5. Material Properties & Advantages:

• Economical: Cost-effective solution for low voltage power distribution.

• Durability: PVC insulation and sheath provide good resistance to moisture, abrasion, chemicals, and weathering.

• Flexibility: Easier handling and installation compared to some alternatives.

• Flame Retardant: Standard PVC properties (Specific fire performance ratings depend on formulation - check manufacturer specs).

• Reliability: Proven technology for stable power transmission.

6. Application Scenarios:

• Fixed Installations: Indoors, Outdoors, Underground (where mechanical damage is not expected), in concrete, in water.

• Power Distribution Networks: Low voltage mains and submains in residential, commercial, and industrial buildings.

• Infrastructure: Lighting circuits, HVAC systems, motor control circuits, machine tools, power distribution panels.

• Suitable Environments: Building sites, construction projects, cable ducts, conduits, cable trays (subject to support requirements).

7. Engineering Selection Data (NYY-J & NYY-O):

(Note: re = Solid Circular, rm = Stranded Circular, sm = Stranded Sector-shaped. Weights are approximate. Full specification sheet required for all available sizes and configurations.)

8. Installation Notes:

• Suitable for direct burial, installation in ducts, conduits, or on cable trays.

• Adhere strictly to minimum bending radii during installation to prevent damage.

• Ensure correct core identification for safe and compliant electrical connections.

• Installation should be performed in accordance with local regulations and electrical codes (e.g., IEC 60364, national wiring rules).
