  Suitable for cable trays, conduits, and wall installations in factories and buildings. Its good flexibility allows it to adapt to narrow shafts, dense conduits, and multi-turn wiring layouts.

• 4.1 Stable Electrical Performance and Reliable Conductor

  The 8000 series aluminum alloy conductor solves common defects of pure aluminum cables such as easy creep, loose wiring, and poor connection stability. Even under long-term full load and frequent current changes, it maintains stable conductivity, preventing overheating at joints. Overall conductivity fully meets engineering design requirements, ensuring continuous and stable power supply.

• 4.2 Class A Fire Resistance and Environmental Performance

  Utilizing a full LSZH (Low Smoke Halogen-Free) material system, the cable does not produce toxic or corrosive gases when burning, and produces extremely low smoke. It effectively inhibits flame spread, controls fire transmission, and reduces property damage. The non-toxic and pollution-free materials comply with green building and environmental protection regulations, and will not pollute the soil or air during use and disposal.

• 4.3 Superior Mechanical Protection and Extended Service Life

  The galvanized steel tape armor forms a robust protective layer for the cable body, providing excellent resistance to pressure, impact, and friction, effectively preventing damage during construction and long-term operation. The rust-proofing treatment of the steel tape ensures stable protection even in humid environments, significantly extending service life and reducing the frequency of replacements.

• 4.4 All-Weather Adaptability and Anti-Aging Capability

  The specially designed outer sheath offers excellent resistance to ultraviolet radiation, ozone, and weathering, allowing for stable operation year-round under various climatic conditions, including high and low temperatures, strong sunlight, heavy rain, and humidity, making it suitable for projects in different climate zones.

• 4.5 Excellent Construction Performance and Efficiency

  Compared to copper armored cables, this product is lighter, reducing transportation and handling difficulties. Its optimized structural design provides excellent flexibility and bending performance, facilitating cabling in confined spaces and complex bends, effectively improving overall construction progress and saving labor costs.

• 4.6 Moisture Resistance and Resistance to Weak Chemical Corrosion

  The integrated sealed structure effectively prevents moisture penetration. It exhibits a certain degree of resistance to weak acids and alkalis in common soils, maintaining stable performance even in long-term damp underground and semi-outdoor environments.

• 4.7 Significant Overall Cost Advantage

  Under the premise of equivalent power transmission performance and safety standards, aluminum alloy materials significantly reduce raw material costs. Combined with low maintenance rates and long service life, this creates higher overall economic benefits for engineering projects.
  

• 5.1 Design and Model Selection Key Points
  • Based on the load current, transmission distance, and project design drawings, select appropriate conductor cross-sectional area and core count to meet actual power requirements.
  • For projects with extremely high fire protection standards or fully enclosed space projects, prioritize low-smoke halogen-free flame-retardant cables.
  • For areas with harsh geological conditions and frequent external pressure, confirm the integrity of the armor and overall mechanical strength before procurement.
• 5.2 On-site Construction and Laying Specifications
  • Construction Temperature: Cables must not be laid when the ambient temperature is below 0℃ to prevent brittle cracking of the insulation and sheath.
  • Bending Control: Never forcibly bend or twist the cable. Follow the specified minimum bending radius to protect the internal insulation structure.
  • Traction Operation: When pulling the cable, control the traction force evenly. Excessive tension can cause conductor deformation and armor displacement.
  • Direct burial requirements: Lay a layer of fine sand around the cable and cover it with protective bricks or stone slabs to isolate the cable from sharp objects.
  • Corrosive environment protection: Do not lay the cable in strong acid or alkali environments for extended periods. If corrosive media are present on site, a corrosion-resistant sheath must be installed.
  • Terminal connections: Use dedicated connectors compatible with aluminum alloy conductors and standardize crimping and sealing processes to ensure a secure connection.
• 5.3 Procurement, Storage, and Acceptance Precautions
  • Cables should be stored in a dry, ventilated, and cool warehouse, away from open flames, chemical reagents, and humid environments. Avoid prolonged open-air storage.
  • Upon receiving the goods, inspect the cable's appearance, outer diameter, insulation integrity, and the clarity of markings. Randomly check product certificates and test reports to ensure batch quality consistency.
