ZMS Cable and Accessories

Underground cables are an essential component of modern electrical systems, providing a safe and efficient way to transmit electrical power over long distances. Unlike overhead power lines, which are vulnerable to damage from storms and other natural disasters, underground cables are protected by being buried underground, making them a reliable and resilient option for transmitting electricity. There are several different types of underground cables , each designed for specific applications and environments.  Some Of The Most Common Types Of Underground Cables Include: 1. High voltage cables: These cables are used for transmitting electricity over long distances, typically at voltages of 66 kV or higher. High-voltage cables are often used in power transmission systems, connecting power plants to substations and other distribution points. 2. Low voltage cables: These cables are used for distributing electricity at lower voltages, typically between 600 and 1,000 volts. Low-voltage ca...

Ultra- high voltage transmission refers to the use of 500 kV-1000 kV voltage levels to transmit electrical energy. If the 220kV transmission index is taken as 100%, the relative investment per kilometer of UHV transmission, the relative cost of 100 kilometers per kilowatt-hour transmission, and the consumption of metal materials will be greatly reduced. In this way, the utilization rate of the line corridor has been significantly improved. In daily life, we can often see overhead UHV power transmission projects. However, now there is a question, have you ever thought about it: Why can't high-voltage wires be buried underground like urban underground cables?       The current underground cables generally have lower voltage levels. The transmission of high-voltage lines is often overhead, which is mainly due to cost and technical factors. First, the structure of underground cables is more complicated than that of overhead lines . The second is that underground cabl...
