Abstract
The utility model relates to an aluminium or an aluminium alloy twisted wire with a fibre reniforced composite material core. The outer layer is made of the traditional aluminium or the aluminum alloy twisted wires, a cable composite material core is made of fibre reniforced composite materials, the cable has the characteristics of large quantity of diversion and lightning strike resistance, and the steel core in the traditional steel core aluminium or the aluminium alloy twisted wires is replaced by the composite materials. Compared with the traditional steel core, the novel composite material core has lighter specific gravity and higher intensity, because the composite material core has the characteristics of non-conduction of electricity and magnetism, the rising temperature is smaller when the cable operates with a load bearing and conductivity is increased, and the utility model can bear a larger current-carrying capacity. The aluminium or aluminium alloy twisted wires on the outer layer of the utility model meet the demands of relative standards in China or foreign countries, and the composite materials have various shapes of round shape, multi-wire twisted wire shape, multi-wire sector shape, multi-wire hollow sector shape, tubular shape, etc.
Description
One, technical field
The utility model belongs to electric power and carries with electric power and distribution cable, the i.e. power cable of high-pressure delivery circuit.Especially fibre reinforced composites core aluminium and aluminium alloy stranded conductor
Two, background technology
Electric power handling cable commonly used at present is steel reinforced aluminium conductor or steel core aluminium alloy stranded conductor.For the continuous growth of power consumption, much build circuit and reached its utmost carrying ability, need to change its original circuit and enlarge its water conservancy diversion amount by the net sectional area that increases cable.This dilatation way needs to have now that iron tower is reinforced or build new large-scale iron tower in addition adapts to the cable that deadweight increases, this not only will increase cable and build the cost that supports iron tower, simultaneously also because the increase of cable deadweight and volume has also increased the insecurity in the cable running.In addition, the anti-thunderbolt of steel core aluminium (or aluminium alloy) twisted wire poor performance is simultaneously for from great and be unfavorable for the large span track laying.
Three, summary of the invention
This point with novel purpose is: the cable that the big and anti-thunderbolt of a kind of lightweight, water conservancy diversion amount is provided, using this cable not only to make the existing iron tower of utilization carry out electric power carries dilatation and guarantees that circuit operation reliability becomes possibility, and for its intensity height, in light weight, the large span that is specially adapted to China Duo Hu, river, river, territory, mountain region circuit is laid.When this cable was made hollow type, this cable also can carry optical cable simultaneously.
The technical scheme in the invention for solving the technical problem is: make the strengthening core of cable center with the steel core that fibre-reinforced composite core replaces in steel core aluminium (or aluminium alloy) twisted wire.
Further improvement of the utility model is: the skin of composite core goes out many aluminium (alloy) silk to be formed, and internal layer is a fibre reinforced materials.
This composite material proportion is little, intensity is high, nonmagnetic and non-conductive.The proportion of composite material according to the difference of selected raw material make its specific gravity control at 1.4 gram/cubic centimetres to 2.1 gram/cubic centimetres, tensile strength is controlled at 1000MPa to 2000MPa, compares not only with steel core that weight alleviates greatly, intensity also increases.Nonmagnetic and non-conductive for this composite material, this material and outer aluminium (or aluminium alloy) twisted wire do not have galvanomagnetic effect when cable carries, can make temperature remain on low state when making the cable operation, the reduction of operating temperature just whole cable conductance increases, and can bear bigger ampacity.
The beneficial effects of the utility model are, can replace the purpose that traditional steel core aluminium (or lead alloy) twisted wire reaches the delivery circuit dilatation, improves safety in operation and can carry out the big leap of circuit, the hollow composite material core can carry optical cable, can carry out the construction of electric power optical cable network simultaneously.
