Abstract

The utility model relates to the cable field, particularly to an aluminium based ceramic fiber core aluminium alloy lead which is applicable to the compatibilization or capacity expanding reconstruction of the high voltage power transmission and distribution circuit under the condition that the current rod tower is unchanged. The aluminium based ceramic fiber core aluminium alloy lead comprises a reinforcement core, an aluminium alloy foil, and a conductor, wherein the aluminium alloy foil wraps the external surface of the reinforcement core by winding; the reinforcement core is composed of a plurality of aluminium-based ceramic fiber cores; and the conductor comprises a plurality of round wires, with the round wires intertwisted upon the external surface of the aluminium alloy foil. The aluminium based ceramic fiber core aluminium alloy lead can fully realize the compatibilization and the improvement of conveying capability under the condition that the current electrical network power transmission line rod tower is unchanged, that is, the aluminium based ceramic fiber core aluminium alloy lead can fully meet the demand for high electrical performance, high mechanical property, low sag corrosion resistance, and long-term lifetime performance. Meanwhile, the cost and the time for electrical network reconstruction are reduced.

Description

Al-base ceramic fibre core aluminium alloy conductor
Technical field
The utility model belongs to field of cables, specifically is to be applicable to the increase-volume of high pressure electric line under the constant condition of existing shaft tower or the Al-base ceramic fibre core aluminium alloy conductor of extending capacity reformation.
Background technology
Along with growing continuously and fast of China's economy, the increasing demand of electric power is increased, electricity shortage has become the bottleneck of restriction economic development, and is particularly outstanding in the developed area, and the transmission capacity that improves electrical network just becomes and presses for.But build new transmission line not only invest huge, the construction period is long; And receive the restriction of environmental protection; Open up new circuit corridor difficulty in the nervous area of land used also very big; Therefore, the transmission capacity that how to improve existing overhead transmission line has very realistic economic meaning, existing steel reinforced aluminium conductor from great, ampacity is low, sag greatly, not corrosion-resistant.
Summary of the invention
The utility model to the existing steel reinforced aluminium conductor that exists in the above-mentioned technology from great, ampacity is low, sag greatly, not corrosion-resistant etc. shortcoming; Propose a kind of Al-base ceramic fibre core aluminium alloy conductor, it has deadweight lightweight, big leap, elevated operating temperature and ampacity, low arc drop, high strength and corrosion resistant characteristics.
The technical scheme that realizes the utility model purpose is following:
Al-base ceramic fibre core aluminium alloy conductor; It comprises strengthening core, alloy foil and conductor, the wrapped outer surface that wraps in strengthening core of alloy foil, and strengthening core is made up of some Al-base ceramic fibre cores; Conductor comprises some round lines, and these circle lines are stranded in the outer surface of alloy foil.
Described Al-base ceramic fibre core comprises aluminium base and some ceramic fibres, some ceramic fibres embed vertically aluminium base in.
Described round line draws hard circle line for containing the zirconium heat-resisting aluminium alloy.
The beneficial effect of the utility model be this Al-base ceramic fibre core aluminium alloy conductor satisfy fully realize under the constant condition of existing grid power transmission overhead line structures increase-volume with promote conveying capacity to high electrical property, high-mechanical property, the low arc drop of lead corrosion-resistant and long term life performance demands; Simultaneously can reduce the electric network reconstruction cost again, the shortening time.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Embodiment
As shown in Figure 1; Al-base ceramic fibre core aluminium alloy conductor; It comprises strengthening core, alloy foil and conductor, the alloy foil 2 wrapped outer surfaces that wrap in strengthening core, and strengthening core is made up of some Al-base ceramic fibre cores 1; Conductor comprises some round lines 3, and these circle lines 3 are stranded in the outer surface of alloy foil 2.
Wherein, The strengthening core manufacturing approach is that strengthening core adopts Al-base ceramic fibre core 1 through alloy alloy foil 2 wrapped forming; Al-base ceramic fibre core 1 comprises aluminium base and some ceramic fibres; Some ceramic fibres embed vertically aluminium base in, promptly up to ten thousand ultra-fine high-strength ceramic fibers are embedded into compounded Al-base ceramic fiber in the raffinal along the lead equidirectional.
Wherein, circle line 3 draws hard circle line for containing the zirconium heat-resisting aluminium alloy, and the conductor manufacturing approach is that conductor adopts and contains the zirconium heat-resisting aluminium alloy and draw that hard round line is stranded forms.
