Description
Technical Parameters
Keeps power flowing during a fire
 

In a fire situation, critical systems must continue operating. Fire pumps require power. Smoke exhaust systems require power. Emergency lighting must remain active.

Our Fire resistant power cable is designed specifically for these life-safety applications. Multiple layers of mica tape are applied around the conductors. Mica is a naturally fire-resistant mineral that does not melt or burn, withstanding temperatures up to 800°C.

When exposed to fire, the outer sheath burns away, but the mica tape forms a stable ceramic-like insulating layer. This structure maintains conductor separation and preserves circuit integrity.

This cable is available in two voltage ratings:

  • 300/500V
  • 0.6/1kV

This allows it to cover different power distribution and load requirements.

The conductor is high-purity oxygen-free copper, providing low resistance, stable conductivity, and reduced heat generation under load.

The outer jacket is flame-retardant PVC, which helps prevent flame propagation during normal operation.

The cable complies with IEC 60331 fire resistance standards and is capable of maintaining circuit integrity for at least 90 minutes at 750°C–800°C.

Tested under real fire conditions
 

We manufacture this cable in accordance with GB/T 19216 and IEC 60331 standards.

Our production line is equipped with online monitoring systems that track mica tape wrapping tension and overlap in real time, ensuring consistent fire-resistant performance.

Batch sampling and fire resistance testing are performed for every production lot.

Common models such as NH-YJV, NH-YJV22, and NH-KVV are available in stock.

For export projects, we provide complete fire test reports and customs documentation. Moisture-proof and impact-resistant packaging is used for long-distance transportation.

Frequently Asked Questions

 

Q: How long can this cable keep working during a fire?

A: The cable is tested according to IEC 60331. It can maintain circuit integrity for at least 90 minutes under flame temperatures of 750°C to 800°C. Actual performance may vary depending on installation conditions and fire environment. Each production batch is strictly tested to ensure compliance.

Q: Do you accept third-party inspection?

A: Yes. We fully support inspections from agencies such as SGS, BV, and other international inspection bodies. They can verify appearance, dimensions, electrical performance, and fire resistance testing.
We prepare all test records and production documentation in advance and cooperate throughout the inspection process. Shipment is released only after approval.
