Q What is the core difference between special cables and ordinary cables?
A
Performance: Specialized cables possess unique properties such as resistance to extreme environments (high temperature, corrosion, strong electromagnetic fields, nuclear fusion), as well as high safety standards (flame retardancy, low toxicity). Standard cables only meet conventional electrical transmission requirements.
Materials: Special cables use special materials such as fluoroplastics, silicone rubber, and tin-plated copper; ordinary cables are mostly made of PVC and polyethylene.
Application: Specialized cables are used in harsh environments such as industry, new energy, aerospace, underwater, seabed, wind power, and nuclear fusion; ordinary cables are only suitable for conventional settings like construction and household use.
Q What are the common types of special cables?
A
Common types include: high-temperature cables (resistant to -60°C to 200°C+), flame-retardant cables (low-smoke halogen-free, flame-retardant rating V0/V1), shielded cables (EMI/RFI protection), waterproof cables (IP67/IP68), explosion-proof cables (anti-spark/corrosion-resistant), drag chain cables (bend-resistant/wear-resistant), low-smoke halogen-free cables (low toxicity and smoke), and fusion reactor cables.
