电缆屏蔽有非金属屏蔽和金属屏蔽两种方法。选用哪一种屏蔽方法取决于电缆的品种，如电力电缆首要是为了屏蔽和均化电场，承载短路电流，而通讯电缆则要屏蔽电磁场，以消除线芯间和外部对电缆的搅扰。电力电缆的屏蔽一起具有非金属屏蔽和金属屏蔽方法，详细取决于电缆的电压等级和短路电流的巨细等，关于金属屏蔽有些还取决于以及金属资料的导电性、热功能、布局和加工方法等，通讯电缆则多为金属屏蔽。这里就电缆的屏蔽作用、结构和资料进行了简略分析。<strong><a href='http://www.zsdqjt.com' target='_blank'>安徽中盛集团</a></strong></p> <p> 实心的导体相对外表比拟润滑，电场的散布比拟均匀。绞合的导电线芯由所以有多根单线组成，线芯外表各点电场散布不均匀，单线半径的巨细和其外表场强的巨细成反比联系，这就发生多导丝效应。导体因加工发生的毛刺、粉屑，形成******放电，也需求导体屏蔽。电缆厂为了使导体外表的电场散布相对比拟均匀，只要绕包带屏蔽和挤出屏蔽层，才干均化电场消除这些效应。</p> <p> </p><div
