Background
At present, most of domestic ultrahigh-voltage cables are produced by a cross-linking vertical tower type production line, the cross-linking production is generally produced by a continuous production mode, the machine is started for 5-6 days generally in one week, the length of a single cabled wire core is generally not more than 1.5 kilometers, and the insulated wire core can be efficiently produced. At present, most of China adopts a connection mode of two conductor wire cores to enter a crosslinking unit to produce an insulated wire core.
The majority of the existing manufacturers adopt cross-linked conductors as cross connectors, and the cross connectors are convenient to process during production at present, but have some problems in use. Firstly, the external processing is needed when the whole set of die is processed, the external processing cost is higher, and the processing period is longer; secondly, when two single conductor wire cores are connected, the assembly process is complicated, the assembly sequence is that the upper die 1 and the die 2 are firstly installed on the two sections of conductors, and the cross buckle rod is installed after the die 1 and the die 2 are installed; thirdly, when the cross buckle rod is installed, if the clamping grooves of the two molds are not symmetrical, the joint of one mold needs to be pulled, so that the clamping grooves of the two molds correspond to the cross buckle, and then the two bolts are connected; when the bolt is connected, the conductor needs to be twisted manually when the two die clamping grooves are asymmetric, a larger rigid elastic force can be generated in the conductor while the conductor is twisted, the rigid elastic force of the cabling core of the conductor with a relatively small cross section is smaller, and the requirement on operators is relatively lower, for example, when a cable with a large cross section is produced, the rigid elastic force generated when the cable conductor with a large cross section is twisted by pulling is larger in the cross section of the cable conductor, more operators are needed, the operation is inconvenient, and 3-4 persons are generally needed; fifthly, after connection, when the cable core enters the cross-linking unit, the conductor can twist in the movement process to deform, and the eccentricity of the produced cross-linking core is greatly influenced.
