Abstract
The utility model provides a tension-resistant conductor clamp for aluminum conductor steel-reinforced (ACSR), which solves the problem that a conductor and a tension-resistant conductor clamp, which are not firmly connected together at a conductor outlet, are easily worn. The tension-resistant conductor clamp for ACSR comprises a steel anchor, an aluminum-alloy pipe, a drainage plate and a drainage conductor clamp. The aluminum-alloy pipe is sleeved on the steel anchor and is connected with the steel anchor through pressure welding. The drainage plate is sleeved on the aluminum-alloy pipe and is in bolt connection with the drainage conductor clamp. The conductor outlet of the aluminum-alloy pipe is in an arc-shaped chamfering shape. The length of a drawing pin at one side of the conductor outlet of the aluminum-alloy pipe is greater than the diameter of the ACSR. The tension-resistant conductor clamp has the advantages of simple structure and convenient installation. Thus, the technical requirements on the connection of ACSR with the tension-resistant conductor clamp can be satisfied.
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, when setting up wire, must be equipped with strain clamp and come anchoring, clamping aluminium alloy core, therefore needs strain clamp can bear larger pulling force.Existing steel core aluminum alloy stranded wire also exists aluminium-alloy pipe that holding of aluminium alloy stranded conductor puted forth effort not force to get the problems such as connection is insecure, and the line outlet wire is easy impaired with strain clamp.
Summary of the invention
The utility model provides a kind of steel reinforced aluminium conductor strain clamp, has solved the line outlet wire and has been connected problem insecure, that wire weares and teares easily with strain clamp.
For achieving the above object, the utility model is taked following technical scheme:
The steel reinforced aluminium conductor strain clamp, comprise steel anchor, aluminium-alloy pipe, drainage plate and conduction wire clamp, aluminium-alloy pipe is enclosed within on the steel anchor and is crimped on the steel anchor, drainage plate is socketed on the aluminium-alloy pipe, drainage plate is connected with the conduction wire clamp bolt, the line outlet of aluminium-alloy pipe is the circular arc chamfering shape, and the taper length of line outlet one side of aluminium-alloy pipe is greater than the diameter of steel reinforced aluminium conductor.
When steel reinforced aluminium conductor is connected with strain clamp, the steel core crimping of steel anchor and steel reinforced aluminium conductor, the aluminium alloy stranded conductor crimping of aluminium-alloy pipe and steel reinforced aluminium conductor, and be hydraulic connecting, both by producing under pressure plastic deformation, thereby be combined as a whole with steel core and aluminium alloy stranded conductor respectively.The line outlet of aluminium-alloy pipe adopts circular arc chamfering, has avoided stress to concentrate, and has reduced the wearing and tearing of wire, has prolonged the wire life-span.The taper length of aluminium-alloy pipe is greater than the diameter of steel reinforced aluminium conductor, and contact area increases, holds and put forth effort to strengthen, so that crimping is firm when making steel reinforced aluminium conductor and aluminium-alloy pipe crimping.
The steel anchor is formed by connecting by draw ring and steel pipe, and aluminium-alloy pipe is crimped on the steel pipe.
The drainage angle of conduction wire clamp can be 0 °, can also be 30 °.
The utility model is simple in structure, easy for installation, satisfies the specification requirement that strain clamp connects steel reinforced aluminium conductor.
