摘要： PURPOSE:To shorten the time of work and reduce a cost, by providing the high stress section of a cable bed rise section with a conductive bridged heat- shrinking tube. CONSTITUTION:On a cable insulating unit 1b, a polyethylene tape including a bridging agent is heat-molded, and a polyethylene tape layer 4 including the bridging agent, and the bridging polyethylene tape layer 5 of the bridging polyethylene tape and electrode foil 5a inserted into a space between a cable- internal conductive layer 1c and a terminal 11, are formed. A rise section 4a to a top plane section is wound up with a conductive polyethylene tape 8 to form a capacitor cone. The end surface of the rise section 4a is covered with a conductive bridged heat-shrinking tube 6 inserted previously on the periphery to a cable-external conductive layer 1a, to be moved and connected to, via a pre-mold-connected unit 7 with a semi-bridged conductive layer 7b formed on a semi-bridged insulating layer 7a, and the tube 6 is heatshrunk to form a rise section conductive-layer.

摘要： PURPOSE:To prevent dust from being adsorbed in a manufacturing process and to improve the quality of products by a method wherein processd between extruding and winding rubber or plastic material is carried out in an atmosphere of ionization. CONSTITUTION:Tape material 2 is heated, fluidized and extruded by an extruder (a), moved from a slit 3 of an extruding die onto a rotary table 4 and rolled by rollers 5 down to a desired thickness before the tape material 2 is cooled. The tape material is cut to a desired with to obtain a tape 6 and it is wound about a winding up reel 7. All these processes are carried out in an atmosphere of ionized air 9. In other words, the whole manufacturing device of rubber or plastic is covered with a case 8 and pure ionized air 9 is allowed to flow from an ionized air generator 10 equipped at one corner of the manufacturing device. Accordingly, the tape 6 is not charge, dust or the like is prevented from being adsorbed.

摘要： PURPOSE: To obtain a high-gel content PE tape, sheet or block by efficient gelation, by heating and crosslinking an uncrosslinked PE material containing a crosslinking agent in an inert gas atmosphere at a specified pressure.
CONSTITUTION: For example, an uncrosslinked PE material containing a crosslink- ing agent, e.g., dicumyl peroxide, is processed into a sheet by extrusion at a temperature in the range in which the crosslinking reaction does not occur. This sheet material is wound around a core such as a metal pipe, together with a separator such as polyester. Wound around the outermost layer is a polyester tape or the like, and the roll is heated and crosslinked at 150W250°C for 30minW5hr in an inert gas (N
2 ) atmosphere at a pressure of 0W10kg/cm
2 . Then, the tape is cut to a predetermined width and length to obtain a crosslinked tape.
EFFECT: Gel fraction of at least 80% can be attained.
