Claims (1)

[Scope of Claim for Utility Model Registration] 1. In an overhead ground wire of anti-snow accretion type made by twisting aluminum-coated steel wires in the outermost layer and forming fin-like protrusions on a part of the twisted strands, the above-mentioned fin-like protrusions A snow-resistant overhead ground wire made of aluminum alloy wire. 2. The anti-snow accretion type overhead ground wire according to claim 1, which is a utility model registered claim, wherein the aluminum alloy wire forming the fin-like protrusions has a steel core with a smaller wire diameter than other wires inside. 3 Utility model registration claim 1 or 2 where the overhead ground wire is an optical fiber composite overhead ground wire in which strands are twisted around the outer periphery of an OP unit containing an optical fiber.
Overhead ground wire with difficulty in accreting snow as described in section. 4. A non-snow-accreting type overhead ground wire according to any one of claims 1 to 3 of the utility model registration claim, in which the twisted strands are compressed into a fan-shaped cross section. 5. The anti-snow-accreting type overhead ground wire according to any one of claims 1 to 4 of the utility model registration claim, wherein all of the twisted strands are twisted by a twisting method with return twisting.
