Abstract
The utility model provides a lead splicing sleeve matching with a high-strength steel-core aluminum-alloy stranded wire. The splicing sleeve for the high-strength steel-core aluminum-alloy stranded wire comprises an aluminum pipe and a steel pipe. The aluminum pipe is sleeved on the steel pipe. An aluminum-alloy stranded wire and a steel core of the steel-core aluminum-alloy stranded wire are respectively butted against the aluminum pipe and the steel pipe in a hydraulic manner, thereby making the aluminum pipe and the steel pipe coaxial. The splicing sleeve is simple in structure and convenient to mount, and meets the technical requirements on the splicing sleeve for the steel-core aluminum-alloy stranded wire.
Description
Technical field
The utility model relates to a kind of for the splicing fitting on the large capacity transmission circuit.
Background technology
Electric armour clamp will stand to ice on the transmission line of long-time running, the baptism of snow, storm, strong wind, sleet, icing easily cause the faults such as wire ice-shedding, phase fault, wire collision lightning conducter, so electric armour clamp must possess higher mechanical strength and enough coefficient of safetys.Steel core aluminum alloy stranded wire is applicable to the built on stilts large open-wire transmission line road of crossing over power transmission lines, large span or heavy ice snow, its lead splicing sleeve is used for two terminals of overhead transmission line conductor, except bearing the whole pulling force of wire, also as the electric conductor conduction current, it is the important gold utensil in the transmission line, because all being the strand system, the steel core of steel core aluminum alloy stranded wire part and aluminium alloy part form, and twisted wire internal arrangement mode is complicated, so need a kind of splicing sleeve that matches with steel core aluminum alloy stranded wire to be beneficial to the crimping of twisted wire.
Summary of the invention
The utility model provides a kind of lead splicing sleeve that matches with high-strength steel core aluminum alloy stranded wire.
For achieving the above object, the utility model is taked following technical scheme:
A kind of high-strength steel core aluminum alloy stranded wire splicing sleeve is made of aluminum pipe and steel pipe, aluminium pipe sleeve on steel pipe, the aluminium alloy stranded conductor of steel core aluminum alloy stranded wire and steel core dock with aluminum pipe and steel pipe hydraulic pressure respectively form aluminum pipe and steel pipe coaxial.
The aluminum pipe of splicing sleeve is used for the aluminium alloy stranded conductor part crimping with steel core aluminum alloy stranded wire, steel pipe is used for the steel core part crimping with steel core aluminum alloy stranded wire, and both adopt the mode of hydraulic pressure docking, hydraulic pressure continues and has enough mechanical strengths and good electrical contact performance.Aluminum pipe and steel pipe produce plastic deformation under pressure, thereby are combined as a whole with aluminium alloy stranded conductor and steel core twisted wire respectively.
The taper length at aluminum pipe two ends is 100mm, and the taper angle at aluminum pipe two ends is 4 °.Aluminum pipe length is 1260mm, and external diameter is 76mm, and internal diameter is 43mm; Steel pipe length is 280mm, and external diameter is 28mm, and internal diameter is 12.1mm.Aluminum pipe is made by 6063 aluminium alloys, and steel pipe is made by the Q235A steel.Concentrate for fear of aluminum pipe and steel pipe exit stress, the mouth of pipe of aluminum pipe and steel pipe is provided with circular arc chamfering.
The utility model is simple in structure, easy for installation, has satisfied the specification requirement that is used for the splicing sleeve of steel core aluminum alloy stranded wire.
