Description
Technical field
The present invention relates to a kind of aluminium alloy rod, particularly relate to the manufacturing process of a kind of aluminium alloy rod.
Background technology
With growing continuously and fast of Chinese national economy, the demand of electric power is also sharply increased.Power transmission sequence require to
Big electric current, super-pressure direction are developed, and this requires to increase the transmission line capability of wire.As power transmission electric network construction is constantly added by China
By force, the continuous extension of Three Gorges power transmission engineering circuit, transferring electricity from the west to the east, north and south confession mutually, on national network, and to having run decades
The transformation of old circuit, country is badly in need of building one can meet industrial and agricultural development demand, the most reliably, safest, save
Type electrical network.In capacity-increasing transformation engineering, if rebuilding the land acquisition to be carried out of whole piece circuit, passage felling, so can cause expense
Investing excessive, it is nervous that corridor trampled by completion time of project length, line.
The increase-volume of existing transmission line of electricity has two kinds of methods: one is to strengthen conductor cross-section；Two is to use heat-resisting wire.Increasing is led
Line cross section requires to strengthen existing steel tower, uses heat-resisting wire then need not strengthen existing steel tower.With heat-resistant aluminium alloy material for leading
Electric layer has preferable market prospects plus aluminium Baogang cored structure as the wire improving current-carrying capacity.Heat-resisting aluminium alloy can make to lead
The operating temperature of line brings up to 150 DEG C from 70 DEG C, and current-carrying capacity also improves 0.6 times accordingly.
