I believe everyone has a general understanding of flexible YTTW fire-resistant cable. However, your understanding of flexible fire-resistant cable likely focuses on its performance and a general description. You may not yet understand its internal structure. Below, we will introduce the internal structure of YTTW flexible fire-resistant cable.
1. Overview
YTTW flexible fire-resistant cable, also known as copper-sheathed corrugated inorganic insulated cable, is a new type of fire-resistant cable that improves upon the shortcomings of mineral insulated cable. It overcomes the limited production lengths of mineral insulated cable and avoids the problem of intermediate joints during installation and laying. It also offers advantages such as moisture-resistant insulation and easy installation. With the continued promotion of this product, its excellent performance has been increasingly recognized by customers and is now widely used in basic industrial and civil construction.
II. Applications of Flexible Fireproof Cables
1. Powering equipment and lighting systems in important buildings or buildings with large crowds of people;
2. Powering critical flammable and explosive environments, such as those in the petrochemical industry and coal mining;
3. Powering critical military, defense, aviation, and satellite base equipment;
4. Powering critical equipment in power plants and nuclear power plants;
5. Locations with high ambient temperatures, such as steel mills, smelters, and glass factories;
6. Powering firefighting equipment and fire-resistant elevators in various buildings;
7. Powering power equipment in locations requiring exceptional cleanliness and hygiene, such as hospitals and food factories.
III. Structure of Flexible Fire-Resistant Cable
Internal Structure of YTTW Flexible Fire-Resistant Cable
1. Cable Conductor: Made of multiple twisted copper wires with excellent bending properties.
2. Insulation: Made of a high-temperature-resistant, non-flammable inorganic insulation material.
3. Copper Sheath: Made of copper material, specially processed to provide excellent bending properties and used as PE cable.
4. Filler: Made of a non-toxic, harmless, non-polluting, non-corrosive, flame-retardant, and safe inorganic filler.
5. Outer Sheath: Made of a low-smoke, non-toxic plastic with excellent corrosion resistance.
