Limiting dry band arcing on an all-dielectric self-supporting cable; arc gap devices

To limit dry band arcing adjacent an earthed suspension region 20 of an all-dielectric self-supporting (ADSS) cable 10 suspended at the region 20 from a tower which also supports power transmission lines, a current path incorporating an arc gap, or equivalent solid state device such as a varistor, is provided between electrically conductive clamps 28, 26 disposed around the cable 10 at the earthed suspension region 20 and at a location 22 remote from region 20, respectively. An arc gap may be defined between a tubular sleeve 32 connected to and adjacent the clamp 26 (or 28) and a rod 30 connected to clamp 28 (or 26) and extending through the sleeve 32. Insulating arms 34 position the rod 30 on the axis of the sleeve 32 to define an arc gap therebetween. Such an arc gap device defined by a sleeve 32, rod 30 and insulators 34 may also be used instead of arcing horns in covered conductors, transformers or any other application which traditionally uses arcing horns.

Straight-Through Power Lines

Send Electricity Over Power Lines without Capacitors to Reduce Resistance and power outages, and increase efficiency. 1) Builds on Patents for Power Lines; and2) My current patent (submitted with this one) for Air in Vacuum Tubes as Superconductor. Power lines should be constructed with few or no capacitors.Lightening striking capacitors cause power outages, and capacitors actually create resistance along the line that reduces efficiency. Channeling electricity through power stations and substations and then in homes, offices, and businesses—in which capacitors would be reduced or eliminated along the way—would be much more efficient, as well as reducing power outages from over-loaded circuits. My other patent application idea for air in vacuum tubes as a superconductor could also be used with this idea on power lines. Air, with particles reduced as much as possible, would conduct electricity better than any metals or other substances.

Electric supply cable for outdoor appliances - is supported from helium filled balloon to avoid entanglement

The application is principally to outdoor electrical appliances in a domestic setting, for example lawn mowers or rotary cultivators (4). For appliances connected to mains supply the trailing cable can cause difficulties and accidents. It is therefore proposed to support the cable (2) clear of the ground by hanging it from a ballroom (5). The main connection is typically taken from a suitably placed outdoor socket outlet (1) and supported by the balloon (5) in a sliding clip or ring. As the appliance s moved so the pull on the cable varies the balloon height. A typical maximum altitude is 8 meters.

Marker ball for high voltage cables

In a method of installing a marker ball on high-voltage overhead cables, the cable is first fitted with a crosswise intermediate bearing (8) which is then fitted with a marker ball in the form of two half-balls (1, 2) which are secured to the ends of the bearing (8). The two ball halves (1, 2) have rims (3, 4) which engage each other. As the mounting is carried out by using an intermediate bearing crosswise to the cable, the installer has a better access to the attachment points (10), neither one of which is located on the opposite side of the ball from the installer.

Insulated electrical equipment

An annular guard (20) for mounting on a high voltage insulator extends laterally thereof for a sufficient distance so as to prevent small wildlife such as squirrels from forming a short circuit between the opposing ends of the insulator at high voltage and earth potential respectively. The guard (20) is formed in two planar parts (24, 26) that are pivoted together (28) so that they can be relatively rotated between an open condition for mounting onto a live insulator and a closed condition for being secured thereto. Overlapping regions of the two parts are secured together (30, 32, 34, 36, 38) in the closed condition.

High voltage cable and insulator shield

A plastic shield for a cable and insulator is described having a center section for covering the insulator. The center section has an opening at both its ends for the cable. Proximate each opening is a pivotable flange, where the flange pivots at one end of the flange. An arm extends from each of the cable openings of the center section, and each arm covers the cable exiting the center section. Each arm is pivotally attached to the other end of the associated flange. The length of the flange will typically be about 2-3 inches. The flange allows its associated arm to be moved over a wide range of lateral angles (e.g., up to 45 degrees) and allows the arms to have a lateral offset relative to the center line of the center section and insulator to accommodate a cable that is offset from the center line.

Apparatus for exciting luminous tubes

Protection device: surge suppressing conductor

A lightning protection or internal surge device designed to suppress surges on electrical transmission or distribution lines by expending some of the excess energy in the form of corona discharge in both wet and dry conditions. The device is a very thin (of diameter not exceeding 0.1mm) conducting wire, fiber, filament, or a bundle of such filaments, or a yam or woven or knitted fabric made of such fibers or wires which is wound around a live conductor or ground wire forming a coil. When the coil is exposed to the fields created by the voltage surges on the line or ground wire it enhances corona losses on the line thereby damping/suppressing the surges as well as prolonging the front time of the surge to reduce its steepness.
