Description
Technical Field

Background
The insulation eccentricity of the power cable is an assessment index reflecting the processing capacity of insulation production, and the national standard GB/T12706 specifies that the insulation eccentricity of the cable is not more than 15%. The standard specifies that the insulation eccentricity is calculated as (insulation maximum thickness-insulation minimum thickness) ÷ insulation maximum thickness × 100% over the same cross-section. With the improvement of the performance index requirements of engineering projects, the insulation eccentricity of a high-quality cable required by the high-quality project is improved from no more than 15% of the national standard to no more than 6%, and the eccentricity of a more strict project is controlled to a level of no more than 5%.
At present, the insulation of the power cable produced by the prior art mainly adopts a three-layer co-extrusion and vulcanized tube crosslinking mode, and the production mode mainly comprises a catenary line (CCV) mode and a vertical tower (VCV) mode. The catenary wire (CCV) production type insulation extrusion mode and the vulcanization pipe crosslinking mode are catenary horizontal distribution, and insulation eccentricity is difficult to control due to the action of gravity in the high-temperature extrusion and vulcanization processes; although engineering technicians develop technologies such as an up-and-down rotary type traction and a down-traction thread twisting device on the basis of the existing CCV technology, due to the fact that span of two ends of a catenary is large, eccentricity is caused by gravity, and problems such as suspension shaking caused by equipment coordination exist, the eccentricity control level can only be guaranteed within 10% at present. The other vertical tower (VCV) production crosslinking mode is that the insulation extrusion and crosslinking modes are linearly and vertically arranged, so that the problem that the eccentricity of insulation caused by gravity and catenary jitter is difficult to control is well solved, the insulation eccentricity can be controlled within 5 percent, but the problems of high vertical tower cost, high construction safety risk, low production efficiency and the like caused by the short length of a vulcanized pipe due to height limitation are solved, and the vertical tower (VCV) production crosslinking mode is generally only applied to the production of high-voltage and ultrahigh-voltage cables with small market demand and higher technical level; for medium-pressure products with large market demands, the production is generally carried out in a catenary (CCV) mode.
