在制造海底同轴电缆的过程中,采用多槽水的冷却系统来避免气泡的形成和增加聚乙烯绝缘与内导体之间的粘附力。在海底同轴电缆系统中,聚乙烯绝缘的介质特性标准很严格。在聚乙烯里少量水的不利影响也不可忽视。在电缆的制造过程中,突然冷却有利于减少在聚乙烯里水的含量.相反,逐渐冷却可以较好地避免气泡的形成。为了从这二种不相同的条件中找到一种最佳制造方法,用现有的试验数据用计算机来模似聚乙烯里水的扩散机理和起泡机理.
In the manufacture of subsea coaxial cables, a multi-tank cooling system was used to avoid bubble formation and increase the adhesion between the polyethylene insulation and the inner conductor. In submarine coaxial cable systems, polyethylene dielectric properties of the stringent standards. The negative impact of a small amount of water in polyethylene can not be ignored. In the cable manufacturing process, the sudden cooling is conducive to reducing the water content in the polyethylene.On the contrary, the gradual cooling can be better to avoid the formation of bubbles. In order to find an optimal manufacturing method from these two different conditions, the existing experimental data were used to simulate the diffusion mechanism and foaming mechanism of polyethylene in water.
