The internal diameter of the first heat-shrinkable T bush and the second heat-shrinkable T bush is than cable or the large 3 ~ 8mm of migration equipment external diameter, and length is 210 ~ 280mm.
Second heat-shrinkable T bush 25mm longer than the length of the first heat-shrinkable T bush.
The power cable migration equipment that the utility model provides, beneficial effect is as follows:
1, can be combined with cable conductor after aluminium hydraulic pressed connecting pipe crimping; be threaded connection between traction cap and aluminium hydraulic pressed connecting pipe; cable slippage when preventing unwrapping wire; be combined with the conductor of power cable by aluminium hydraulic pressed connecting pipe and traction cap; formed and stablize overall structure; cable is when moving; force localization is on this migration equipment; power cable insulation can be solved and be easily destroyed the problem with water proofing property difference; first heat-shrinkable T bush is enclosed with the structure of protective layer and the second heat-shrinkable T bush outward successively, and can prevent cable from intaking, water-tight performance is good; tensile strength is large, can bear pulling force >=100kN.
2, parts are few, and processing is simple, and water-tight performance is good, and intensity is large.
3, easy for installation, simply, save the set-up time, accelerate installation rate.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is described in further detail:
Fig. 1 is the utility model structural representation.
Embodiment
As shown in Figure 1; a kind of power cable migration equipment; aluminium hydraulic pressed connecting pipe 1 is provided with the screw thread matched with traction cap 2; the internal diameter of traction cap 2 matches with the external diameter of aluminium hydraulic pressed connecting pipe 1; traction cap 2 front end is closed, and its blind end 2-1 is installed with suspension ring 4, and the first heat-shrinkable T bush 5 is located at traction cap 2 with outside power cable 8 oversheath; first heat-shrinkable T bush 5 is outer is enclosed with protective layer 6 and the second heat-shrinkable T bush 7 successively, and protective layer 6 is made up of layer glass silk ribbon and the epoxy resin layer be coated in outside glass tape.
The internal diameter of the first heat-shrinkable T bush 5 and the second heat-shrinkable T bush 7 is than cable or the large 3 ~ 8mm of migration equipment external diameter, and length is 210 ~ 280mm.
The long 25mm of length of the second heat-shrinkable T bush 7 to the first heat-shrinkable T bush 5.
It is of the present utility model that to install and use process as follows:
1, wire stripping:
Peel the long oversheath of the outside termination 150mm of power cable 8 and other material off, expose cable core, the plane of structure of strip off wants neat, again so that cable core to be as the criterion by the tangent plane peeling oversheath and other material off, reserve 25mm, peel the outer shielding layer of cable core remainder, insulating barrier and internal shield, expose conductor thread core 3, should note not scratching conductor thread core 3, and ensure that tangent plane is smooth.
2, wiring:
Conductor thread core 3 is loaded in aluminium hydraulic pressed connecting pipe 1, makes the end contact of insulated wire cores end face and aluminium hydraulic pressed connecting pipe 1.
3, line ball:
After installing line, with pressing tongs, aluminium hydraulic pressed connecting pipe 1 is pressed on conductor thread core 3, first compress with larger jaw, firm with the jaw crimping be applicable to again, press from the straight tube place of aluminium hydraulic pressed connecting pipe 1 thread root during crimping, pressing length is 55 ~ 65mm, and to compress, rounding is as the criterion (aluminium hydraulic pressed connecting pipe distance threaded distal end have an appointment the length of 15mm, do not press).After pressing, the part that conductor thread core 3 grows the crimping mouth of pipe cuts off.After having pressed line, at the two ends of aluminium hydraulic pressed connecting pipe 1 and conductive cable contacts place coated glass glue, should prevent into water.
4, install:
The aluminium hydraulic pressed connecting pipe 1 pressed and power cable 8 are loaded in traction cap 2, the oversheath of power cable 8 and the tangent plane of other material should with the end contact of traction cap 2, gap can not more than 2 ~ 5mm.
5, seal protection:
Be the surface of outer sheath scraping (having graphite linings should being wiped off of graphite linings) of 110 ~ 140mm by power cable 8 length, be beneficial to the sealing of heat-shrinkable T bush.By the glass cement coating sealing of the end contact place of aluminium hydraulic pressed connecting pipe 1, traction cap 2 and power cable 8, and with self-adhesive tape, the gap place self-adhesive tape of the end face of power cable 8 end face and aluminium hydraulic pressed connecting pipe 1, traction cap 2 is wound around closely, cable and aluminium hydraulic pressed connecting pipe 1 can not be made, the contact position of traction cap 2 intakes.
6, first heat-shrinkable T bush 5 and the second heat-shrinkable T bush 7 be installed:
Entangle the oversheath of traction cap 2 and power cable 8 with the first heat-shrinkable T bush 5, make the center of the first heat-shrinkable T bush 5 be located at the contact position of power cable 8 oversheath and traction cap 2, then homogeneous heating plastic packaging is lived.At the overlapping wrapped layer glass silk ribbon of the first heat-shrinkable T bush 5 outer surface, and surface-coated one deck epoxy resin, form protective layer, make from power cable 8 mechanical external force.Then at protective layer outer surface the second heat-shrinkable T bush 7 plastic packaging, the long 25mm of length of the second heat-shrinkable T bush 7 to the first heat-shrinkable T bush 5, namely completes installation of the present utility model.
During use, adopt pulling equipment to pull suspension ring 4, the migration of power cable 8 can be completed.
