What are anti-interference cables?
The phenomenon of interference during information transmission causes signal attenuation from the transmitting device to the receiving device, leading to signal distortion, instability, and impacting the accuracy of the information exchange process. Therefore, to ensure a reliable signal transmission system, smooth device operation, and to mitigate interference, anti-interference cables have been developed to meet these requirements.
Interference when transmitting information causes the signal to be to be attenuated, flickering and unstable, affecting the accuracy of information exchange process. Therefore, to ensure a reliable signal transmission system, smooth device operation, and to mitigate interference, anti-interference cables have been developed to meet these requirements.
Anti-interference cables play a crucial role in transmitting signals within a circuit and establishing control systems in the industrial sector. They ensure signal transmission from the central hub to remote devices without dependency on electromagnetic waves.
These cables are favored products in various projects, especially in large-scale constructions such as buildings, industrial plants, and technical machinery. Anti-interference cables not only guarantee signal quality but also enhance transmission efficiency, ensuring the quality of devices and minimizing potential risks for users.
Structure of anti-inteference cables
Anti-interference cables are constructed with three main components: the conductive core, the insulating layer, and the protective outer layer.
Conductive core
This is the primary component of the anti-interference cable, made from flexible metal (usually aluminum or copper) that is easily bent. Depending on the specific requirements, users can choose cables with fewer or more cores.
Insulating sheath
The insulating layer plays a crucial role in the structure of the anti-interference cable as it is responsible for protecting users from electrical-related risks and minimizing the potential for unfortunate accidents. To enhance safety, the insulating sheath is typically made from insulating materials such as Polyethylene or PVC. Additionally, these sheaths are often reinforced with single or double mesh shields, made from aluminum or tin-plated copper, providing an extra layer of protection for users.
Protective shield
Constructed from Cross-Linked Polyethylene (XLPE) or PVC plastic, this component serves as a protective shield for the two inner layers. The protective shield is designed to withstand strong impacts and adapt to harsh weather conditions. This ensures that the cable can resist collisions, external forces, and environmental impacts during prolonged operation. Some basic types of protective shields include Steel Wire Armour, Steel Wire Braiding, Steel Tape Armour, Galvanised Steel Wire Armour, and Double Steel Tape Armour.
Applications of anti-inteference cables
Building systems
In building systems, the use of anti-interference cables helps to maintain stability and signal quality in security control systems, lighting systems, information systems, and other electronic devices. Within building environments, numerous sources can generate interference, such as electronic devices and lighting systems. Anti-interference cables help minimize the impact of these sources on electrical signals transmitted through the system.
Mechanical engineering industry
In the mechanical engineering industry, anti-interference cables play a crucial role in transmitting signals and data between devices and control systems, ensuring accuracy and stability in the manufacturing and operation of machinery. Additionally, the use of anti-interference cables helps to protect electronic devices and controls from the effects of electromagnetic interference. This not only extends the lifespan of the equipment but also reduces the risk of malfunctions and damage caused by signal interference.
Automation sector
In the field of automation, anti-interference cables are widely applied to transmit control signals and information between sensors, control devices, and automated systems. This plays a vital role in maintaining high performance throughout the entire system.
