In this section, we focus on cable technology, product applications, and industry knowledge, carefully crafting a series of easy-to-understand and practical content, to provide readers with authoritative technical support and comprehensive industry interpretation.
Five Minutes to Teach You to Distinguish The Types and Application Scenarios of Submarine Cables
The types of submarine cables can be briefly divided into four aspects.
1. From the structure, is mainly divided into three-core submarine cables and single-core submarine cables. Low- and medium-voltage lines use mostly three-core submarine cable, and high-voltage lines use mostly single-core submarine cable.
The Web’s Most Detailed Thermocouple Wire Faqs
In order to better facilitate engineers to quickly grasp some of the expertise of thermocouples. I have collected the thermocouple 15 difficult questions about thermocouples, the details are as follows.
Common Thermocouple Types and Characteristics
There are several key types of thermocouple wire graduation numbers, such as S, R, B, N, K, E, J, T, etc. Among them, S, R, and B belong to precious metal thermocouples, and N, K, E, J, and T belong to cheap metal thermocouples.
What Is The Special Difference Between Ordinary Cables And Flexible Cables?
Since RVV and RVVP have a certain flexibility, they are often used as drag chain cables. However, compared with TRVV drag chain cables, they can only be called ordinary cables. Highly flexible cables have excellent flexibility, not only good bending and stretch resistance, but also have a shielding function, which is incomparable to ordinary flexible cables.

ADSS Fiber Optic Cable And High-Voltage Transmission Line With The Tower Erection Operation Problems
ADSS fiber optic cable is currently the most commonly used fiber optic cable for power communication, which is installed on high voltage transmission lines. Due to the strong electric field around the high-voltage transmission line, ADSS fiber optic cable, which is exposed to a strong electric field for a long time, is easily damaged by electric corrosion.
What Is FTTH Fiber Optic Cable? What Kind Of Structural Features Does It Have?
I. Preface
With the development of optical communication networks and the deepening of fiber-optic access, FTTH network construction is growing exponentially. At present, China Telecom and China Netcom have clearly indicated that they will invest heavily in the large-scale commercialization of FTTH. From this series of circumstances, the focus of fiber optic communication network construction will shift to FTTH in the next few years. The new generation of all-optical networks requires fiber optic cable as an optical signal transmission medium to provide wider working bandwidth, higher transmission rate, and longer transmission distance. It should also have a long service life and be easy to install and maintain.
Design Principle Of ADSS Fiber Optic Cable
In recent years, there are two main types of fiber optic cables laid in the power system, ADSS, and OPGW. Among them, ADSS fiber optic cable is welcomed by users for its lightweight, easy construction, and can make full use of the existing tower system, etc. It is developing faster. ZMS Cable Company is committed to leading the market in fiber optic cable technology and has conducted a lot of experiments to verify the design and production of fiber optic cable.
Defective Glass Insulators for Overhead Lines and Countermeasures
Due to its many advantages, glass insulators occupy 1/3 of the current line insulator usage. for the O&M department, glass insulators have the following advantages.
