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.
Lightning Strike Analysis of 10kv Aerial Bundled Cable Lines and Lightning Protection Countermeasures
The reliability of power supply in the distribution network is a basic concept and an important index in production, application, and life. It not only affects the production of electricity for industrial enterprises and residents’ life but also affects the quality of electricity consumption and social benefits. With the rapid development of the distribution network, the power supply area is covered by trees, buildings under the line rows, typhoons, and many other factors shadowing making the reliability of the distribution network face new difficulties.
The Difference Between ABC Aerial Bundle Cable And BLX Cable
At present, the amount of domestic overhead cables is increasing, and various enterprises are producing and developing various overhead cables required by the market. In daily sales and production, some customers still propose to order BLX cables to replace overhead insulation. According to the survey of the market, some mainstream wire and cable manufacturers are no longer producing BLX cables. The following is a little idea of the differences between the two types of cables.
Detailed Differences Between High Voltage Direct Current (HVDC) and High Voltage Alternating Current (HVAC)
High Voltage Direct Current (HVDC) power transmission systems (also known as power highways or electric highways) use direct current (DC) to transmit power versus the more common alternating current (AC) systems. Most HVDC power transmission lines use voltages between 100 kV and 800 kV.
What Do You Mean By Shielded Cable? And What Is A Cable Shield Layer?
The shield on the shielded cable is the cable formed in the way of the transmission cable plus a shield against external electromagnetic interference. The so-called ‘cable shielding’ on the cable structure is also a measure to improve the distribution of electric fields. The cable conductor is made of multiple strands of wire stranded, it is easy to form an air gap between the insulation layer, and the conductor surface is not smooth, which will cause the electric field concentration. Then the following will give you detailed knowledge about shielded cables.
