6、绞合导体的同时采用紧压形式，使普通圆形变为半圆、扇形、瓦形和紧压的圆形。绝缘挤出塑料电缆采用挤包实心型绝缘层，塑料绝缘挤出的技术要求：偏心度：挤出的绝缘厚度的偏差值是体现挤出工艺水平的重要标志,大多数的产品结构尺寸及其偏差值在标准中均有明确的规定。光滑度：挤出的绝缘层表面要求光滑，不得出现表面粗糙、烧焦、杂质的不良质量问题．致密度：挤出绝缘层的横断面要致密结实、不准有肉眼可见的针孔，杜绝有气泡的存在。成缆对于多芯的电缆为了保证成型度、减小电缆的外形，一般都需要将其绞合为圆形。绞合的机理与导体绞制相仿，由于绞制节径较大，大多采用无退扭方式。成缆的技术要求：一是杜

7、绝异型绝缘线芯翻身而导致电缆的扭弯；二是防止绝缘层被划伤。大部分电缆伴随另外两个工序的：一是填充，保证成缆后电缆的圆整和稳定；一个是绑扎，保证缆芯不松散。existanymacroscopicpinholesorbubbles.StrandingMulti-corecablesaregenerallytwistedintocircular-sectionformtoensuretheircompactibilityandsmallersize.Themechanismoftwistingissimilartoconductorstranding.Sinceth
