Abstract

The utility model belongs to an ultra-high-strength energy-saving compatibilization conduction wire, which is characterized in that a stranded low-resistivity conduction body is arranged outside an ultra-high-strength steel core of a composite plating layer. The low-resistivity conduction body can increase the current carrying capacity of the conduction wire on the premise of low line loss, thereby reducing sags in operation. The section of the conduction wire is smaller than that of a traditional conduction wire, and the windage can be reduced. The minimum tensile strength of each steel wire of the ultra-high-strength steel core is at least 2000Mpa, and each steel wire has double anticorrosion functions (namely, chemical erosion resistance and electrochemical corrosion resistance), and the characteristics such as low creeps, low heat expansion coefficients and fatigue resistance. The ultra-high-strength energy-saving compatibilization conduction wire reduces the cost of products, saves the electric energy transmission cost, improves the using performance and especially prolongs the service life of the conduction wire; in the newly-built power transmission line, the conduction wire can replace the traditional steel-cored aluminum strands and round wire concentric lay overhead electrical stranded conduction wires; and during the compatibilization modification of the power transmission line, the conduction wire can replace not only expensive and great-loss heat-resistant zirconium-aluminium alloy conduction wires with heat-resistant steel cores (invar), but also clearance-type compatibilization conduction wires and carbon fiber-cored compatibilization conduction wires which are difficult to construct.

Description

Superhigh intensity energy-saving capacity-increasing lead
Technical field
The utility model belongs to a kind of lead, definite a kind of superhigh intensity energy-saving capacity-increasing lead of saying so.
Background technology
Present common low arc drop capacity-improving conducting wires, as the heat-resisting zirconium alloy lead of heat-resisting steel core (invar), gap lead, carbon fiber core lead etc., though increased the ampacity of lead, there are drawbacks such as line loss is big, cost is high, construction complexity in the sag in the time of also can reducing hot operation.Though and soft aluminum conductor has some improvement, as Chinese patent 200710190123.6, because of its steel core minimum tensile strength has only 1770Mpa, the transmission line of inapplicable big leap, and steel core coating kind is independent, corrosion proof function is single, is not suitable for complicated corrosive environment, and the range of application of lead is restricted.
Summary of the invention
The purpose of this utility model is to provide a kind of superhigh intensity energy-saving capacity-increasing lead.It is characterized in that increasing the ampacity of lead under the prerequisite of low windage and low line loss, thereby reduce the sag when moving.Superhigh intensity steel core individual wire minimum tensile strength is not less than 2000Mpa, and the dual preservative efficacy of anti-chemical corrosion and couple corrosion and low creep, low thermal coefficient of expansion and and the characteristic of antifatigue are arranged.
The purpose of this utility model is realized by following method:
There is stranded low resistivity conductor in the outside at the superhigh intensity steel core that composite deposite is arranged.Low resistivity conductor can be considered and gently is overlying on the superhigh intensity steel core.Low resistivity conductor reduces the line loss of current delivery.When low resistivity conductor is fan-shaped or trapezoidal, increase the conductor cross-section utilance, can reduce under the situation of conductor cross-section, increase current delivery, to reduce the lead windage.The high-tensile of superhigh intensity steel core plays a part to support low resistivity conductor, has only the superhigh intensity steel core when setting up as carrier.The individual wire minimum tensile strength is not less than 2000Mpa.The composite deposite of superhigh intensity steel core surface has the dual preservative efficacy of anti-chemical corrosion and couple corrosion.The superhigh intensity steel core is by the special process manufacturing, and low creep, low thermal coefficient of expansion and and the characteristic of antifatigue are arranged.
Owing to adopted such scheme, make the utility model in use, under the prerequisite of low windage and low line loss, improve the ampacity of lead, sag when reducing operation, and the dual preservative efficacy of anti-chemical corrosion and couple corrosion and the characteristic of low creep, low thermal coefficient of expansion and antifatigue are arranged.To save the power delivery cost, improve the lead serviceability, extension lead useful life.
Below in conjunction with accompanying drawing the utility model is elaborated:
