Abstract
The utility model discloses a color-marked neutral wire tube, relating to the bushing. The color-marked neutral wire tube comprises a neutral tube fitting; the outer layer of the neutral wire tube fitting is a color-marked layer, the color mark is blue. The blue mark has good effect for identification, the wiring operator can easily distinguish the neutral wire from the live wire according to the color-marked neutral wire tube, thereby the wiring difficulty is reduced, unnecessary energy consumption is further reduced and the energy is saved.
Description
Technical field
The utility model relates to the used for transmission line pipe, is specifically related to electrical casing pipe.
Background technology
Zero line in use the collapse situation of waist of breach, centre occurs easily.In case and live wire and zero line bump, the resistance between two contact points no better than zero, electric current at this moment is very big, can produce heat at the contact point place of live wire and zero line, 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.
But 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 zero line pipe, to address the above problem.
The technical problem that the utility model solved can realize by the following technical solutions:
Coloured sign zero line pipe comprises a zero line pipe pipe fitting, it is characterized in that, described zero line pipe pipe fitting skin is a coloured marking layer, and it is blue that described coloured marking layer is.Can give beautiful, pure and fresh, quiet, open-minded, sedate sensation when blueness is eye-catching, therefore be blue coloured marking layer and have good marked effect, the installation work personnel can distinguish zero line and live wire easily by coloured sign zero line pipe, reduce the wiring difficulty, and then reduce unnecessary energy consumption, energy savings.
Be embedded with the resistance oxygen reinforced layer of an employing oxygen barrier material in described coloured sign zero line pipe.Oxygen barrier material can reduce the transmitance of oxygen effectively, thereby reduces the oxidation rate of zero line, slows down the aging speed of zero line, prolongs the life-span of zero line.
Also be embedded with the flame-retardant layer of an employing flame-retardant material in described coloured sign zero line 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 zero line pipe.Glass layer has been strengthened the intensity of coloured sign zero line pipe, has improved the zero line waist situation of collapsing in use, the fail safe that has improved transmission line.Increased the pressure-bearing scope of coloured sign zero line pipe simultaneously, reduced of the requirement of coloured sign zero line 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 zero line 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 zero line pipe comprises a zero line pipe pipe fitting, and zero line pipe pipe fitting skin is coloured marking layer 2 of marked effect together.The color of coloured marking layer 2 can be selected the shades of colour except that white, grey for use, as, redness, yellow, green etc. are as long as can play sign.Owing to can give beautiful, pure and fresh, quiet, open-minded, sedate sensation when blueness is eye-catching, the color of coloured marking layer 2 is preferably blue.
For zero line pipe pipe fitting internal layer 1, color can be chosen wantonly, but in order to make coloured sign zero line pipe more attractive in appearance on the whole, generous, the color of zero line pipe pipe fitting internal layer 1 and the solid colour of coloured marking layer 2.If it is blue that coloured marking layer 2 is, so coloured sign zero line pipe adopts the zero line pipe pipe fitting internal layer 1 that is blue.Certainly, sometimes in order to increase contrast, zero line 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, zero line pipe pipe fitting internal layer 1 and coloured marking layer 2 can unite two into one, and promptly directly produce to have the zero line 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 zero line pipe, can also bury various functional layers underground in coloured sign zero line 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.
