Provided is an on-line ice-melting apparatus. The apparatus is configured for melting the ice on a three-phase line. The apparatus includes an adjustable reactor, a grounding transformer, a controller, and an auxiliary circuit. The grounding transformer, the adjustable reactor, the auxiliary circuit, and a line of any phase of the three-phase line form a first control loop. The adjustable reactor includes a working winding, a control winding, and a short-circuit winding. The working winding is connected between the grounding transformer and the auxiliary circuit. The controller is electrically connected to the control winding and the short-circuit winding separately.

The present invention relates to a powerline de-icing device primarily comprised of a body, further comprised of at least one solar panel, at least one battery, at least one heating element, and at least one heat-able wire. In the preferred embodiment, the device is comprised of a solar panel that supplies power to the battery, wherein the battery supplies power to the heating element which provides an electrical charge to the wire and in turn heats the wire. The wire can then be wrapped and secured around a power line to prevent ice and snow from forming on the power line. Furthermore, the device may be comprised of a temperature sensor that automatically activates the heating element when the ambient temperature around the device is below a threshold temperature (e.g., 32 degrees Fahrenheit).

Disclosed is a device for monitoring icing of a transmission line and preventing a tower from falling down, including a power transmission tower, an insulator string and a connecting mechanism; the connecting mechanism includes two connecting plates, and a monitoring-control connector and a damping component are arranged between the two connecting plates; sides of the two connecting plates are respectively provided with connecting grooves matched with two ends of the monitoring-control connector; the monitoring-control connector is provided with a monitoring component in signal connection with a master station; the two ends of the monitoring-control connector are respectively provided with load release components and are fixedly connected with the two connecting plates, and sides of the two connecting plates further from the monitoring-control component are fixedly connected with the power transmission tower and one end of the insulator string respectively, the other end of the insulator string is hung with wires.

Provided is a wire rope with resin wire, including a wire rope body in which a plurality of strands are twisted together, and at least one resin wire spirally wound around the wire rope body along a recess between the strands. Strand grooves into which the strands can fit and a resin wire groove into which the resin wire can fit are formed spirally along the twist of the wire rope with resin wire, in a winding hole of a resin wire winding die used for winding the resin wire around the wire rope body. As a result, the resin wire can be easily and reliably mounted on the wire rope body and a wire rope with resin wire can be thus produced.

The present invention is related to a method for detecting and/or measuring atmospheric accretion on a suspended electrical cable span (2) of overhead power lines, said suspended electrical cable span (2) having a sag (D) and a local tension (H), and being submitted to wind pressure (w.sub.wind), comprising the steps of independently: measuring said sag (D), and optionally measuring the wind pressure (w.sub.wind), over a first time range, measuring the local tension (H) over a second time range,
the results of both steps being complemented and/or combined, so that to allow atmospheric accretion detection and/or measurement.

Methods and systems for an ice cap to prevent ice buildup on electrical cables or wires such as grooved cables that carry electricity to transportation vehicles are disclosed. The ice caps can be attached to grooved cables or wires and partially envelop them. The ice cap includes an inverted V-shaped structure and a pair of members descending from its apex and configured to form a canopy over the cable while allowing free access to the bottom portion of the cable by a current collector. It provides a cover over the cable allowing run off of rain, snow and sleet. Grooves present on the edges of the descending members disrupt ice buildup on the cable and increase the ice prevention efficiency of the ice cap. Descending members of the ice caps could also extend over neighboring cables to which they do not attach directly to prevent ice formation on them.
