NOVELTY - This utility model claims a kind of a graphene nano-material of lead, belonging to the overhead transmission line lead to the technical field of aluminium-copper and so on traditional metal material conductivity improves, so as to deliver an overhead power transmission line capacity is limited. A guide line is a, the first lead comprises an inner layer and an outer layer, an inner layer composed of the steel wire or carbon fibre, nanometre material graphene nano-tube wire or composite wire twisted, the twisted outer layer composed of graphene nanometre sheet material, so as to form two lead the graphene material is composed of a round wire of a tube wire or composite twisted wire, the wire are clung to each other, to form a structure, wherein the circular section of the composite wire is carbon fibre composite material, the circular cross-section is a graphene nano material. This utility model of the graphene nano-material as guide line can effectively reduces the line loss and improve the transmission power of an overhead power transmission line, allowing carrying capacity of the graphite guide line is a common wire 10.
