Abstract
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.
