Behind a grand communication project lie numerous unassuming cables, tirelessly carrying vast amounts of data. Have you ever wondered how coils of high-quality communication cables transform from raw materials into the "neural network" of modern society? Today, we will delve into a modern cable factory that complies with Chinese standards (GB) and industry norms—Henan Yellow River Cable Co., Ltd., to reveal the birth journey of communication cables from drawing to testing.

In everyday life, the terms "wire" and "cable" are often used interchangeably, but in reality, they represent different electrical products. Understanding their differences not only helps in selecting the right products but also ensures electrical safety. This article will provide a detailed analysis of the differences between wires and cables and their respective application scenarios.

In the wiring of data centers, hospitals, metro stations, high-rise buildings, and areas with high human traffic, Low Smoke Zero Halogen (LSZH) flame retardant cables have become the preferred choice. They can significantly reduce the release of toxic and corrosive smoke during a fire, buy valuable time for evacuation, and protect sensitive electrical equipment.

In harsh electrical installation environments—whether underground, under heavy pressure, or exposed to potential mechanical damage—ordinary cables appear fragile. In such scenarios, Armored Cables become an indispensable choice. However, not all armorings are the same. Among them, Steel Tape Armored (STA) and Steel Wire Armored (SWA) are the two main types, each with distinct performance and application scenarios.

In the world of cables, "fire safety" is of paramount importance. When we talk about fireproof cables, we often hear the terms "flame retardant" and "fire resistant." They sound similar, but they actually represent two fundamentally different functions and applications. Confusing them can not only increase project costs but, more critically, may create fatal safety hazards in the event of a fire.
Today, we'll precisely and accurately analyze the essential differences between flame retardant and fire resistant cables, based on their structure, materials, cost, IEC testing standards, and applications. This guide will help you make the most professional selection decisions.

In the world of power transmission, medium-voltage (MV) cables (typically 6kV to 35kV) play a crucial role. If you look closely, you'll find that MV cables have a very fixed design in terms of the number of cores: either single-core or three-core. You almost never see four-core or five-core MV cables, which is a significant difference from common low-voltage cables.
Behind this lies a set of rigorous electrical engineering principles. Why can't MV cables have more cores like low-voltage cables? And if we need a three-phase MV power supply with a grounding wire, what are the feasible alternatives?
