影响电子线束寿命的要素有以下几点：
     1.原资料质量差：直接关系到线束的生活品质的原资料，电缆线束是正常的铜产值，但并不是所有的厂商将由线材加工行业遵守规则，一些线束厂家为了降低成本，从而使更多的赢利，铜包钢，镀锌铁或铜包层电缆束制造，运用这种资料质量的线束的造出来可想而知，更不用说寿命。
    2.服务环境: 线束的服务环境也是影响线束运用寿命的一个要素。 户外运用的吊具肯定不如室内运用的吊具长，如户外广告灯箱所运用的吊具长期暴露，雨水会大大缩短吊具的运用寿命。
    3.不合法运用：不同厚度的电子线束能够接受不同的电流。假如在大电流下运用细线束，因为不能接受太大的电流，会产生热量，导致线束或设备焚毁，严峻乃至起火。因而，在运用线束时，要看它是否能接受相应的电流。
