Qiancheng Aluminum XLPE LSZH Low Voltage Power Cable adopts halogen-free raw materials. It delivers high smoke transmittance during combustion without toxic corrosive gas, facilitating personnel evacuation. It meets high-grade fire-safety specifications for rail transit, hospitals and so on, with abundant acceptance records of overseas public-construction projects as supporting evidence.
Compared with copper-core cables of the same specification, self-weight is reduced by approx. 30 %, bringing down costs of raw-material, sea transportation and manual laying. It shows remarkable advantages for long-distance municipal trunk-line projects. Different from inferior aluminum cables on market, this product uses brand-new high-purity aluminum rod, avoiding excessive resistance and overheating risks caused by recycled impure aluminum.
XLPE insulation permits long-term operating temperature of 90℃. It features aging-resistance, acid-alkali-resistance and moisture-resistance. It resists cracking and aging for long-term laying outdoors or in cable trenches, outperforming PVC-insulated cables and cutting later-stage maintenance-replacement expenses.
For each batch of Qiancheng Aluminum XLPE LSZH Low Voltage Power Cable, test archives including combustion test, voltage-withstand test and resistance test are kept for 5 years. Customer on-site sampling retest is supported. We own a CNAS-accredited laboratory; all tests are completed in-house without outsourcing.
Halogen-free and heavy-metal-free construction. Only a small amount of light smoke is generated in fire without highly-toxic corrosive gas, maintaining visibility for fire-scene evacuation and reducing risks of suffocation and poisoning. It is flame-retardant to restrain continuous flame spread along cables and prevent rapid fire escalation.
Stable resistivity of high-purity aluminum conductor with 20 ℃ DC resistance complying with standards. Temperature rise is controllable during long-time operation. Uniform-thickness XLPE insulation passes power-frequency voltage-withstand tests for all finished cables. Insulation performance remains stable under complex environments such as humid cable trenches and underground utility tunnels, lowering risks of electric leakage and short-circuit. Actual measurements from multiple overseas municipal projects show far-lower failure rate than non-standard cables.
Flexible and wear-resistant sheath resists damage from dragging and bending during construction to reduce electric-shock hazards. Raw materials contain no harmful halogen substances with no pungent odor for installation in enclosed spaces, ensuring long-term safe power-supply for densely-populated sites.
Low-voltage power distribution for metro tunnels, light-rail platforms and underground passages.
Power-distribution circuits for wards and emergency areas in hospitals and health-care centers.
Fire-safety and general power-distribution for exhibition centers, high-rise office buildings, schools and shopping malls.
Comprehensive utility tunnels, underground parking garages and civil air-defense projects.
Outdoor lightweight eco-friendly power-distribution trunk lines for new urban districts and industrial parks.
Minimum ambient laying temperature shall not be lower than 0 ℃. Pre-heating of cables is recommended for construction under low-temperature conditions to prevent sheath brittle cracking.
Minimum bending radius ≥ 15 times cable outer diameter. Keep away from sharp edges and corners to avoid scratching insulation layer.
Suitable for indoor cable-tray routing, outdoor overhead installation and cable-trench laying. Long-term water immersion is prohibited.
Special aluminum terminals must be adopted for aluminum-conductor connections, with matching fire-protection accessories for joints.
Keep wiring away from high-temperature heat sources as much as possible to extend cable service life.
Qiancheng is a large-scale physical cable manufacturer. Information about factory premises, production lines and testing laboratories is verifiable. We have undertaken numerous overseas infrastructure projects. Qiancheng Aluminum XLPE LSZH Low Voltage Power Cable supports length cutting and custom cable marking. Complete sets of Chinese-English test certificates are available to assist project acceptance and customs clearance.
A: This product meets high-grade fire-safety specifications for rail transit. We have acceptance cases of multiple overseas public-construction rail-transit projects. Complete test documents are provided and third-party retest is supported to facilitate smooth project acceptance.
A: Aluminum-core features lighter weight and lower costs for material, sea-freight and laying, suitable for long-distance trunk-lines. However its current-carrying capacity is inferior to copper-core. Copper-core variants are preferred for high-current short-distance loops.
A: Direct use of ordinary copper terminals is not recommended. Special aluminum terminals must be used for aluminum-conductor connections, and fire-protection accessories shall be installed at joints to avoid overheating failures caused by poor contact.
A: XLPE insulation is moisture-resistant and acid-alkali-resistant. All finished cables pass power-frequency voltage-withstand tests and deliver stable insulation performance under utility-tunnel conditions. Nevertheless, long-term water immersion shall be strictly forbidden; otherwise sheath aging will still be accelerated.
A: Laying ambient temperature shall not drop below 0 ℃. Pre-heat cables under low-temperature working conditions. Forcible dragging and bending are prohibited to prevent brittle cracking damage of sheath under low-temperature.
A: Keep wiring away from sharp edges of components to prevent scratching of sheath and insulation. Meanwhile keep cables away from high-temperature heat sources to extend service life.
