holder from the time of fitting a stress relief cone, and prevent the stress relief cone from sliding off by dividing the stress relief cone holder into two upper and lower pieces to be constituted of a lower holder and an upper holder which are respectively capable of being fitted independently. SOLUTION: A stress relief cone holder H is constituted of a lower holder H1 and an upper holder H2. The lower holder H1 is fitted after a hand wound stress relief cone 6 is completed. After a strip part 1 at the lower end part of the lower holder H1 is fastened at the outer periphery of the end part of a cable metal sheath 11 by a band, an axial strip part 2 is fitted at the slope of the hand wound stress relief cone 6 along its broadening part of the cone at the outer periphery of a metal wire 12 for blocking. After a factory- manufactured capacitor cone 7 is inserted in the upper part of the hand wound stress relief cone 6, the upper holder H2 is fitted at the outer periphery of the metal wire 12 for blocking.

摘要： PURPOSE:To provide a termination for an oil-filled power cable in which the lead wire for temperature measurement can be inserted into the oil channel of a conductor through a conductor pull-out rod. CONSTITUTION:A conductor pull-out rod 1' to be fitted over the conductor terminal of an oil-filled power cable within a bushing is provided with a hole 4 extending axially from a lead-out end, and a small chamber 6 located on the joint side. The hole 4 is opened at the upper face of the small chamber 6 such that a closable valve 10 can move freely within the small chamber. A pull string 11 connected with the valve 10 is pulled to the outside of the rod 1' to incline the upper face 3a' at an end of the conductor having an oil channel in the cable forming the bottom of the small chamber 6 at a predetermined angle with respect to a horizontal plane thus shifting the dropping valve 10 to one side of the opening of the oil channel.
