Embodiment Construction
[0015] The present invention is further explained as follows with reference to accompanying drawing in conjunction with specific embodiment:
[0016] see figure 1 , the large-length flexible anode cable shown in the figure includes a circular conductor 1, which is formed by twisting 133 tinned round copper wires of φ0.36mm. The specific twisting method is: first, seven Tinned copper wires are twisted to form 1 strand, and a total of 19 strands are formed, and then 19 strands are twisted to form a circular conductor 1 . The twisted outer diameter of the circular conductor 1 is about φ5.8mm.
[0017] A layer of polymer conductive layer 2 is extruded outside the circular conductor 1, and the polymer conductive layer 2 is made of a black high-conductivity high polymer material with a volume resistivity not greater than 1.5Ω.cm, and the base material of the black high-conductivity high polymer material It can be one of polyethylene, polyvinyl chloride, and cross-linked polyethyle...

Abstract
The invention discloses a long flexible anode cable comprising a round conductor formed by stranding multiple tinned or non-tinned copper wires, a polymer conducting layer extruded on the round conductor, a particle carbon black layer uniformly coated on the polymer conducting layer, an acid-proof, alkali-proof, abrasion-proof and anti-corrosion fabric layer longitudinally covered outside the particle carbon black layer, and a high-strength abrasion-proof layer braided on the fabric layer. The long flexible anode cable has the advantages of long cable length, stable and uniform output current and convenience of construction, can be widely applied to anti-corrosion protection of metal pipelines or metal tanks, and is especially suitable for petroleum pipelines, gas pipelines, oil tanks and the like.
Description
Technical field: [0001] The invention relates to the technical field of cables, which have the characteristics of large length and bendability, and are widely used in large-length flexible anode cables for the protection of oil and natural gas metal pipelines and metal gas storage tanks. Background technique: [0002] At present, oil pipelines, natural gas pipelines and gas storage tanks are all made of steel containers, which are susceptible to chemical corrosion from the surrounding environment. Over time, they will be completely corroded and lose their application value, so protection must be implemented. [0003] At present, the sacrificial anode protection method is more common. There are two common methods of sacrificial anode protection: one is deep well anode protection, which requires special anode materials, and the cost is high and the construction is more cumbersome; the other is mesh anode protection, mainly It is suitable for short-distance protection such as g...
