The present invention relates to a surface modified overhead conductor with a coating that allows the conductor to operate at lower temperatures. The coating is an inorganic, non-white coating having durable heat and wet aging characteristics. The coating preferably contains a heat radiating agent with desirable properties, and an appropriate binder / suspension agent. In a preferred embodiment, the coating has L* value of less than 80, a heat emissivity of greater than or equal to 0.5, and / or a solar absorptivity coefficient of greater than 0.3.

Aluminum cable type electrical conductor having at least one stranded conductor based on conductive wires with an aluminum core coated with an intermediate layer of copper itself coated by a surface layer of nickel. The surface layer of nickel has a thickness from about 1.3 μm to about 3 μm, it has sufficient continuity to resist a polysulfide bath continuity test for at least 30 seconds without visible traces of attack of the copper appearing at ×1O magnification. This kind of conductor is particularly suitable in small diameters for conducting electricity in aircraft and motor vehicles.

A transmission line assembly for transmission and distribution of high voltage power which comprises a conductor, a separate messenger member and coupling means. The conductor has a predetermined length. The separate messenger member has a predetermined length. The coupling means couples the messenger to the conductor to the messenger. The messenger member and the conductor remain structurally separate from each other and functionally independent.

A protective conductor cover for a distribution line conductor includes an elongate cover body having a longitudinal axis and including first and second opposed, elongate sidewalls. The sidewalls define an axially extending cover channel terminating at axially opposed end openings, and an axially extending bottom opening communicating with the cover channel and terminating at the axially opposed end openings. The protective conductor cover further includes an integral conductor retention tab having a base end attached to the first sidewall and extending laterally from the first sidewall into the cover channel to a free terminal end of the conductor retention tab. The conductor retention tab is configured to elastically deflect and secure the conductor in the cover channel when the conductor is inserted into the cover channel through the bottom opening.

The invention relates to a tower for a wind turbine and to a cable guide for a tower of a wind turbine, wherein a machine housing for the wind turbine is arranged on the tower such that it can rotate by means of the azimuth bearing about a vertical axis which runs in the longitudinal direction of the tower. Current-carrying cables, such as power cables, are routed in the tower of the wind turbine out of the machine housing from electrical components to the ground. These comprise a multiplicity of cables, for example a plurality of cables for electrically carrying individual phases of alternating current, in particular three-phase alternating current, cables for ground conductors and / or signal and control cables. One object of the invention is to specify improved routing of the cables which, inter alia, avoids the disadvantages of the prior art.One particular aim is to ensure that the current load capacity of the cables is ensured, and / or that wear between the cables is reduced. According to the invention, the object is achieved by the features of the main claim 1, by the tower having at least two looming apparatuses, which are suitable for joining the individual cables which run longitudinally in the tower together to form a cable loom with the cables fixed with respect to one another. The looming apparatuses are attached to the cables between an upper and a lower area of the cable loom. In this case, geometric configuration of the looming apparatus ensures that a specific minimum separation at least between three cables is not undershot.

The invention discloses an anti-icing cable. The cable comprises a core, a shielding layer and an anti-icing layer arranged in sequence from inside to outside, wherein the anti-icing layer comprises the following raw materials by weight: 60-75 parts of fluorosilicon resin, 20-30 parts of methyl vinyl silicone rubber, 10-15 parts of SiO2-glass fiber gel, 5-8 parts of polypropylene fiber powder, 3-5 parts of nano SiO2, 4-6 parts of nano TiO2, 0.5-1 part of a dispersing agent, 0.5-1.5 parts of a flame retardant, 1-2 parts of a silane coupling agent and 1-2 parts of an antioxidant. The anti-icing cable has excellent hydrophobic property and anti-icing performance, and is excellent in insulating performance, high in compressive strength, high in flexibility and anti-aging; and the anti-icing layer of the anti-icing cable can replace the insulating layer in the cable and a sheath outside the cable, so that the cable mass is lowered and the service life of the cable is prolonged.

An electrical transmission line repair device including a first conductor clamp, a second conductor clamp and at least one tie rail extending between the first and second conductor clamps in a spaced apart orientation. The first conductor clamp including a lower assembly and an upper assembly. The lower assembly and the upper assembly are slidably engageable with each other so as to define a conductor cavity extending therealong. Clamping fasteners are configured to extend through openings in the upper assembly so as to be threadable toward and away from the conductor contact region of the lower assembly within the conductor cavity.
