Abstract:
Methods and apparatus for forming devices including dead-ends and insulator ties from flat and other strips of material, as well as the devices themselves, are disclosed. Components of these devices may be formed continuously from a single strip, avoiding the need to weld or clamp the components together. Forming the devices in this manner reduces the possibility of stresses or non-uniformities forming when the components are joined and permits continuous automatic or semi-automatic manufacture to occur.
Abstract:
The invention concerns a method of fitting an optical-fibre cable (1) on the cable (2) of a power transmission line using at least one adhesive tape (5, 6) wound on in a helical manner.
Abstract:
A cable retaining apparatus is disclosed. The apparatus includes a band that is wrapped around a group of cables and a clamping portion that holds the ends of the band. The clamping portion has a body portion that is fixed to one end of the band. The body portion also has an axle mounted to it, the axle having a slot cut into it to receive the other end of the band. The end of the axel has a rotatable head for engagement by a tool such as a spanner so that rotation of the head causes the axel to rotate. The body portion also has an aperture that is aligned with an aperture in the axel so that a pin can extend through the apertures to prevent rotation of the axel. In use the band is placed round the cables and its end inserted into the slot. The axel is then rotated and band winds around the axle until it tightens around the cable. The pin is then inserted into the apertures to prevent the band unwinding.
Abstract:
A cable lasher (2) is provided for securing a utility cable, such as a telephone or transmission cable (5), to a support strand (3) strung in the air between adjacent utility poles. The lasher is pulled forwardly along the support strand and releases lashing wire (7) from a drum at the rear of the lasher. The lasher has a pair of drive wheels that rotate on the support strand. The drive wheels translate linear motion of the lasher into rotational motion of the drum as the lasher moves forwardly. Lashing wire is released from the rotating drum and helically wrapped around the cable and the strand. Tension in the lashed wire is maintained by an adjustable latch assembly which prevents the lasher from moving rearwardly to unwind the wire.
Abstract:
The invention relates to a method for continuously attaching spiral-shaped fastening elements (WBE) for a cable (K), which is to be fastened to a bearer or high voltage cable (S). According to the inventive method and device, a spring band (FB) is shaped in the form of a spiral and a scraper (A) places said spring band upon a spiral shaped sleeve (WH) situated on the combined bearer or high voltage cable (S)/cable (K) to be bound.
Abstract:
It is disclosed a figure of eight cable comprising a first cable element comprising a first core enclosed by a first outer sheath, a second cable element comprising a second core enclosed by a second outer sheath and a web joining the first and second outer sheaths so as to provide the cable with a major plane of symmetry X which comprises the longitudinal axes of the first and second cable elements. The cable also comprises at least one strength member embedded within the first or second outer sheath. All the strength members of the cable are substantially located on the major plane of symmetry X of the cable.
Abstract:
Dier Erfindung betrifft ein Laschband zur Befestigung eines optischen Kabels an einer elektrischen Freileitung. Das erfindungsgemässe Laschband verfügt über einen Zugkräfte aufnehmenden Trägerkörper (11, 21) und einen den Trägerkörper vollständig umhüllenden Mantel (12, 22). Erfindungsgemäss umfasst das Laschband weiterhin mindestens einen Lichtwellenleiter (14, 24). Das erfindungsgemäße Laschband dient nicht nur der Befestigung des optischen Kabels an der elektrischen Freileitung, vielmehr kann das Laschband nun auch zur Datenübertragung genutzt werden.
