摘要： PURPOSE:To reinforce the connection by charging softened plastic material, which constitutes a reinforcing insulator, into the vacant space made in a high voltage shielded electrode in case of inserting the tip of a CV cable for high voltage transmission into the reinforcing insulator and connecting it so as to constitute a cable connection. CONSTITUTION:The conductor connectors 8 and 8a mounted on the tips of the conductors 2 and 2a of two, pieces of cables are inserted into a conductor joint 10, and the cables are connected inside the high voltage shield electrode 15 of a reinforcing insulator. Plastic material is fused and softened by heating and it is pushed into the space 30 between the ends of the high voltage shield electrode 15 and the conductor terminals from the periphery of the reinforcing insulator by pressing, thus the space is charged with plastic material, whereby the space at the connection is removed and the connection is reinforced. Moreover, by extending the tip of the cable insulator 3 as far as possible to the conductor connector in advance, the space is made small, and the material to be charged can be lessened.

摘要： PURPOSE:To prevent a foreign material from intruding through a changeover valve by eliminating provision of a changeover valve in a filling path for making a reinforcing insulator of a resin material in a cable connecting portion in treating the connecting portion of a cable such as a CV cable used in a high voltage transmission cable line. CONSTITUTION:In a molding portion of a reinforcing insulator for covering the connecting portion of a CV cable, a space 12 in conformity with a shape of the reinforcing insulator is formed inside a metal mold 10, and such a means is used as to press-fill crosslinked polyethylene or the like into the space 12 for solidification. In order to fill the resin material, a resin filling short tube 40 is fixed to the metal mold 10, and resin is supplied to the resin filling short tube from an extruder via a flexible filling tube 30. Resin is filled in the connecting portion between the resin filling short tube 40 and the flexible filling tube 30 by the use of a connecting means such as a box nut 42. After that, the resin filling short tube is crushed so as to form a closed portion, or the resin remaining inside the resin filling short tube is cooled for solidification so as to form a plug made of resin. Consequently, it is possible to maintain a pressure inside the metal mold.

摘要： PURPOSE:To easily detect the existence and position of a pinhole by installing sound wave detecting sensors at two places on a tubular body, detecting the sound which is formed by the leak of the pressurized gas from the pinhole on a pipe, and comparing the wave shape of the sound wave. CONSTITUTION:When a pin-hole 11 exists on a tubular body 1, pressurized gas leaks from inside, and leak noise reaches both the edges of the pipe 1, and detected by the sound wave detection sensors 21 and 22, and the result is displayed on the display devices 31 and 32, and the sound wave shape is compared. If the wave height values of the displayed wave shapes of the sensors 31 and 32 are equal, the pinhole 11 exists at the intermediate point of the positions of the sensors 21 and 22, and if the wave height value on the display device 31 side is sufficiently large, it is judged that the pinhole 11 exists in the vicinity of the sensor 21. The installation division of the sensors 21 and 22 is represented in ratio form from the ratio of the attenuation degree of the wave form, and the position of the pinhole can be calculated.

摘要： PURPOSE:To detect a flaw with good sensitivity when a nondestructive inspection is carried out by transmitting and receiving an ultrasonic signal to and from a polymeric soft material heated to a specified temp. by using an appropriate frequency in follow-up to the temp. of the material. CONSTITUTION:The flaw of a polymeric soft material such as a cross-linked polyethylene (XLPE) is detected at a temp. ranging from ordinary temp. to 90 deg.C. In this case, an ultrasonic probe having an almost flat sensitivity curve B in the frequency band A from 0.9 to 1.7MHz where ultrasonic wave propagation of the XLPE is high is used. Consequently, good detection sensitivity is maintained in a specified temp. range, and the sensitivity to the minute flaw of an even polymeric soft material is improved.
