Flame-retardant, fire-resistant plastic insulated wire
Flame-retardant and fire-resistant plastic insulated wires are dedicated to electrical wiring and power connection in fire-critical scenarios, widely used for emergency power supply, fire-fighting equipment circuits and key system wiring in high-standard construction and industrial projects.
Typical application scenarios include high-rise buildings, hospitals, subway stations, data centers, shopping malls and industrial fire-proof zones. Integrating flame retardancy, fire resistance and stable electrical performance, the wires ensure circuit continuity during fires, greatly improving building fire safety and emergency rescue capability.
Flame-retardant and fire-resistant plastic insulated wires adopt high-purity solid or stranded copper conductors with stable conductivity and superior bending flexibility. The core insulation is made of specially formulated fire-resistant and flame-retardant plastic materials, with uniform extrusion thickness and tight structural adhesion.
With a compact and lightweight integral structure, the wires adopt professional fire-resistant wrapping and flame-retardant extrusion technology. The optimized structure effectively inhibits flame spread and maintains structural integrity under high-temperature fire conditions. The finished products deliver excellent abrasion resistance, aging resistance and structural stability for long-term fixed laying.
These plastic insulated wires feature stable low conductor resistance and excellent insulation performance under rated operating voltage. They maintain consistent electrical parameters and low dielectric loss during long-term continuous power supply and frequent load fluctuations, ensuring reliable power and signal transmission.
Equipped with outstanding electrical aging resistance and dielectric stability, the wires can sustain continuous circuit conduction and insulation integrity in fire emergencies. They effectively avoid power outage and signal interruption caused by flame erosion and high temperature, ensuring operational safety of electrical systems under both normal and fire conditions.
The wires are designed, manufactured and tested in strict accordance with national standards GB/T 5023 and GB/T 19666 for flame-retardant and fire-resistant electric wires and cables.
They comply with IEC international flame retardant and fire resistance test standards, as well as RoHS environmental requirements, fully meeting high-standard fire safety specifications for civil and industrial electrical engineering.
