The difference between cable with armor and without armor
Author: Robby
The main differences between cables with and without armor are safety, price, mechanical properties, anti-interference performance and use environment.
Safety: Armored cables provide a higher degree of safety due to the additional metal protective layer, such as steel wire wrapping or cross-linked polyethylene insulation, which provides a higher degree of protection and reduces the impact of external factors such as physical damage and electrical hazards.
Price: Due to the additional protective layer and more complex manufacturing process, armored cables usually cost more than unarmored cables, with a market price approximately 15% higher.
Mechanical properties: Armored cables show better resistance when facing mechanical pressure and shear force, which can effectively reduce the breakage or deformation of cable conductor due to external force. This makes the armored cable more suitable in harsh environments or situations that require frequent movement.
Anti-interference performance: The armored cable impedes the invasion of electromagnetic wave through its metal layer, providing better anti-interference performance, especially more effective against high-frequency and low-frequency electromagnetic wave interference, so as to ensure the stability of transmission.
Use of the environment: armored cables are usually used in special environments such as submarine, underground or plateau because of their enhanced mechanical and anti-interference performance. While unarmored cables are more suitable for dry, fixed indoor environments.
In summary, the choice of armored or unarmored cables should be decided according to specific application requirements and environmental conditions.
