Description
Technical field
The utility model relates to electricity field, particularly relates to a kind of ceramic silica gel cable.
Background technology
Along with the development of society, power consumption also increases thereupon, requires that the current capacity of cable is increasing, and the conductor wire core cross section of cable constantly increases, and the unit weight of cable also increases thereupon day by day.Some are had to the specific environment of fire resistant requirements, mainly through ensureing its fire resistance at conductor outer setting flame retardant coating.Existing cable mainly adopts magnesium oxide mineral or mica to be used as flame retardant coating.But produce the equipment of magnesium oxide mineral fire-proof insulation cable costly, fund input is large especially, and the bending radius of this type of cable is comparatively large, in the processes such as the laying installation of production and processing, transport, circuit and use, there is requirement special.Adopt the fire-resisting cable that mica tape makes, in process of production, need multi-lay winding, due to the restriction of process conditions, often cause overlapping the slot place easily to occur overlapping defect, add the easy embrittlement of mica tape after burning, come off, reduce fire-resistant effect to a great extent, cause line short, thus be difficult to ensure communication, electric power in the case of fire safe and smooth.
Utility model content
The purpose of this utility model is to provide a kind of ceramic silica gel cable, possesses high fire resistance, and overcomes the high cost of existing flame retardant coating, caducous problem.
In order to achieve the above object, the utility model provides following technical scheme:
A kind of ceramic silica gel cable, cable core comprises cable conductor, mica after-combustion layer, core ceramic silicone insulation layer from the inside to surface successively, and the outside of cable core sets gradually fiber-filled layer, ceramic silica gel sheath, copper pipe oversheath.Core ceramic silicone insulation layer and ceramic silica gel sheath can form the protective layer of hard ceramic when high temperature, play isolated burning things which may cause a fire disaster, fireproofing function, improve fire resistance of the present utility model.
Further, also comprise positioner, positioner is arranged on the outside of copper pipe oversheath.Cable, when laying, needs to be fixed on other equipment or certain position sometimes, makes the utility model convenient fixing by positioner.
Further, positioner comprises location notch and connecting band, and location notch is arranged on the outside of copper pipe oversheath, and connecting band is connected with location notch.In use, be fixed on by connecting band on other cables or equipment, connecting band gets up location notch and other cables or equipment connection, realizes location of the present utility model and fixes.
Further, also comprise rib, rib is arranged on the outside of copper pipe sheath.The phenomenon of twisting the group of being coiled between cable can be there is when cable is too much, long.By rib, the utility model is wound around along rib, there will not be and twist the group of being coiled into.
Further, cable core is the one in single core, twin-core, three cores, four-core and five cores.
Further, cable conductor is aluminium alloy conductor.
Further, the thickness of core ceramic silicone insulation layer, ceramic silica gel sheath is not less than 3mm, to ensure that the thickness of ceramic silica gel effectively can completely cut off burning things which may cause a fire disaster.
The beneficial effects of the utility model are:
1) core ceramic silicone insulation layer and ceramic silica gel sheath can form the protective layer of hard ceramic when high temperature, play isolated burning things which may cause a fire disaster, fireproofing function, improve fire resistance of the present utility model;
2) positioner is convenient is fixed on other equipment by the utility model;
3) by rib, the utility model is wound around along rib, there will not be and twist the group of being coiled into.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, comes for those of ordinary skill in the art
Say, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
