The Armored Shielded Control Cable (KVVP2-22 Series) is designed for transmitting control, monitoring, and protection signals. It is composed of copper conductors, PVC insulation, aluminum/copper tape shielding, steel tape armoring, and a PVC sheath. This structure provides excellent electromagnetic interference resistance and superior mechanical protection. It is suitable for fixed installations, underground applications, or environments with high mechanical stress, commonly used in industrial automation, energy, petrochemical, and transportation systems.

FAQ
Q: What is an Armored Shielded Cable?
A: An armored shielded cable is an electrical cable with a protective metal armor and a shielding layer to prevent mechanical damage and electromagnetic interference (EMI).
Q: Where is it commonly used?
A: It is used in industrial, commercial, and outdoor installations where mechanical protection and EMI resistance are required, such as control systems, instrumentation, and power distribution.
Q: What are the main construction features?
A: The cable typically has copper conductors, PVC or XLPE insulation, a metallic shield (copper tape or braid), and an outer armor (steel tape or wire).
Q: What are the benefits of using armored shielded cables?
A: They provide enhanced mechanical strength, protection against electromagnetic interference, and improved reliability in harsh environments.
Q: How to choose the right armored shielded cable?
A: Choose based on voltage rating, current capacity, environmental conditions (temperature, moisture, mechanical stress), and the level of EMI protection required.
