Selection and Application of Armored Cables
Armored cables, as a type of wire and cable with excellent mechanical protection and protection capabilities, play a crucial role in power transmission and signal transmission due to their characteristics and application fields. Below, the editor will explore in detail the characteristics of armored cables and their wide applications in various fields.
1、 Characteristics of armored cables
Armored cables are mainly composed of conductors, insulation layers, metal sheaths (armor layers), and other accessories, which together endow armored cables with a series of unique characteristics:
1. High mechanical strength: The armor layer is usually made of metal materials such as steel strips and steel wires, which give the cable strong tensile, compressive, and wear-resistant capabilities. This design enables armored cables to operate stably for a long time in complex or harsh environments.
2. Good protective performance: The armor layer, as the outer layer of the cable, can effectively isolate the external environment from erosion of the internal conductors of the cable, such as compression resistance, seismic resistance, rain resistance, corrosion resistance, etc. In addition, armored cables also have good sealing properties, which can prevent the penetration of water vapor and other harmful substances.
3. Excellent insulation performance: Insulation layer materials such as polyvinyl chloride (PVC), polyethylene (PE), etc. have good insulation performance and can withstand a certain degree of high and low voltage environments, effectively avoiding short circuits and fires.
4. Strong electromagnetic shielding capability: The armor layer not only provides physical protection, but also effectively shields external electromagnetic interference, ensuring stable transmission of power signals and communication data.
5. Excellent temperature resistance: Armored cables can withstand high temperature environments, ensuring that power and signal transmission under high temperature conditions are not affected.
6. Easy installation and maintenance: Armored cables are easy to bend and install, reducing construction difficulty. Meanwhile, its sturdy casing also reduces maintenance costs.
2、 Application Fields
1. Power system: In the power system, armored cables are commonly used to transmit high-voltage currents, ensuring the stability and reliability of power supply. Armored cables play an important role in power plants, substations, and transmission and distribution networks.
2. Communication network: In communication networks, armored cables are used to transmit high-speed data and signals, with good anti-interference capabilities to ensure communication quality. Especially in areas where fiber optics cannot reach or where costs are high, armored cables have become the preferred solution.
3. Petrochemical industry: Equipment and facilities in industries such as petroleum, chemical, and metallurgy often need to withstand extreme conditions such as high temperature and high pressure. Armored cables, with their excellent corrosion resistance and high temperature resistance, work stably in these harsh environments, ensuring reliable transmission of power and signals.
4. Construction industry: Armored cables are commonly used in electrical wiring of buildings for power supply, lighting, and other systems, especially in environments such as underground passages and high-rise buildings that require additional protection and durability.
5. Transportation infrastructure: In the construction of transportation infrastructure such as railways, subways, and highways, armored cables are commonly used in the construction of electrical power supply systems to ensure the normal operation and safety of transportation systems.
6. Industrial field: In the industrial production process, armored cables are commonly used to connect various equipment and machines, such as motors, conveyor belts, etc., to ensure the stability and safety of power transmission.
7. Civil electronic products: Armored cables have also penetrated into various aspects of daily life, such as mobile phones, air conditioners, televisions, and other electronic products, ensuring the stability and safety of their power transmission.
