Abstract
The invention discloses an aluminium alloy aerial cable. The aluminium alloy aerial cable consists of the following elements in percentage by weight: 0.1 to 0.5 percent of Co, 0.06 to 0.5 percent of Si, 0.05 to 0.1 percent of Sc, 0.02 to 0.3 percent of Zr and the balance of aluminium and inevitable impurities. By adopting the compositions, the electric conductivity and mechanical properties of the aluminium alloy aerial cable are effectively enhanced, and the aluminium alloy aerial cable is suitable for use as an aerial transmission cable.
Description
Technical field
The present invention relates to a kind of cable, especially relate to the built on stilts cable of a kind of aluminium alloy.
Background technology
In field of power transmission, aluminium light weight, inexpensive, and conductivity is better, specific strength is high, mar proof is good, thereby occupy superiority at electrical field.At overhead transmission line, especially on supertension line and the big span line, the aluminium alloy electric cable is the material of main part of overhead power transmission cable always.In short supply along with the copper resource is the electric wire Development Trend with aluminium for copper, and the aluminium alloy conductor core with multi-functional characteristic is the inevitable requirement of electric wire development.
At present; The 10KV insulated circuit that set up in domestic suburb is the aluminium core; Span can not effectively amplify, and the span of insulated conductor generally can not be greater than 50 meters, and suburb or rural area plain conductor overwhelming majority spans are 65-70 rice now; When former plain conductor transposing was common insulated aluminum wire, more place needed inserted link.The part inserted link is so that span is uneven, and the part not place of inserted link will cause following a series of problem: difficult design, and expense increases; The circuit discrepancy in elevation, sag strengthen, windage yaw is not enough, hidden danger increases; Intensity is impaired, nargin reduces.
The many structural designs of prior art from wire rod, and seldom focus on to go design from the composition of wire rod, for directly using the various aluminium alloy cables of prior art.As aerial cable, its performance does not reach optimization.
Summary of the invention
To the deficiency of prior art, one of the object of the invention is to provide a kind of new aluminium alloy cable, to improve its mechanical performance and transmission performance, is used for built on stilts transmission.
The prepared aluminium alloy cable of the present invention is: a kind of aluminium alloy is maked somebody a mere figurehead cable, and said aluminium alloy comprises that the element of stating weight portion constitutes:
Co 0.1-0.5％
Si 0.06-0.5％
Sc?0.05-0.1％
Zr?0.02-0.3％
Surplus is aluminium and unavoidable impurities.
Also comprise Be 0-0.05%.
Also comprise Mg 0-0.05%.
Also comprise Ti 0-0.02%.
Also comprise V 0-0.03%.
