and carrying out multi-layer regular stranding on the stranded wires, and compacting the result obtained by each layer of regular stranding to obtain at least one first conductor and a plurality of second conductors.
Specifically, in order to meet the use environments of seawater, salt mist and the like of the underwater monitoring cable, the first conductor and the second conductor are required to have strong corrosion resistance, the first conductor and the second conductor can be preferably prepared from tin-plated soft copper materials, and the continuity of the plating layer is required to meet quality indexes. In the embodiment of the utility model, a high-quality oxygen-free copper rod is adopted, the copper content reaches 99.99%, and the conductivity can reach 101% IACS. The direct-reading metal spectrum analyzer is used for quantitatively measuring the chemical content of various elements of copper and copper alloy, and the cable is ensured to have excellent conductivity. And carrying out metal spectrum measurement on each batch of material copper conductors to ensure the quality stability of the material copper conductors.
The tin plating process of the bare copper conductor is strictly controlled, copper wire tin plating is mainly divided into two modes of electroplating and hot plating, the plating thickness of the electroplating process is generally between 1 and 24 mu m, even the range is larger, the plating thickness of the hot plating process is between 0.5 and 2 mu m, and the control is relatively accurate, so that the hot plating process is adopted for the tin plating of the underwater monitoring cable. Copper conductor tinning is carried out by adopting cloud tin with the purity of 99.99 percent, and the thickness of the tin layer is accurately controlled by controlling the proportion of a tinning mould and a single wire diameter, the temperature of the tin, the wire winding speed and the like, so that the uniformity and the continuity of the tin layer are ensured.
Since the bend radius of the underwater monitoring cable is required to be 4 times, the structure of the first conductor and the second conductor is required to be higher. (1) selection of monofilaments: the elongation of the single filament of the tinned soft copper wire is not less than 20%. The smaller the diameter of the filaments, the more the number of filaments, the softer the filaments, and the softer the twisted conductor. (2) design of twisting direction: the process of using the same-direction stranding of the conductors of the cable is applied by using the frequent movement of the cable of the electric welding machine, the conductors are stranded in the same direction, and the stranded wire stranding and the compound stranding are all left-direction (S stranding). The stranded finished conductor is compact, smooth in surface and very good in flexibility, and gaps among stranded wires after the stranded conductor is stranded in different directions are effectively avoided. (3) arrangement of stranded wire structures: the twisted wire compound twisting adopts a 1+6+12 normal twisting mode, so that the structural stability of the monitoring cable is improved, and the influence of easy deformation of the same-direction bundle twisting result is reduced. (4) Pitch design: according to the requirements of the first conductor and the second conductor of the monitoring cable, the pitch diameter ratio of the stranded wires and the normal stranding results of each layer is reasonably designed, the pitch of the normal stranding results of each layer is determined, the pitch of the normal stranding results is reduced as much as possible, and the flexibility of the first conductor and the second conductor is enhanced. (5) mold selection: the advantage of the same-direction stranding is that the flexibility is good, the stranding is suitable for frequent movement and use, and the disadvantage is that the stranding is unstable in structure and easy to deform in the subsequent production process. In order to prevent the caterpillar band from flattening the conductors in the insulation production process when preparing the first conductor and the second conductor of the underwater monitoring cable, the result obtained by normal stranding is compressed to a certain extent when each layer of stranding, and a proper die is selected to ensure that the conductors are compact in structure and not easy to deform. Meanwhile, the outer diameter of the compressed conductor can be reduced by 0.05mm, so that the outer diameter of the monitoring cable is effectively reduced, and the weight of the monitoring cable is reduced.
