Description

A kind of stretch-proof flame-proof power cable

Technical field

The utility model relates to power cable technical field more particularly to a kind of stretch-proof flame-proof power cables.

Background technique

Power cable is the cable for being used for transmission and distributing electric energy, and power cable is usually used in Urban Underground power grid, power station Lead line, industrial and mining enterprises' in-line power and mistake river sea submarine transmission line, since power cable is in the basic routing line of electric system In transmitting and distribute the cable product of high-power power, including 1-500KV and more than various voltage class, working environment Badly, so insulation and flame-retardancy requirements to cable are higher than general cable, the power cable in currently available technology there is The defects of tensile resistance is general, poor flame retardant properties.

Utility model content

Purpose of the utility model is to solve existing in the prior art, power cable tensile resistance is general, anti-flammability The disadvantage of energy difference, and a kind of stretch-proof flame-proof power cable proposed.

To achieve the goals above, the utility model adopts the technical scheme that

A kind of stretch-proof flame-proof power cable, including core are designed, the core is wrapped with shielded layer, the shielded layer It is wrapped with silicone insulation layer, is socketed with Anti-slip cover outside the silicone insulation layer, the Anti-slip cover is specially silica gel sleeve pipe, and institute It states and is provided with limit hole inside Anti-slip cover, mica layer is socketed with outside the Anti-slip cover, between the Anti-slip cover and the mica layer Filled with aramid yarn layer, it is enclosed with liner layer outside the mica layer, is enclosed with oversheath outside the liner layer.

Preferably, the core is wound by multiply electric conductor, and the core matches with the limit pore size.

Preferably, inside the Anti-slip cover doped with wire, and the length of the length of the Anti-slip cover and the core Match.

Preferably, the mica layer is stacked by multilayer mica layer.

Preferably, the oversheath and liner layer are cross-linked polyethylene layer.

The utility model proposes a kind of stretch-proof flame-proof power cable, beneficial effect is:

1, by the silicone insulation layer wrapped up in core outsourcing, it can be improved the screening ability for improving cable, it is exhausted by silica gel The Anti-slip cover being socketed outside edge layer can be improved the ability to bear of cable core when being pullled by external force, to improve electric power electricity The tensile resistance of cable.

2, power cable can be improved by the aramid yarn layer filled between mica layer and mica layer and silicone insulation layer Flame retardant property and heat-resisting ability.

In figure: core 1, shielded layer 2, silicone insulation layer 3, aramid yarn layer 4, mica layer 5, liner layer 6, oversheath 7, anticreep Cover 8, limit hole 9.

Specific embodiment

The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole Embodiment.

Referring to Fig.1-3, a kind of stretch-proof flame-proof power cable, including core 1, core 1 are wound by multiply electric conductor, Core 1 is wrapped with shielded layer 2, and shielded layer 2 is wrapped with silicone insulation layer 3, is socketed with Anti-slip cover 8 outside silicone insulation layer 3, prevents It press-offs inside 8 doped with wire, and the length of Anti-slip cover 8 and the length of core 1 match, Anti-slip cover 8 is specially silica gel sheath Pipe, and limit hole 9 is provided with inside Anti-slip cover 8, core 1 matches with 9 size of limit hole, can be drawn in power cable by external force When pulling, that shares the receiving of core 1 pulls power, to improve the tensile resistance of power cable, while improving power cable and drawing Stretch the overall stability under environment.

Mica layer 5 is socketed with outside Anti-slip cover 8, mica layer 5 is stacked by multilayer mica layer, can be improved mica layer 5 Overall structural strength, and preferable flame retardant property can be provided for power cable, while being able to ascend the tension of power cable Performance and heat-resisting ability are stretched, aramid yarn layer 4 is filled between Anti-slip cover 8 and mica layer 5, is enclosed with liner outside mica layer 5 Layer 6 is enclosed with oversheath 7 outside liner layer 6, and oversheath 7 and liner layer 6 are cross-linked polyethylene layer.

The utility model can be improved the screening ability for improving cable by the silicone insulation layer 3 wrapped up outside core 1, It can be improved the ability to bear of cable core 1 when being pullled by external force by the Anti-slip cover 8 being socketed outside silicone insulation layer 3, To improve the tensile resistance of power cable, pass through the virtue filled between mica layer 5 and mica layer 5 and silicone insulation layer 3 Synthetic fibre yarn layer 4 can be improved the flame retardant property and heat-resisting ability of power cable.

The preferable specific embodiment of the above, only the utility model, but the protection scope of the utility model is not It is confined to this, anyone skilled in the art is within the technical scope disclosed by the utility model, practical according to this Novel technical solution and its utility model design are subject to equivalent substitution or change, should all cover the protection model in the utility model Within enclosing.
