Abstract
The utility model discloses a cable used for a reference electrode of an impressed current cathodic protection system. The cable comprises a conductor; tinned copper wires, alloy wires and an aramid fiber wire are twisted jointly and are bunched so as to form the conductor; the exterior of the conductor is coated with an ethylene propylene rubber insulated layer; the exterior of the ethylene propylene rubber insulated layer is sequentially coated with an aluminum and plastic composite band-wrapped inner shielding layer and a copper wire-braided outer shielding layer; the exterior of the outer shielding layer is coated with a polyester wire-braided tear-resistant layer; and the exterior of the tear-resistant layer is coated with a thermoplastic low-smoke halogen-free elastomer sheath layer. The tinned copper wires, the alloy wires and the aramid fiber wire are twisted jointly and are bunched so as to form the conductor of the cable of the utility model, such that the structural strength of the conductor is improved, and core fracture will not appear anymore; and therefore, anti-interference shielding performance, insulation performance and environmental performance of the cable are all improved.
Description
Technical field:
The utility model relates to cable, relates in particular to a kind of impressed current cathodic protection system reference electrode cable.
Background technology:
Buried steel pipe-line or oil gas storage tank etc. generally all adopt impressed current cathodic protection system in case electrochemical corrosion causes heavy losses.Cathodic protection system is made up of DC power supply (potentiostat), auxiliary anode, protected negative electrode, reference electrode.DC power supply (potentiostat) negative pole is connected with protected negative electrode steel pipe or storage tank by cable; DC power supply (potentiostat) is anodal to be connected with auxiliary anode by cable; auxiliary anode and steel pipe or storage tank applied add protective current and regulate size of current automatically; make steel pipe or jar maintenance negative potential (negative electrodeization); reference electrode is connected with potentiostat with to current potential Monitoring and Controlling in addition by cable; thereby significantly reduce the generation of steel pipe or storage tank, prolonged steel pipe or storage tank life-span because of the electrochemical corrosion perforation.
For steel pipe-line or the used cable of oil gas storage tank impressed current cathodic protection system potentiostat reference electrode is common polyvinyl chloride insulation pvc sheath shielded flexible cable (RVVP type), the used RVVP type cable of impressed current cathodic protection system potentiostat reference electrode of the prior art exists weak point: cable core is easily broken, has only single copper wire braid shielded, the shielding interference free performance is relatively poor, cannot say for sure during test that data are accurate; Polyvinyl chloride no matter is as insulation or sheath material uses, and because of containing halogen and heavy metal, all is unfavorable for environmental protection; In addition, the polyvinyl chloride insulation working temperature generally has only 70 ℃, and humidity resistance is also relatively poor.
The utility model content:
In order to remedy the prior art problem, the purpose of this utility model provides a kind of impressed current cathodic protection system reference electrode cable, and is rational in infrastructure, improves cable conductor intensity, shielding properties, humidity resistance, environmental-protecting performance.
The technical solution of the utility model is as follows:
Impressed current cathodic protection system reference electrode cable; comprise conductor; it is characterized in that: described conductor adopts the common stranded bunchy of tinned copper wire, alloy silk and aramid fiber silk to constitute; described conductor is coated with ethylene propylene rubber insulated layer; the outer internal shield of the wrapped formation of aluminium-plastic tape, the outer shielding layer that the copper wire braiding constitutes of being coated with successively of ethylene propylene rubber insulated layer; outer shielding layer is coated with the tear resistant layer that the dacron thread braiding constitutes, and tear resistant layer is coated with thermoplastic low-smoke halide-free elastic body jacket layer.
Described impressed current cathodic protection system reference electrode cable is characterized in that: described alloy silk can be selected Contra wire for use.
The utility model has the advantages that:
1, conductor design: conductor adopts the common stranded bunchy of tinned copper wire, alloy silk and aramid fiber silk to constitute, and improves conductor structure intensity, and disconnected core phenomenon is not occurring.
2, composite shielding design: behind the wrapped aluminium-plastic tape of insulated wire cores, carry out the copper wire braiding, shield and be double-deck combining structure, the shielding interference free performance is better, thereby guarantees that test data is more accurate.
3, insulating Design: insulating material is selected Halogen ethylene-propylene rubber for use, and its electric property, humidity resistance all are better than polyvinyl chloride, and working temperature is also high 20 ℃ than polyvinyl chloride.
4, feature of environmental protection design: select insulating material Halogen ethylene-propylene rubber for use, sheath material thermoplastic low-smoke halide-free elastomer is all not halogen-containing and heavy metal, Halogen, low cigarette, nontoxic, meeting ROHS instruction (being limited in the instruction of using harmful substance in the electronic and electrical equipment), is Green Product.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
Embodiment:
Referring to Fig. 1:
Impressed current cathodic protection system reference electrode cable; comprise conductor; conductor adopts tinned copper wire 1; alloy silk 2 and aramid fiber silk 3 common stranded bunchys constitute; improve conductor structure intensity; disconnected core phenomenon is not occurring; conductor is coated with ethylene propylene rubber insulated layer 4; the ethylene propylene rubber insulated layer 4 outer internal shield 5 that is coated with the wrapped formation of aluminium-plastic tape successively; the outer shielding layer 6 that the copper wire braiding constitutes; double-deck combination shielding construction; the shielding interference free performance is better; thereby guarantee that test data is more accurate, outer shielding layer 6 is coated with the tear resistant layer 7 that the dacron thread braiding constitutes, and tear resistant layer 7 is coated with thermoplastic low-smoke halide-free elastic body jacket layer 8.
Alloy silk 2 can be selected Contra wire for use.
