Abstract
A colored indicating live wire pipe relates to an electrical conduit. The colored indicating live wire pipe comprises a live wire pipe fitting, and is characterized in that the outer layer of the live wire pipe fitting adopts a colored indicating layer, and the colored indicating layer is orange. The orange-colored indicating layer has an excellent warning effect, and can warn people approaching or touching the live wire to mind through a color, thereby lowering the possibility of the contact of the human body and the live wire under non precaution measures, and further reducing the hazard of electric shock.
Description
Technical field
The utility model relates to the used for transmission line pipe, is specifically related to electrical casing pipe.
Background technology
In the general transmission line, hot voltage is higher, causes electric shock when the people contacts easily.And in use, the collapse situation of waist of breach, centre appears in the live wire pipe of parcel live wire easily, in case live wire and zero line bump, resistance between two contact points is zero no better than, at this moment electric current is very big, contact point place at live wire and zero line can produce heat, may cause short circuit to the plain conductor scorification.To produce serious influence after the short circuit, and, cause tripping operation to influence equipment work etc. such as circuit initiation fire on fire.
And when electric wire connects up, because two strands of electric wire surface structures of drawing are identical, so before energising, be difficult to distinguish Live line Zero line.Because it is too big to distinguish the difficulty of Live line Zero line, the installation work personnel often have to abandon distinguishing Live line Zero line when wiring.Do not distinguish Live line Zero line during wiring, though little to customer impact when normally using, there are potential hazard and unnecessary additional energy consumption.Should connect live wire such as switch contact,, then can after cutting off switch, still can have high voltage if connection is zero line.
The utility model content
The purpose of this utility model is, provides a kind of coloured sign live wire pipe, to address the above problem.
The technical problem that the utility model solved can realize by the following technical solutions:
Coloured sign live wire pipe comprises a live wire pipe pipe fitting, it is characterized in that, described live wire pipe pipe fitting skin is a coloured marking layer, and described coloured marking layer is orange.Coloured sign live wire pipe itself just has the effect of parcel live wire, the electric shock hidden danger that can avoid live wire to expose bringing.The more important thing is and orangely can give soft, warm sensation eye-catching the time, therefore being orange coloured marking layer has good warning function, can by color prompting near or the people that touch live wire take care, thereby reduced under the no precautionary measures human body and live wire contact may, and then reduced the danger of getting an electric shock.
Be embedded with the resistance oxygen reinforced layer of an employing oxygen barrier material in described coloured sign live wire pipe.Oxygen barrier material can reduce the transmitance of oxygen effectively, thereby reduces the oxidation rate of live wire, slows down the aging speed of live wire, prolongs the life-span of live wire.
Also be embedded with the flame-retardant layer of an employing flame-retardant material in described coloured sign live wire pipe.The flame-retardant layer has the characteristic of flame-retardant, when fire takes place, can avoid the intensity of a fire to spread along pipeline effectively, can also effectively protect internal wiring safety.
Also be embedded with a glass layer that constitutes by glass fibre in described coloured sign live wire pipe.Glass layer has been strengthened the intensity of coloured sign live wire pipe, has improved the live wire waist situation of collapsing in use, the fail safe that has improved transmission line.Increased the pressure-bearing scope of coloured sign live wire pipe simultaneously, reduced of the requirement of coloured sign live wire pipe environment for use, can bright dress or secretly spread in the concrete.
Description of drawings
Fig. 1 is the structural representation of coloured sign live wire pipe.
Embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose with effect is easy to understand, below in conjunction with the further elaboration the utility model of concrete diagram.
With reference to Fig. 1, coloured sign live wire pipe comprises a live wire pipe pipe fitting, and live wire pipe pipe fitting skin is a coloured marking layer 2 that serves as warning.The color of coloured marking layer 2 can be selected the shades of colour except that white, grey for use, as, redness, yellow, blueness etc. are as long as can play sign.Owing to orangely can give soft, warm sensation eye-catching the time, so the color of coloured marking layer 2 is preferably orange.
For live wire pipe pipe fitting internal layer 1, color can be chosen wantonly, but in order to make coloured sign live wire pipe more attractive in appearance on the whole, generous, the color of live wire pipe pipe fitting internal layer 1 and the solid colour of coloured marking layer 2.If coloured marking layer 2 is orange, so coloured sign live wire pipe adopts and is orange live wire pipe pipe fitting internal layer 1.Certainly, sometimes in order to increase contrast, live wire pipe pipe fitting internal layer 1 can adopt one to play the color of contrast effect with the color of coloured marking layer 2.In addition, in order to reduce processing step, reduce production costs, live wire pipe pipe fitting internal layer 1 and coloured marking layer 2 can unite two into one, and promptly directly produce to have the live wire pipe pipe fitting internal layer 1 of color, and are equipped with look marking layer 2 no longer in addition.
In order to improve the performance of coloured sign live wire pipe, can also bury various functional layers underground in coloured sign live wire pipe, as resistance oxygen reinforced layer, flame-retardant layer, glass layer.Resistance oxygen reinforced layer adopts oxygen barrier material, as EVOH, PVDC etc.The flame-retardant layer adopts the flame-retardant material, as high temperature resistant elastomer plastic, the fire-retardant green material of expansion type low-smoke halogen-free etc.Glass layer is made of glass fibre, can adopt glass mat, also glass fibre directly can be sneaked into.
More than show and described basic principle of the present utility model and principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; that describes in the foregoing description and the specification just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
