Background technique
At present；Suspension clamp, wire clamp is widely used in the fixation of high pressure and extra high voltage network Large-diameter Steel core aluminum stranded wire
Shell generally uses steel or aluminum, will need fixed steel-cored aluminium strand, is placed in wire clamp shell, passes through U-bolt, crimping pad
Block；Steel-cored aluminium strand is fixed in wire clamp shell, is then hung over below insulator by lifting lug, due to fixed point distance
It is long, route weight is big, steel-cored aluminium strand and wire clamp both ends contact site stress it is very big, in two termination contact of top crimping cushion block
Also stress, since long-term wind vibrates, wave, bend, stress point aluminum steel can wear injured, long-time contact point position aluminium wire
Material meeting fatigue strength reduces, and the generation for the phenomenon for causing aluminum conductor stranded influences transmission line safety operation.
Summary of the invention
The purpose of this utility model is to be directed to；High pressure and extra high voltage network, Large-diameter Steel core aluminum stranded wire pendency at present
Fixing clamper, to the status of steel-cored aluminium strand damage, and provide；It can prevent the abrasion of steel-cored aluminium strand, extend steel-core-aluminium strand
The line service life, a kind of suspension clamp for electric line.
Technical solution adopted by the utility model to solve its technical problems is；By placing polytetrafluoroethylene (PTFE) in wire clamp shell
Casing, be placed above crimping cushion block, U-bolt pass through from top to bottom fastening nut, by crimping cushion block, teflon sleeve with
The fastening of wire clamp cage connection, then lifting lug is fitted together and formed by standing screw and lifting lug fixture nut, wherein poly- four
Vinyl fluoride casing tube internal hole is longitudinally provided with slot, corresponding surface open-ended slot longitudinally cuts with opening, is coated on steel-cored aluminium strand with facilitating
Face, the production of teflon sleeve inner wall have burr, and teflon sleeve is at least 2 times longer than wire clamp shell bottom, wire clamp shell,
Teflon sleeve cooperates with corresponding standard line footpath, manufactures the series of products of adaptation, wire clamp shell, crimping cushion block, lifting lug
It is all made of cast steel manufacture, hot galvanizing later carries out anti-corrosion.
When the utility model is installed and used；Teflon sleeve is peeled off first, is inserted in and is intended to fixed steel-cored aluminium strand
Above, make to be open in the direction of left or right, teflon sleeve both ends are tightened with clamp, are put into wire clamp shell, then will
The lifting lug being connected to below insulator is fixed together by lifting lug standing screw and lifting lug fixture nut with wire clamp shell, is adjusted
Whole good position；Crimping cushion block is put into, two U-bolts are by fastening nut, the steel core for having coated teflon sleeve
Aluminum stranded conductor is closely joined together with wire clamp shell.
The utility model has the beneficial effects that: due to using high-intensitive and flexible teflon sleeve, packet
The pendency force part for covering steel-cored aluminium strand makes steel-cored aluminium strand avoid the abrasion for being swung, bending and being subject to due to wind, by
In teflon sleeve effect, make the stress fatigue elongated segment of steel-cored aluminium strand, substantially increase making for steel-cored aluminium strand
With the service life, the safe operation of transmission line of electricity is effectively guaranteed.

Specific embodiment
The utility model includes in attached drawing: by placing teflon sleeve 2, teflon sleeve 2 in wire clamp shell 1
Be placed above crimping cushion block 4, U-bolt 5 from top to bottom, by fastening nut 6, by crimping cushion block 4, teflon sleeve 2
It is connect with wire clamp shell 1, then fits together and formed by lifting lug 7, by lifting lug standing screw 8 and lifting lug fixture nut 14,
Wherein 2 inner hole of teflon sleeve is longitudinally provided with slot 9 and open-ended slot 10, cuts with opening 11 in 10 longitudinal direction of open-ended slot, gathers
The production of 2 inner wall of tetrafluoroethene casing has burr 12, and teflon sleeve 2 is at least 2 times longer than wire clamp shell bottom, wire clamp shell 1,
