塑料能做导体吗? 什么是塑料导体?
塑料通常被认为具有非常差的导电性, 这就是为什么它们被用来制造电缆的绝缘护套. 然而, 科学家们发现，塑料导体可以通过将塑料与高浓度的丝状炭黑和焦化化合物混合制成. Plastic conductors are … 阅读更多
电线电缆导体预热时需要注意什么?
Wire and cable are used to transmit electrical (磁的) 活力. 线材产品的信息与电磁能量转换的实现. 广义上讲, wire and cable are also referred to as cable, and narrowly speaking, cable refers to insulated cable. It can be defined as a collection of the following parts: one or more insulated wire cores, and they may have their cladding, total protective layer, and outer sheath, the cable can also have additional conductors without insulation.
影响电线电缆产品绝缘电阻的因素
The insulation resistance of wire and cable products mainly measures the volume resistance of the cable insulation layer, 无法测量表面电阻, and more factors affect the value of cable insulation resistance. In practical application, there are four main factors on the insulation resistance coefficient.
