Fire Resistant PVC Insulated Sheathed STA Power Cable

In projects where budgets are limited but safety standards cannot be compromised, it is critical to select a professional China cable supplier and factory. Yilan Cable's high-quality NHVV22 Fire Resistant PVC Insulated Sheathed STA Power Cable achieves fire resistance through conductor wrapped special mica tape, supplemented by double-layer steel tape armor to resist external damage, significantly lower than the cost of halogen-free low smoke cable, providing you with excellent fire resistance in line with national standards and IEC standards, ensuring continuous operation of key equipment in emergency situations.

NHVV22 VS ordinary cable

When fires break out, power outages often mean fire systems are down and escape routes plunge into darkness. Common cables fail quickly in flames, and continuous power supply to critical equipment (such as fire pumps, smoke exhaust fans, emergency lighting) is the last line of defense to save lives and property.Fire Resistant PVC Insulated Sheathed STA Power Cable not only supplies power during normal conditions, but also "extends" life and critical equipment for more than 90 minutes under extreme fire conditions.

Core advantages

1. Good fire resistance: the conductor is tightly wrapped with multi-layer special mica tape.Mica is a natural inorganic mineral, in the 750-800℃ flame burning, can quickly ceramic, forming a strong insulating protective layer, to ensure that the line in the raging fire can continue to supply power for more than 90 minutes, fully meet GB/T 19666 and IEC 60331 standards and other requirements, for fire disaster relief for valuable time.

2. Double-layer armor: the cable adopts double-layer steel tape gap armor. This layer of steel armor provides excellent compression resistance, impact resistance and rodent bite resistance, especially suitable for direct burial, pipe penetration or mechanical damage prone industrial environment, effectively prevent cable damage caused by construction excavation, geological settlement or accidental impact, and ensure the physical safety of the line.

3. Cost-effective: NHVV22 cable is designed to cost significantly less than halogen-free, low-smoke fire-resistant cables at the same fire resistance and protection levels. For industrial buildings, tunnels and other fixed installation scenarios with relatively loose requirements for flue gas toxicity, it is one of the best economic choices to meet the specification requirements and optimize the total investment of the project.

4. Stable electrical performance: rated voltage 0.6/1kV, insulation resistance ≥3.67 MΩ·km, long-term allowable working temperature 70°C.PVC sheath provides good oil resistance, acid and alkali corrosion resistance, and adapts to a variety of complex industrial environments.

Installation and laying

High quality Fire Resistant PVC Insulated Sheathed STA Power Cable has a certain rigidity, and it is recommended that the minimum bending radius is ≥12 times the cable outer diameter. When laying directly, fine sand or soft soil protective layer shall be laid above and below the cable to avoid direct damage of armor layer by sharp stones. Both ends of armor layer must be reliably grounded.

Selection and service

As a source manufacturer, we offer flexible customization from conductor cross-section (e.g. 4mm² to 240mm²), core count (1-5 cores) to packaging. We can provide ex-factory inspection reports with the goods, and support third-party organizations sampling. We offer a 3-year warranty and professional technical laying guidance.
