Aluminum-conductor cables reduce self-weight by about 30 %, lowering material, cross-border logistics and installation labor costs, which helps control infrastructure budgets for long-distance municipal projects. Unlike ordinary aluminum cables on the market with simplified fire-resistant structures, this product is equipped with a complete double-layer mica fire-resistant layer, balancing cost-performance and fire-protection requirements.
Adopting XLPE insulation, it features higher temperature resistance, acid-alkali resistance and anti-ageing performance, delivering longer service life under outdoor and cable-trench conditions and reducing later-stage maintenance and replacement costs.
Tested by third-party laboratories: it can maintain continuous power supply for 90 minutes under 750 ℃ open-flame environment, and the outer sheath extinguishes rapidly upon flame removal. Validated by numerous overseas fire-renovation projects, it achieves a higher pass-through rate for fire-supervision acceptance.
Aluminum XLPE FR Low Voltage Power Cable has built-in double-layer mica fire-resistant structure. Under high-temperature conditions, the mica layer sinters to form a heat-insulating barrier. It sustains power supply for 90 minutes under 750 ℃ open flame to guarantee normal operation of emergency lighting, fire-fighting pumps and alarm devices. The flame-retardant outer sheath achieves self-extinguishing upon flame removal and inhibits fire spread along cable trays. Its eco-friendly flame-retardant formulation produces low-smoke low-toxic combustion fumes to reduce suffocation risks in fire scenarios and complies with fire-safety codes for public buildings.
High-purity aluminum conductors deliver stable resistivity. 20 ℃ DC resistance is kept within standard range with controllable temperature rise during long-term operation. XLPE insulation features uniform thickness without eccentricity. All finished cables pass power-frequency withstand-voltage and insulation-resistance tests and maintain stable insulation performance under complex conditions such as humid cable trenches and outdoor overhead laying, minimizing electric-leakage and short-circuit faults. Long-term field tests in multiple overseas municipal projects show significantly lower circuit-failure rate compared with non-standard aluminum-conductor cables.
The cable outer sheath is wear-resistant and extrusion-resistant, not easy to damage during construction pulling and bending, lowering on-site electric-shock hazards. Raw materials contain no heavy-metal hazardous substances and produce no highly corrosive flue gas in fire. Durable fire-retardant and fire-resistant performance prevents spontaneous combustion caused by overload or ageing. It is suitable for high-occupancy venues including schools, hospitals and residential areas, with proven long-term safe-operation records from multiple implemented projects.
1.Minimum ambient laying temperature ≥ 0 ℃. It is recommended to pre-warm cables indoors before construction under low-temperature conditions to prevent sheath embrittlement and cracking.
2.Applicable scenarios: indoor fire-protection cable trays, outdoor overhead laying, cable trenches, mild direct burial in soil.
3.Long-term underwater immersion laying is prohibited.
4.Special aluminum terminals must be adopted for aluminum-conductor connections. Joints shall be sealed with matching fire-resistant heat-shrinkable sleeves to guarantee flame-retardant and fire-resistant performance at joints.
5.Integrated fire-proof structure. No additional on-site wrapping with fire-proof coil materials is required, effectively shortening construction periods.
A：It is about 30 % lighter than copper-conductor cables of the same specification, cutting material, logistics and installation labor costs. It retains complete double-layer mica fire-resistant layers, unlike some aluminum cables on the market with simplified fire-resistant structures, balancing cost and fire-safety standards.
A: Third-party tests verify that it can maintain continuous power supply for 90 minutes under 750 ℃ open-flame environment to keep fire-fighting pumps, emergency lighting and other equipment running. The sheath self-extinguishes rapidly after flame removal, facilitating project fire-safety acceptance.
A: XLPE insulation features high temperature resistance, acid-alkali resistance and anti-ageing performance. It adapts to outdoor and cable-trench environments with longer service life and reduces investment for later-stage maintenance and cable replacement.
A: DC resistance of high-purity aluminum conductors complies with standards with controllable temperature rise. XLPE insulation has uniform thickness. Finished cables pass power-frequency withstand-voltage and insulation-resistance tests. Insulation performance remains stable under humid and overhead laying conditions, lowering risks of electric leakage and short-circuit.
A: Laying ambient temperature should not be lower than 0 ℃. Pre-heating is recommended for low-temperature construction. It supports tray laying, overhead installation, cable-trench laying and mild direct burial. Long-term underwater immersion is not allowed.
A: Special aluminum terminals must be selected for connections. Joints shall be sealed with fire-resistant heat-shrinkable sleeves to guarantee fire-retardant and fire-resistant performance at joints. Copper terminals shall not be used directly in substitution.
A: The cable adopts integrated fire-proof structure. No extra on-site fire-proof coil wrapping is needed, simplifying working procedures and shortening overall construction duration.
A: The sheath is wear-resistant and extrusion-resistant and not easy to damage during pulling and bending. Raw materials contain no heavy-metals and produce low-smoke low-toxic combustion fumes. It resists spontaneous combustion caused by overload and ageing, making it suitable for venues such as hospitals, schools and residential areas.
