Advantages:
Cost-effective: Aluminum conductors cost significantly less than copper conductors, making them suitable for long-distance, high-capacity power transmission projects.
Strong mechanical protection: Steel tape armor provides good resistance to compression and impact, suitable for direct burial or moderately complex environmental installation.
Stable electrical performance: Cross-linked polyethylene insulation offers good resistance to partial discharge, low dielectric loss, and high long-term operational reliability.
Wide environmental adaptability: Polyvinyl chloride sheath is resistant to moisture and corrosion, suitable for various scenarios such as outdoor, tunnel, and pipeline applications.
Convenient construction and maintenance: The armored structure enhances cable tensile strength, facilitating installation and future maintenance.

Application Scope:
Mainly used for aluminum conductor power transmission systems requiring certain mechanical protection in urban grids, industrial plants, substations, tunnels, cable trenches, and direct burial installations. Particularly suitable for long-distance power transmission environments that may be subject to external pressure, such as roads and farmland.

Special Notes:
Aluminum conductors require connection fittings and techniques; the armor layer increases cable rigidity—pay attention to the minimum bending radius during installation; steel tape armor provides radial crush protection and is unsuitable for vertical shafts with large drops or applications requiring high tensile strength; additional protective measures are recommended when direct burying.
