Abstract
The utility model relates to a cable hanging head serving as a special hanging device when a power cable is vertically installed. A conductive body core wire of the power cable is penetrated through a connector. After the connector is pressed and connected by hydraulic machinery and the pressed and connected connector is fastened to a hanging ring all together by a fastening screw, the assemblage of the interior structure members of the cable hanging head is finished. On an injection machine, the insulating sheath materials of the hanging head is injected and encapsulated by an assembled cable hanging head assembly.
Description
Affiliated technical field
The utility model belongs to the power cable field.
Background technology
Cable hanging head in the known technology is at cable socket outsourcing heat-shrinkable T bush or other insulating material, is woven into net with materials such as steel wires then, is enclosed within the outside also strand of insulating material tightly.Another part of net is made the suspension ring shape, hangs and is hanging on the utensil, as skyscraper or the interim load-supporting part before final clamping is fastening of power cable under the occasion vertically is installed.
Its defective is:
Very easily cause injury to insulation, and the bearing capacity deficiency, installation is absolutely unsafe.
The utility model content
The purpose of this utility model is:
Directly will hang head makes the respective carrier ability, can not injure insulation and the lifting of comparatively safe power cable with hanging head.
Realize method of the present utility model:
Internal part and the outside part of hanging all adopt the rigid material that enough bearing capacitys are arranged, by the rigid insulation material of sufficient intensity is arranged, directly and the leader cable conductor core wire be connected as one.
Advantage of the present utility model is:
There are enough dielectric strengths and enough rigidity in inside, and enough bearing capacitys are arranged, and can not injure the outer layer insulation of cable, and installation is safe ready very again.
Good effect of the present utility model is:
Effectively improve the operational reliability of power cable; Shorten the time of installation; Reduce labour intensity and operating expenses.
Description of drawings
Now, the utility model is done detailed explanation with the embodiment of accompanying drawing.
Fig. 1 is a cable hanging head external form schematic diagram;
Fig. 2 is A----A section----the cable internal structure schematic diagram among Fig. 1.
Among Fig. 1, Fig. 21 is hoisting ring for hoisting end of cable; 2 are the cable hanging head outer layer insulation sheath after the injection mo(u)lding; 3 is the cable outer layer insulating sleeve; 4 is cable inner conductor heart yearn; 5 is the connector of cable conductor heart yearn and suspension ring 1; 6 is joint bolt; 7 are the indent after compressing; 8 is that hoisting ring for hoisting end of cable is hanging the inner metal part of head.
Specific implementation method
Now with the embodiment of accompanying drawing, the implementation process of its cable hanging head is elaborated:
Cable socket is peelled off the appropriate section sheath and insulated 3, and conductor core wire 4 penetrates in the bottom endoporus in the connector 5, by particular manufacturing craft and hydraulic test, compresses 4 and 5, and 7 for compressing the ring indent that the back occurs on 5.Again suspension ring 1 are snapped onto in 5 the upper opening groove, penetrate in 5 and 1 fastening with screw 6.The head that hangs that will assemble is at last put into injection mold, will hang insulating sleeve material 2 injection moulding and seal and finish on injection molding machine.The insulating sleeve 2 that hangs of sealing injection moulding has sufficiently long overlap distance with cable outer layer insulating sleeve 3, and guarantee that cable hanging head insulating sleeve and cable outer layer insulating sleeve are in the scope of overlap joint, effectively bond together mutually, thus insulation property and the reliable watertightness and the air-tightness of guaranteeing to hang head.So far illustrate that the utility model fabrication techniques is finished hangs head, can be widely used in prefabricated branch cable and other various power cables as the head of hanging when installing and using that hangs.
Implement the best approach of the present utility model:
On the professional production line, make of particular manufacturing craft, equipment.
