Several Factors Affecting the Speed of Cross - Link Production Line

Several Factors Affecting the Speed of Cross - Link Production Line

Production line speed refers to the speed of the core in the sulfide tube, the higher the line speed, the higher the production efficiency, but it is subject to the following factors.

(A) Cable specifications: high rated voltage, that is, thick insulation thickness, cable cross-section, under the restrictions of glue quantity by extruder, more mainly is by the restriction of  cross-linking speed, the line speed can not be too high.

(B) The temperature and water cooling water: lower water temperature , high water level are good for cooling, but the negative effect on the speed of cross-linking. Therefore, we should choose a reasonable water temperature and water level, it is necessary to ensure that the cross-linked degree requirements, but also to ensure cooling requirement. For different specifications of the cable, water temperature and water level should be adjusted.

(C) The temperature of the cross-linked pipeline: the higher the temperature, the faster the cross-linking reaction, but the temperature is limited, wet cross-linked by the vapor pressure limit, generally not more than 19600 kPa pressure. Dry cross-linking, the temperature is too high, the polymer will produce degradation and other side effects, so the cable outside the surface temperature is generally controlled at about 300 degrees. The length of the cross-linked pipe line is also a great impact on the line speed, the longer pipe length, line speed can be accelerated (of course, under other conditions permit) and line is short the the line speed is slow .

(D) other: cable cross-section, material formula and other factors will affect the line speed. Reasonable linear velocity determination is more complex, the appropriate line speed should be calculated on the basis of calculation and test , and then determine the degree of cross-linking, and then adjust the line speed to achieve the best line speed. This process can also be done with a computer.
