Description
Technical field
The utility model relates to a kind of cable, particularly a kind of cold-resistant tension mine special cable.
Background technology
Mine cable refers to ground installation in coal mining operation and underground equipment electric wire cable product.Along with the development of society, the requirement of user to cable performance is more and more higher, to the requirement of the power cable of mine too.Because Minepit environment is severe, such as north of china in winter weather extreme cold, also has borehole cable mobility strong, often colliding frequently in pullling, so cable must have winter resistance, pull resistance and resistance to wear.Traditional cable pull resistance is low, useful life is short, can not meet cold-resistant requirement.
Therefore, how improving the winter resistance of cable, pull resistance and resistance to wear, is the current technical issues that need to address of those skilled in the art.
Summary of the invention
The utility model provides a kind of cold-resistant tension mine special cable, solves current mining cable winter resistance, pull resistance, the problem that wears no resistance, and reduces the harm that cable causes environment.
For solving the problems of the technologies described above, the utility model adopts following technical scheme:
A kind of cold-resistant tension mine special cable, comprises the sheath of multiply cable core and coated cable core, is provided with waterstop and armour between described sheath and cable core
This waterstop described is semiconductor waterstop, and armour is that the conjunction of 0.5mm zinc plated mild carbon steel skein silk is formed by many diameters.
Described cable core comprises copper conductor, semi-conductive adhesive strap, cable core insulating barrier and braid.
Described cable core insulating barrier is ethylene propylene rubber insulated layer, and described braid is tincopper fuse wire braided armor.
Aluminosilicate refractory fiber cotton is filled with in space between described cable core and waterstop 2.
Magnesium oxide or aluminium hydroxide micro powder is provided with in described aluminosilicate refractory fiber cotton.
Stranded reinforcement is provided with in the space that described multiply cable core is adjacent.
Described stranded reinforcement forms by multi reinforcements is stranded, is coated with reinforcement insulating barrier outside reinforcement.
Traction-resistant fibre bundle is provided with in space between described cable core and stranded reinforcement.
Described sheath is polyvinyl chloride and thermoplastic elastomer blending modification sheath.
The beneficial effects of the utility model:
The utility model is provided with multiple tensile layer, makes cable have more mechanicalness, and the utility model also has the features such as opposing extreme cold, fire line, water proofing property, can also extend the useful life of cable, improve the security performance of cable.
Accompanying drawing explanation
Fig. 1 is overall structure schematic diagram of the present utility model;
In figure, 1-armour, 2-waterstop, 3-braid, 4-copper conductor, 5-semi-conductive adhesive strap, 6-aluminosilicate refractory fiber is cotton, 7-traction-resistant fibre bundle, 8-reinforcement, 9-reinforcement insulating barrier, 10-cable core insulating barrier.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further detailed, with reference to the one cold-resistant tension mine special cable shown in figure 1, comprises the sheath 11 of cable core and this cable core coated, between described sheath 11 and cable core, be provided with waterstop 2 and armour 1; Described waterstop 2 is semiconductor waterstop 2, and armour 1 is that 0.5mm zinc plated mild carbon steel skein silk closes by many diameters; Described cable core is made up of copper conductor 4, semi-conductive adhesive strap 5, cable core insulating barrier 10 and braid 3, and described cable core insulating barrier 10 is ethylene propylene rubber insulated layer, and braid 3 is tincopper fuse wire braided armor.Be filled with aluminosilicate refractory fiber cotton 6 in space between cable core and waterstop 2, in described aluminosilicate refractory fiber cotton 6, be provided with magnesium oxide or aluminium hydroxide micro powder; Be provided with stranded reinforcement in space between described multiply cable core is adjacent, this stranded reinforcement has that multi reinforcements 8 is stranded to be formed, and is coated with reinforcement insulating barrier 9 outside reinforcement 8; Traction-resistant fibre bundle 7 is provided with in space between described cable core and stranded reinforcement; Described sheath 11 is polyvinyl chloride and thermoplastic elastomer blending modification sheath;
Waterstop 2 of the present utility model is partly lead waterstop.Partly lead waterstop and there is the anti-creeping function of waterproof, partly lead waterstop and can better ensure the tight and firm of the construction of cable.
The sheath 11 of cable of the present utility model is polyvinyl chloride and thermoplastic elastomer blending modification sheath, and sheath 11 at minimum-37 DEG C, can use under the condition of mean temperature-23 DEG C.
The utility model is provided with multiple tensile layer, makes cable have more mechanicalness, and the utility model also has the features such as nonhazardous, fire line, water proofing property and winter resistance, extends the useful life of cable, improves the security performance of cable.
Content of the present utility model is not limited to cited by embodiment, and the conversion of those of ordinary skill in the art by reading the utility model specification to any equivalence that technical solutions of the utility model are taked, is claim of the present utility model and contains.
