Description
Technical field
The utility model is related to field of cable technology, and specifically a kind of cost is low, mechanical performance strong and water resistance
The good high waterproof railway cable of smooth aluminium set.
Background technology
In recent years, railway cable has requirements at the higher level to cable life, and the quality of block-water performance is influence cable life
Key factor, and mounting and installation environment is also increasingly severe, this certainly will need a kind of more stable stop water go solution this
One contradiction；The ground connection of existing railway cable structual shield and sheathed structure is improper to cause the problem of inner sheath punctures, and this
Problem seriously annoyings the line electricity person of making angry.
The content of the invention
The purpose of this utility model be the problem of presence for prior art there is provided a kind of cost is low, mechanical performance strong and
The high waterproof railway cable of the good smooth aluminium set of water resistance.
The purpose of this utility model is solved by the following technical programs：
A kind of high waterproof railway cable of smooth aluminium set, including conductor and be successively set on outside conductor conductor shield, absolutely
Edge layer, insulation screen, it is characterised in that：Described insulation screen is externally provided with buffer water-blocking band layer, buffer water-blocking band layer
Provided with wrapped aluminium strip, wrapped aluminium strip outside weld is connected to flat aluminium sheath, and flat aluminium sheath is externally provided with oversheath.
The thickness of the flat aluminium sheath is 8~4 with the thickness ratio of wrapped aluminium strip：1.
The wrapped clearance rate of the wrapped aluminium strip is 45%~50%.
Be provided with hot melt adhesive layer between described flat aluminium sheath and oversheath, hot melt adhesive layer cause flat aluminium sheath and oversheath it
Between tight bond and avoid relative slip.
The outer application graphite or extrusion semi-conductive layer of the oversheath are used as electrode.
Using the connection of copper shell during the metal part connection of the cable.
The utility model has the following advantages compared with prior art：
The utility model replaces shielding+sheathed structure by using flat aluminium sheath, can be in original carrying short circuit current flow
With mechanical external force action function it is constant in the case of, reduce cable cost, and the outside diameter of cable diminishes, weight, increases friendship
Goods length；By setting wrapped aluminium strip on semi-conductive buffer water-blocking band layer, the heat produced during the flat aluminium sheath of welding can be made
Spread as early as possible, protect fibre core, and the thickness ratio of the thickness of flat aluminium sheath and wrapped aluminium strip is 8~6：1, the rational proportion of thickness
So that excessive heat is distributed without influenceing cable fibre core, meet the different short circuit current flow demands of client, reduce cost.
The utility model plays anti-by extruding one layer of hot melt adhesive layer outside flat aluminium sheath come replacing asphalt or asphalt caulk
Corruption effect, and ensure to closely bond between flat aluminium sheath and the material of oversheath, be not in relative sliding phenomenon；By outside
Graphite is coated outside sheath or extrusion semi-conductive layer makees electrode, direct current can be carried out to the oversheath of cable after the completion of cable laying
Voltage test, with the oversheath of test cable whether in laid processes it is damaged.
The utility model replaces shielding+sheathed structure by using flat aluminium sheath, and improvement, which is laid, manufactures transition joint process,
The connection of cable metal part instead of tin-coated copper guipure by copper shell, and mechanical performance enhancing is electrically connected safer, water resistance
Increase.

Embodiment
The utility model is further described with embodiment below in conjunction with the accompanying drawings.
As shown in Figure 1：A kind of high waterproof railway cable of smooth aluminium set, including conductor 1 and it is successively set on leading outside conductor 1
Body screen layer 2, insulating barrier 3, insulation screen 4, buffer water-blocking band layer 5, buffer water-blocking band layer 5 are externally provided with insulation screen 4
Provided with the wrapped aluminium strip 6 that wrapped clearance rate is 45%~50%, the wrapped outside weld of aluminium strip 6 is connected to flat aluminium sheath 7, flat aluminium sheath 7
The thickness ratio of thickness and wrapped aluminium strip 6 is 8~4：1, it is externally provided with oversheath 9, the outer application of oversheath 9 in flat aluminium sheath 7
Graphite or extrusion semi-conductive layer 10 are used as electrode.On the basis of said structure, it is provided between flat aluminium sheath 7 and oversheath 9
Hot melt adhesive layer 8, hot melt adhesive layer 8 causes between flat aluminium sheath 7 and oversheath 9 tight bond and avoids relative slip.
In addition as shown in Fig. 2 replacing shielding+sheathed structure by using flat aluminium sheath 7, improvement, which is laid, manufactures transition joint
Process, the connection of cable metal part instead of tin-coated copper guipure by copper shell 11, and mechanical performance enhancing, electrical connection is safer,
