Description
Technical field
The utility model relates to a kind of high-tension cable totally enclosed type steel drawing head.
Background technology
In electrical installation project, existing cable laying construction plan will consider the factors such as environmental condition, system of laying, product technology data.In high pressure, extra-high-tension cable cable laying operation, intake when effectively preventing cable from laying in cable trough, be that cable factory needs the long-term problem solved, traditional Novel high-voltage cable drawing head adopts steel, after melting, cable and single core cable tracting head is linked together with plumbous or tin.Plumbous, tin envelope in use can not bear large pulling force, and in use procedure, lead sealing can be ftractureed and be come off, and when there being water in cable trough, can cause high-tension cable inner inlet, and with the drawing head of full aluminum, and the high and tractive effort of cost is restricted.
Summary of the invention
The technical problems to be solved in the utility model is to provide one in use can meet comparatively large traction, prevents water inlet in use, and high-tension cable totally enclosed type steel drawing head easy to make.
For solving the problems of the technologies described above, the utility model is by the following technical solutions: a kind of high-tension cable totally enclosed type steel drawing head, comprise cable conductor, oversheath, corrugated aluminium sheath, drawing head body and traction hanging ring screw, the inside of described drawing head body is provided with a steel aluminium hydraulic pressed connecting pipe, one end of steel aluminium hydraulic pressed connecting pipe is connected with drawing head body, and the other end of steel aluminium hydraulic pressed connecting pipe crimps with the cable conductor of corresponding specification; The outer setting of described steel aluminium hydraulic pressed connecting pipe has one section of galvanized steel vestlet, and one end of galvanized steel vestlet is connected by molten soldering T-Ring with corrugated aluminium sheath, and the other end is connected with drawing head body by argon arc welding T-Ring.
Steel aluminium hydraulic pressed connecting pipe described in the utility model and drawing head body are linked by spiral shell and connect.
Insulating barrier is provided with in galvanized steel vestlet described in the utility model.
Heat-shrink tube is provided with outside galvanized steel vestlet described in the utility model.
Traction hanging ring screw described in the utility model screws in the head of drawing head body.
The utility model compared with prior art, in use can avoid because of bending or pulling force is excessive and cause the slicker solder of original drawing head technology to seal breaking, ftracture, the problem such as cable inner inlet, thus effectively guarantee cable installation and service quality; Simultaneously, adopt molten Welding technology, avoid adopting plumbous or tin welding between corrugated aluminium and coating steel pipe two kinds of different metals in making drawing head engineering, save resource, also greatly reduce drawing head cost of manufacture simultaneously, to cable manufacturer, user and society, all there is good economic benefits and social benefit.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail: as shown in Figure 1, the utility model high-tension cable totally enclosed type steel drawing head, comprise cable conductor 1, oversheath 2, corrugated aluminium sheath 3, drawing head body 10 and traction hanging ring screw 11, wherein, the inside of drawing head body 10 is provided with a steel aluminium hydraulic pressed connecting pipe 8, one end of steel aluminium hydraulic pressed connecting pipe 8 is connected with drawing head body 10, and the other end of steel aluminium hydraulic pressed connecting pipe 8 crimps with the cable conductor 1 of corresponding specification; Meanwhile, the outer setting of steel aluminium hydraulic pressed connecting pipe 8 has one section of galvanized steel vestlet 5, and one end of galvanized steel vestlet 5 is connected by molten soldering T-Ring 4 with corrugated aluminium sheath 3, and the other end is connected with drawing head body 10 by argon arc welding T-Ring 9.
Steel aluminium hydraulic pressed connecting pipe 8 of the present utility model is connected by spiral shell button (i.e. turn buckle) with drawing head body 10, is provided with insulating barrier 7 in galvanized steel vestlet 5, is provided with heat-shrink tube 6 outside galvanized steel vestlet 5, and traction hanging ring screw 11 screws in the head of drawing head body 10.
When the utility model makes, first overlap a cover High Strength Steel pipe outward at high voltage single-core cable, divest the insulating barrier of cable jacket, corrugated aluminium sheath and cable, expose cable conductor.The steel aluminium hydraulic pressed connecting pipe of a cylindrical shape is installed at drawing head center, and this aluminium hydraulic pressed connecting pipe one end and steel drawing head body spiral shell link and connect.Insert the single-core high-voltage cable conductor of corresponding specification in other end adapter, and this cable conductor and steel aluminium hydraulic pressed connecting pipe hydraulic tongs are compressed.Put galvanized steel vestlet after compression, one end of galvanized steel vestlet is welded with the corrugated aluminium sheath of cable with molten soldering T-Ring.The other end and the argon arc welding of cable steel drawing head body of galvanized steel vestlet are welded.Finally at the outer setting heat-shrink tube of cable, the head of high strength drawing head body screws in traction hanging ring screw with bolt.
In above-mentioned drawing head, steel traction aluminium hydraulic pressed connecting pipe, galvanized steel vestlet, steel drawing head body all adopt high strength steel material, the molten Welding of galvanized steel vestlet and corrugated aluminium sheath one end, the other end and drawing head body argon arc welding are integrated, and the drawing head after making meets tractive effort needs when high-tension cable lays.Adopt molten soldering to connect to be adopt low melting point aluminium to melt, to keep galvanized steel to be solid-state simultaneously, sprawl the connection forming lap joint and realize between metallic aluminium cover with galvanized steel by molten aluminum moistening.
Be with the insulating barrier of cable outside cable conductor, outside the insulating barrier of this cable, have corrugated aluminium sheath and oversheath.High strength steel drawing head body interior be connected with tubular steel aluminium hydraulic pressed connecting pipe with between cable conductor, high strength steel drawing head outside is connected with steel cage pipe, cable ripple aluminium sheath respectively with argon arc welding, molten soldering respectively.Compare with the welded cable drawing head of aluminum pipe argon arc welding with traditional lead, tin seal structure, in use pulling force improves greatly, the molten Welding technology simultaneously used, avoid to make in drawing head engineering and use metallic lead and noble metal tin, avoid metallic lead and tin to the pollution of environment, improve the intensity of drawing head, saved cost, and more convenient operation, there is good economic and social benefit to user and society.
