Bare Aluminum Stranded Cable
- Conductor: Concentrically stranded multi-strand electrical aluminum wire
- Structure: Pure aluminum wire, no insulation layer
- Applications: Overhead transmission lines, substation busbars
Application
Power transmission: 35kV and below overhead transmission lines (LGJ/LJ); substation internal connection busbars; rural power grid renovation.
Power Distribution System: Main power distribution for buildings (aluminum alloy cables); power distribution for industrial parks; power collection systems for new energy power plants.
Special applications: Lighting power supply for long-span bridges; temporary power lines; cost-sensitive infrastructure projects.
Features/Parameters
Economic advantages: Low material cost: Aluminum is about 1/3 the price of copper; Easy transportation and installation: Lightweight, reducing support and labor costs; Significant advantages of large cross-section: The larger the cross-section, the more significant the cost savings.
Technical Characteristics: Corrosion Protection: Anodizing, oiling, or aluminum alloy composition optimization can be used; Connection Technology: Special aluminum terminals are required to prevent creep and electrochemical corrosion; Bending Performance: The bending radius of aluminum alloy cables is approximately 7-10 times the diameter, superior to traditional aluminum cables.
Environmental Protection and Safety: Halogen-free and low-smoke type: Suitable for densely populated areas; Flame retardant rating: Up to Class A/B/C flame retardant; Recycling value: Aluminum recycling rate is over 95%.
