General Product Knowledge

1. What are the common types of special cables?

Our special cable portfolio includes:

  • High-Temperature Cables: Resistant to -60°C to 200°C+.

  • Flame-Retardant & LSZH Cables: Low smoke zero halogen, flame retardant grades V0/V1.

  • Shielded Cables: Anti-EMI/RFI for signal integrity.

  • Waterproof Cables: IP67/IP68 rated for submerged applications.

  • Explosion-Proof Cables: Spark and corrosion-resistant.

  • Drag Chain Cables: Highly flexible and abrasion-resistant for dynamic automation.

2. What are the core differences between special cables and ordinary cables?

  • Performance: Special cables withstand extreme environments (high heat, deep sea, strong EMI, radiation) and offer higher safety ratings. Ordinary cables only meet conventional electrical transmission needs.

  • Materials: We utilize advanced materials like fluoroplastics (PTFE/FEP), silicone rubber, and tinned copper, whereas ordinary cables rely on standard PVC and PE.

  • Applications: Specifically engineered for aerospace, marine, nuclear fusion, new energy, and heavy industry, rather than standard residential or commercial buildings.

3. What are the temperature ranges and applications for High-Temperature Cables?

  • Silicone Rubber: -60°C to 200°C.

  • Fluoroplastics: -200°C to 300°C.

  • Applications: Metallurgy, industrial kilns, aerospace, and new energy battery compartments.

4. What are the core advantages of Low Smoke Zero Halogen (LSZH) cables?

During a fire, LSZH cables release minimal smoke (transmittance ≥ 60%) and no toxic halogens (Cl⁻/Br⁻ content < 50mg/kg). This significantly reduces toxicity and corrosive gases, protecting both human life and sensitive electronic equipment. They are essential for subways, hospitals, data centers, and high-rise buildings.

5. How can I judge the quality of a special cable?

Look for four key indicators:

  1. Material Precision: Insulation layer thickness matches standards (±0.1mm); shielding coverage is ≥ 85%.

  2. Test Reports: Must pass extreme tests like temperature cycling (-40°C to 150°C for 1000 cycles) and maintain high insulation resistance (≥ 100MΩ·km).

  3. Appearance: Clear, durable surface printing (model/specs/certifications) with no bulges or scratches.

  4. Certifications: Compliance with global standards such as UL (USA), CE (EU), or CCC (China).
