Abstract
The utility model discloses a direct current dust removal cable, including conductor, insulating layer, semiconduction area, iron shielded layer, non -woven fabrics band, interior sheath, armor and outer jacket, the insulating layer is crowded altogether by conductor screen, XLPE insulation and insulation shielding three -layer and is constituteed. The utility model has the characteristics of bending property excellence, stable, the clean environmental protection of electrical property, dry -type crosslinked do not have the greasy dirt, do not lay simple to operate and life cycle length etc.
Description
Technical field
This utility model relates to direct current cables, particularly to a kind of direct current dedusting cable.
Background technology
Along with the development of state fundamental construction and perfect, governments at all levels occupy living environment the people creating a cleaning, environmental protection and grace and work and be placed on critical role.Rapidly growing for electric dust removing system construction and the transformation project of iron and steel, cement, generating and environmental protection relevant industries.
Electric cleaner is by high voltage direct current, maintains an electrostatic field that be enough to make gas ionization, and zwitterion adsorbs and makes dust obtain electric charge.Electric charge dust, under the effect of electric field force, just runs to the electrode that electric polarity is contrary and is deposited on electrode.Making dust fall people bottom ash bucket by means of vibration body, purified gas is just discharged to top from cylinder, can reach dust and separates with gas and reach dust removing effects and purpose.
Existing be connected with its electric cleaner supporting electric precipitation cable be use oil-impregnated paper insulation direct current cables, its bending property, electrical property can not meet the requirement of user.
Utility model content
The purpose of this utility model is to provide the crosslinking of a kind of bending property excellence, electric performance stablity, clean environment firendly, dry type without greasy dirt, laying installation convenience and the direct current dedusting cable using the features such as cycle length.
To achieve these goals, the technical solution of the utility model is as follows:
A kind of direct current dedusting cable, it is characterised in that: include conductor, insulating barrier, semi-conductive tape, metal screen layer, non-woven fabrics band, sheath, armor and outer jacket；Described insulating barrier is insulated by conductor shielding, XLPE and insulation shielding is three-layer co-extruded forms.
Further, described semi-conductive tape thickness 0.3mm, overlapping wrapped on core, Duplication is 15～20%.
Further, described metal screen layer selects the copper wire of high connductivity to be wound around and copper strips is dredged around shielding, and screening factor is little, and shield effectiveness is good.
Further, described armor uses stainless steel silk and strengthens non-woven fabrics band, has the feature of corrosion resistance and good and good bending property.
After have employed technique scheme, this utility model has the advantages that employing three-layer co-extruded dry type crosslinking production technology, and cable performance is stable, discharge off phenomenon；Using copper wire to be wound around and copper strips is dredged around shielding construction, screening factor is 0.01, and shield effectiveness is excellent；Use stainless steel silk and strengthen non-woven fabrics band armouring, there is the feature of corrosion resistance and good and good bending property.
Feature of the present utility model see graphic and the most preferably embodiment the detailed description of this case and obtains and be well understood to.
Accompanying drawing explanation
Fig. 1 is cross section structure schematic diagram of the present utility model.
Detailed description of the invention
For the technological means making this utility model realize, creation characteristic, reach purpose and be easy to understand with effect, this utility model is expanded on further below in conjunction with specific embodiment.
As it is shown in figure 1, a kind of direct current dedusting cable, including conductor (1), insulating barrier (2), semi-conductive tape (3), metal screen layer (4), non-woven fabrics band (5), sheath (6), armor (7) and outer jacket (8)；Described insulating barrier (2) is by conductor shielding (21), XLPE(crosslinked polyethylene) insulation (22) and insulation shielding (23) is three-layer co-extruded forms.Described semi-conductive tape (3) selects thickness 0.3mm, and overlapping wrapped on core, Duplication is 15～20%.Described metal screen layer (4) selects the copper wire of high connductivity to be wound around and copper strips is dredged around shielding, and screening factor is little, and shield effectiveness is good.Described armor (7) uses stainless steel silk and strengthens non-woven fabrics band, has the feature of corrosion resistance and good and good bending property.
This utility model uses environment to be HVDC distribution loop, as electric power connection line between rectifier transformer and electric cleaner, is suitable for iron and steel, cement, generating and the electric precipitation place of environmental protection relevant industries.
Of the present utility model ultimate principle, principal character and of the present utility model advantage have more than been shown and described.Skilled person will appreciate that of the industry; this utility model is not restricted to the described embodiments; simply principle of the present utility model described in above-described embodiment and description; on the premise of without departing from this utility model spirit and scope, this utility model also has various changes and modifications, and these changes and improvements both fall within the range of claimed this utility model.The protection domain that this utility model requires is defined by appending claims and equivalent thereof.
Claims (4)
1. a direct current dedusting cable, including conductor (1), insulating barrier (2), semi-conductive tape (3), metal screen layer (4), non-woven fabrics band (5), sheath (6), armor (7) and outer jacket (8)；Described insulating barrier (2) is insulated (22) by conductor shielding (21), XLPE and insulation shielding (23) is three-layer co-extruded forms.
