Abstract
The utility model relates to a chemical corrosion resistant, waterproof and anti-interference control instrument cable and belongs to the technical field of cables. The cable comprises a wrapping belt, a shielding layer and a jacket arranged on a cable core cabled by an insulating wire core in sequence; and a methyl silicate water blocking layer is arranged between the shielding layer and the jacket. The insulating wire core is made of GB/T9330-2008 polyvinyl chloride or crosslinked polyethylene extruded and wrapped on Types 5 and 6 conductors conforming to the GB/T3956-2008 requirements. The shielding layer adopts a copper wire braided layer. The jacket is made of GB/T5023-2008 silicon rubber. The utility model has the advantages of reasonable and simple structure, easy production and manufacture, low cost and good use performance. The water blocking layer is made of methyl silicate, and the maximal moisture absorption and expansion coefficient (free state) thereof is 60 percent. The jacket is made of the silicon rubber, thereby having stronger chemical corrosion resistance. After being laid, the cable has a certain water blocking effect, thereby voiding the occurrence of a series of accidents caused by moisture.
Description
Technical field
The utility model relates to the structure of the anti-interference control instrument cable of a kind of resistance to chemical attack waterproof, has the certain decay resistance and the structure of water resistance especially, belongs to the technical field of cable.
Background technology
The control instrument cable that is called as " nerve " of automation is made huge contribution for human modernization, the electric property that it is good, physical and mechanical properties, chemical stability, therefore, this cable is used widely, control cable is used for large-scale automation control system mostly, as power plant, petroleum and petrochemical industry, unmanned substation etc., these cable layings are in air, because airborne steam can enter into the electrical property that cable influences cable, gently then can form the network discharge, heavy then can cause cable short circuit, China's southern area particularly.The annual accident that takes place thus causes heavy losses for China's economy.
The utility model content
The purpose of this utility model is exactly to overcome the deficiency that above-mentioned existing cable exists, a kind of have good electric property, physical and mechanical properties, chemical stability are provided, have decay resistance and waterproof interference free performance again, be fit to the anti-interference control instrument cable of resistance to chemical attack waterproof that use the high humid area of moisture content.
The purpose of this utility model is to realize like this, the anti-interference control instrument cable of resistance to chemical attack waterproof, comprise the band, screen and the sheath that set gradually on the cable core by the insulated wire cores stranding, it is characterized in that between screen and sheath, being provided with the methyl silicate water blocking layer.
Described insulated wire cores constitutes by extruding the polyvinyl chloride or the crosslinked polyethylene that meet GB/T9330-2008 on the 5th class that meets the GB/T3956-2008 requirement, the 6th class conductor.
Described screen is the copper wire braid.
The material of described sheath is the silicon rubber that meets GB/T5023-2008.
The utility model is rational in infrastructure simple, manufactures easily, and cost is low, and serviceability is good.Conductor adopts and meets the GB/T3956-2008 material, and cable is the 5th class, the 6th class conductor of soft junction structure.Insulation is adopted and to be met the polyvinyl chloride stipulated among the GB/T9330-2008 or the requirement of cross-linking polyethylene materials.The copper wire braiding is adopted in shielding, and performance meets the requirement of GB/T9330-2008.Water blocking layer adopts methyl silicate.Maximum moisture expantion coefficient (free situation) is 60%.Sheath adopts silicon rubber to have stronger resistance to chemical corrosion, has certain resistance effect after this cable laying, has avoided the generation because of moisture-induced a series of accidents.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
1 conductor, 2 insulating barriers, 3 bands, 4 screens, 5 water blocking layers, 6 sheaths among the figure.
Embodiment
As Fig. 1: conductor 1 adopts the 5th class, the 6th class material among the GB/T3956-2008, extruded insulation layer 2 constitutes insulated wire cores outside conductor 1, insulating material adopts the polyvinyl chloride or the crosslinked polyethylene of GB/9330-2008 regulation, with wrapped band 3 behind the insulated wire cores stranding, the braiding copper wire constitutes screen 4 outside band 3, outside screen 4, be coated with bag one deck methyl silicate water blocking layer 5, outside methyl silicate water blocking layer 5, extrude the silicone rubber jacket 6 that meets GB/T5023-2008, make the anti-interference control instrument cable of resistance to chemical attack waterproof.
Claims (4)
