What Is a Fire-Resistant Cable? An Overview of Fire Resistance, Cable Structures, and Material Selection
A fire-resistant cable (also referred to as a fire-rated cable) is not a cable that simply “does not burn.” It is designed to maintain circuit integrity under specified fire, time, and mechanical conditions. These cables are commonly used in critical systems that need to remain operational during...Read more -
What Is OPGW? An Overview of Its Structure, Materials, and Manufacturing Process
For many people, the first impression of OPGW is simply “optical fiber inside a metal structure” installed on a transmission line. In reality, there is much more to it. OPGW (Optical Ground Wire) is a specialized cable that combines the functions of an overhead ground wire with optical fiber comm...Read more -
How to Choose the Right Cable Sheathing Material? A Guide to PE, PVC, LSZH and TPU
Cable sheathing is an important protective layer for power cables and optical cables.
