低压电缆和高压电缆的区别。
The difference between low-voltage cables and high-voltage cables.
低压电缆与高压电缆的区别高压电缆从内到外分别为导体-内半导体层-绝缘层-外半导体层-金属铠装-护套层；低压电缆从内到外分别为导体-绝缘层-钢带-护套。许多低压电缆没有钢带。
The
difference between low-voltage cables and high-voltage cables is that
high-voltage cables are divided into conductor, inner semiconductor
layer, insulation layer, outer semiconductor layer, metal armor, and
sheath layer from inside to outside; Low voltage cables are divided into
conductors, insulation layers, steel strips, and sheaths from the
inside out. Many low-voltage cables do not have steel strips.
高压电缆和低压电缆的主要区别在于，高压电缆比低压电缆有更多的半导体层和屏蔽层。因此，高压电缆的绝缘层比低压电缆厚得多，结构凌乱，工艺要求高。半导体层中半导体层的主要效果是改
善电场效应。
The
main difference between high-voltage and low-voltage cables is that
high-voltage cables have more semiconductor layers and shielding layers
than low-voltage cables. Therefore, the insulation layer of high-voltage
cables is much thicker than that of low-voltage cables, with messy
structures and high process requirements. The main effect of the
semiconductor layer in the semiconductor layer is to improve the
electric field effect.
