CONSTRUCTION

1. N2XH Cable Structure

• Conductor: Typically composed of high-purity copper or aluminum, annealed for flexibility and low resistance.

• Insulation: Cross-linked polyethylene (XLPE) insulation provides excellent thermal resistance (up to 90°C) and dielectric strength.

• Shielding: A concentric copper tape or braid shield minimizes electromagnetic interference (EMI).

• Jacket: Thermoplastic or thermosetting material (e.g., PVC or LSZH) offers abrasion resistance and flame retardancy.

2. N2XH-J Cable Structure

• Conductor: Similar to NXXH but may include additional stranding for enhanced flexibility.

• Insulation: XLPE with higher dielectric breakdown voltage, suitable for industrial high-voltage applications.

• Armor: Steel-wire or tape armor protects against mechanical stress (e.g., rodent damage or crushing).

• Outer Jacket: Reinforced with fiberglass or aramid yarn for tensile strength in harsh environments.

3. N2XH-O Cable Structure

• Conductor: Copper with silver plating for improved conductivity in corrosive environments.

• Insulation: Silicone rubber insulation for extreme temperature resilience (-60°C to +200°C).

• Shielding: Dual-layer shielding (aluminum foil + copper braid) for superior EMI protection.

• Jacket: Fluoropolymer (e.g., PTFE) resists UV, chemicals, and moisture, ideal for outdoor installations.
