Description
Technical field
The utility model is related to power cable technical field, specially a kind of high-strength aluminum alloy power cable.
Background technology
Typically by several or several groups of wires（Every group at least two）The cable of stranded similar rope, every group of wire
Between mutually insulated, and be often twisted into around a center, whole outside is surrounded by the coating of high-insulation.Cable has interior logical
Electricity, the feature of external insulation.Cable has power cable, control cable, compensating cable, shielded cable, high-temperature cable, calculating electromechanical
Cable, signal cable, coaxial cable, fire-resisting cable, cable for ship, mine cable, aluminium alloy cable etc..They are all by sub-thread
Or stranded conductor and insulating barrier composition, for connecting circuit, electrical equipment etc..
China's copper resource is relatively poor, and bauxite resource is relatively rich, in power cable manufacturing technology, for copper is one with aluminium
Individual long-term strategic task.Aluminium alloy cable substitutes copper cable, it is possible to reduce the weight of cable, while correspondingly reduction is mounted to
This, reduces the abrasion of equipment and cable.But, the low strength of aluminium alloy cable, cable is during installation and use, easily
Damaged by the impact of external force, increase cable maintenance cost, in some instances it may even be possible to cause electric leakage accident.
Utility model content
The purpose of this utility model is to provide a kind of high-strength aluminum alloy power cable, to solve in above-mentioned background technology
The problem of proposition.
To achieve the above object, the utility model provides following technical scheme：
A kind of high-strength aluminum alloy power cable, including overcoat, metal net layer, flame retardant coating, keel shoe and core, keel
Some necks are uniformly provided with frame, all necks are helically wound on keel shoe, neck is deep-slotted chip breaker, neck is embedded
Provided with core, core includes aluminium alloy conductor and insulating barrier, if aluminium alloy conductor is by the carried interest anaerobic annealing ultra-fine soft aluminium of nickel plating
Silk is stranded to be formed, and insulating barrier is arranged with outside aluminium alloy conductor；Provided with buffer fillings layer between the outside of keel shoe and core, fill out
The outer sheath for filling cushion is provided with flame retardant coating, and the outer sheath of flame retardant coating is provided with metal net layer, and the outer sheath of metal net layer is provided with anti-
