摘要： An optical cable for use in an overhead optical transmission system in which the cable is supported along the route of the system by means of towers, masts or other upstanding supports that are also employed to support electrical power cables, comprises one or more optical fibres and an electrically insulating jacket (8). The cable includes an array of elongate conductive elements (10, 12) each of which extends along a portion of the cable, adjacent conductive elements axially overlapping each other with overlapping portions circumferentially spaced apart to form a composite conductive path that extends along the cable and is interrupted when the cable is dry. Adjacent conductive elements (10, 12) are resistively coupled to each other when the surface of the cable is wet to form a continuous electrically conductive path along the cable. Such a form of cable has the advantage that the possibility of dry-band arcing under wet conditions is reduced by disrupting the geometry that allows such bands to form.

摘要： A linear element (1, 61) suitable for extending between, and being supported by, towers of an overhead electrical power transmission system, includes one or more electrically semiconductive components (54, 62) that cause the element to have a linear resistance of 0.05 to 100 Mohms m , and which exhibit a negative temperature coefficient of resistance. The element may be a rope used for stringing up conductors of the system or it may be an optical cable. Preferred materials for forming the semiconductive components include carbonaceous fibre tows formed from pyrolised acrylonitrile fibres. The element has a controllable and reproducible resistance for reducing or eliminating dry-band arcing.

摘要： A method of installing an optical cable in an overhead power transmission line which comprises supporting an optical cable (1), which has an overall protective sheath of electrically insulating material, in long lengths between towers employed to support at least one electric power transmission line (2) which is on load and, after the optical cable (1) has been so installed and while the overhead electric power transmission line is on load, providing on or in the supported optical cable at least one longitudinally continuous path (11) which extends throughout substantially the whole length of the supported optical cable and which is sufficiently electrically conductive to carry along the cable (1) any currents that may be capacitively induced. The method enables a cable that will not be subject to dry-band arcing to be installed without danger to personnel during installation.

摘要： A method of forming a joint in an optical line that extends along a phase conductor (1) of a high voltage overhead power transmission system, comprises: (i) forming a length of optical cable (10) which comprises a plurality of optical fibres; (ii) encapsulating the optical fibres; (iii) providing an intermediate region of the length of optical cable with an outer, non-tracking jacket (12) so that a part of the length of optical cable extends from each end of the outer, non-tracking jacket; (iv) installing the jacket so that it extends between phase potential and any other potential to which the cable will be subjected; and (v) connecting one end of the optical fibres of the optical cable to fibres in the optical line of the phase conductor (1), and connecting the other end of the optical fibres of the optical cable to another optical line. The parts of the length of the optical cable that extend from each end of the outer, non-tracking jacket (12) have a sufficient length that connections can be formed between the optical fibres and the optical lines at points remote from regions in which the cable extends along high electrical field gradients. This has the advantage that the optical fibres of the assembly which, in use, will extend between the potential of the phase conductor and earth can be encapsulated in the factory under controlled conditions, and conventional means may be employed to connect the cable.
摘要翻译：一种在沿着高压架空输电系统的相导体（1）延伸的光线路中形成接头的方法，包括：（i）形成包括多根光纤的一段光缆（10）; （ii）封装光纤; （iii）将光缆的长度的中间区域设置有外部非跟踪护套（12），使得光缆长度的一部分从外部非跟踪护套的每个端部延伸; （iv）安装护套，使其在相电位和电缆将要经受的任何其它电位之间延伸; 以及（v）将光缆的光纤的一端连接到相导体（1）的光线路中的光纤，并将光缆的光纤的另一端连接到另一条光线路。从外部非跟踪护套（12）的每个端部延伸的光缆长度的部分具有足够的长度，从而可以在远离其中的光纤线路和光线路之间的点处形成连接，电缆沿高电场梯度延伸。这样做的优点在于，使用中将在相导体和地电位之间延伸的组件的光纤可以在受控条件下在工厂中被封装，并且可采用常规的方法来连接电缆。

摘要： An optical fibre strain gauge (1) for an engineering structure e.g. a bridge, building, pipe, plant or the like, comprises: (a) a plurality of supports (8, 10) for the optical fibre that can be located on a surface of the structure and are spaced apart from one another over a part of the surface; and (b) at least one optical fibre (12) that is looped around the supports so that it extends between the supports, the optical fibre being fixed to the supports so that the length of the part of the fibre extending between the supports will vary in accordance with strain of the surface of the structure. The optical fibre(s) (12) can be looped around the supports (8, 10) a number of times, which enables the fibre(s) to be held more easily, and enables the strain gauge to incorporate a length of fibre significantly greater than the dimension of the area of the structure that is being monitored. The fibre(s) will normally contain reflectors such as Bragg gratings to enable signals to be monitored.

摘要： A construction machine (such as a piling rig) is correctly positioned on a work site by (a) providing the machine with a mast (5) having a nominally vertical axis passing through the centre of operation of the machine at ground level; (b) providing a satellite navigation system receiver (preferably a high-precision GPS P-code receiver) and locating its antenna (11) on the said axis at the top of the mast; (c) providing means (12) for determining the displacement of the mast from its nominal vertical position; (d) obtaining output readings from the said navigation system receiver when the displacement is less than a predetermined limit (which may be reduced as the target position is approached); and (e) positioning the machine manually or automatically in response to those output readings. If output readings are obtained when the displacement is outside the chosen limit, they are distinguished from usable positioning readings, for example by dimming or changing the colour of the display.

摘要： Filled polymer compositions, especially low-smoke-and-fume cable insulation compounds, are subjected to reduction in cross-section by shear flow in the solid state (plastic flow) in order to improve dispersion of the filler. The reduction ratio is at least 10:1 and the shear flow is maintained for at least 0.3 sec. Preferably the softening point is not exceeded, but if it is the exposure time is limited to one minute; no substantial excursion above the decomposition temperature of any ingredient is allowed. ''Conform'' extrusion is the preferred way of achieving the required flow.

摘要： An electrode for electrochemical processes comprising an electrically conductive wire having a coating of a polymer having dispersed in it Magneli phase oxide particles, at least half the mass thereof being constituted by particles with diameters in the range 200 to 1000 mu m. This results in a very substantial increase in conductance compared with the conventional use of particles in the approximate range 1-50 mu m. To avoid breakdown of the rather fragile particles, the energy absorbed in mixing the oxide with the polymer should be restricted to at most 200J/g.
