An electric power cable is provided, wherein the electric power cable comprises an organic silicon insulating coating layer capable of being cured at room temperature. Generally, the electric power cable comprises a cable conductor capable of transmitting electric energy, and the organic silicon insulating coating layer is coated to the exterior surface of the cable conductor. The cable conductor may be an exposed overhead bare conductive wire, and the organic silicon insulating coating layer is especially suitable for being formed on the exterior surface of the overhead bare conductive wire by coating directly thereto.

A coating composition includes a fluoroethylene vinyl ether copolymer, a cross-linking agent, and water. The coating composition reduces the operating temperature of an overhead conductor by at least about 5° C. or more compared to a similar uncoated overhead conductor when the operating temperatures of each overhead conductor are measured at about 100° C. or higher and the coating composition is substantially free of solvent. Methods for making a coating composition and for making a coated overhead conductor are disclosed.

A stranded conductor (2) including a specific number of a first type of wire (5) which, in cross-section of the stranded conductor, are arranged in a hexagonal pattern around a central wire in at least two layers. The wires arranged at the vertices of the hexagonal pattern are of a second type of wire having in principle a smaller diameter than the first type of wires. The interstitial spaces (10) between the first and the second wires are filled by a sealing agent (3).
