Special wire and cable is usually much stronger in anti-interference ability than ordinary wire and cable. This difference is mainly reflected in the following aspects:1. Design and structureSpecial wire and cable usually adopts special design and materials to improve its anti-interference ability. The main design features include:Shielding layer: Special cables usually have additional shielding layers, such as copper braided mesh, aluminum foil, etc., which can effectively block electromagnetic interference (EMI) and radio frequency interference (RFI).Double or multi-layer shielding: In order to enhance the anti-interference performance, some special cables adopt double or multi-layer shielding design, which is more effective than the single-layer shielding of ordinary cables.High-quality insulation materials: Special cables use high-quality insulation materials, which not only have good insulation properties, but also effectively reduce the impact of external interference on signals.2. Materials and manufacturing processesConductor materials: Special cables may use high-purity conductor materials, such as oxygen-free copper or silver, which have lower resistance and better conductivity.Insulation materials: High-frequency, high-temperature, chemically resistant insulation materials (such as fluoroplastics, polytetrafluoroethylene, etc.) are used in special cables to enhance the anti-interference ability of cables in harsh environments.3. Application environmentSpecial wire and cable are often used in environments that are sensitive to interference, such as:Military and aerospace: Equipment in these fields has extremely high requirements for signal stability, so cables with strong anti-interference performance are required.Industrial automation: In industrial environments, there are many sources of electromagnetic interference, and special cables can ensure the stable operation of equipment.Medical equipment: Medical equipment has high requirements for signal accuracy, so cables with high anti-interference performance are also used.4. Comparison with ordinary wire and cableOrdinary wire and cable are usually simple in design, focusing on basic conductivity and insulation protection, and have weak anti-interference ability. Ordinary cables may only be equipped with basic single-layer insulation and shielding, which is difficult to cope with strong electromagnetic interference environments.5. Cost and priceBecause special cables use higher-end materials and complex manufacturing processes, their cost and price are usually higher than ordinary cables. This is one of the reasons why they are used in specific application scenarios.In short, special wire and cable is significantly better than ordinary cables in terms of anti-interference ability, especially in complex and demanding application environments, its strong anti-interference ability can ensure the normal operation of the equipment and the stable transmission of signals.
