Fiber Optic Hybrid Cables First and Second Generation Comparison

Optical hybrid cable is a hybrid form of cable that integrates fiber optics and conductive copper wires, which can solve the problems of data transmission and device power supply at the same time with a single cable. In larger campus networks, fiber optic hybrid cables are mainly used to complete the connection between the switch阅读更多

高压电缆故障的原因有哪些?

这是高压电缆最常见的组合.

High-voltage cables usually refer to transmission lines that carry voltages above 10kV. According to GB/T 2900.50-2008, definition 2.1, high voltage usually does not include 1000V. Overhead Line Method High-voltage transmission cables are usually transmitted underground by cables with insulation in cities, and often transmitted in the field using overhead lines carried by pylons.   金属丝 … 阅读更多

对电线绝缘及其应用的类型的最完整的解释

什么是绝缘?

电缆绝缘是任何电缆的重要组成部分. 它由覆盖电线的非导电材料制成. 也称为电绝缘.
绝缘的目的是将电流与电缆的其余部分分开, 将其保持在电线内并防止其进入周围环境.
同时, 隔热材料可保护电线免受安装环境中的恶劣条件的影响,并确保其正确的操作.
可以用不同的材料制成绝缘, 取决于电线的目标应用.
但总的来说, 塑料, 橡皮, 荧光聚合物是电线绝缘的最常见类型.
