More Fire Resistance When It Matters Most

Standard fire-resistant cables are designed to maintain circuit integrity for a limited duration under fire conditions. However, under prolonged exposure to high temperatures or severe fire scenarios, performance may gradually degrade.

Our Enhanced fire cable is engineered with an improved fire barrier structure. It incorporates multiple layers of mica tape with increased total thickness compared to standard fire-resistant constructions. This reinforced insulation system forms a more robust thermal protection layer, helping to delay heat transfer and maintain circuit integrity for a longer duration under continuous flame exposure. Critical systems such as fire pumps, emergency lighting, and safety control circuits can continue operating during fire conditions.

Strong Fire Performance with Stable Electrical Characteristics

In addition to fire resistance, electrical stability under normal operating conditions is fully maintained. The conductor is made of high-purity oxygen-free copper, providing excellent conductivity and improved resistance to oxidation at elevated temperatures.

The outer jacket uses flame-retardant materials designed to limit flame propagation along the cable route. Both armored and unarmored versions are available. The armored structure includes a double steel tape layer, providing additional mechanical protection for underground or outdoor installations.

The rated voltage options include 300/500V and 0.6/1kV, covering a wide range of control and power distribution applications.

Tested to International Fire Safety Standards

Our Enhanced fire cable is manufactured in accordance with IEC 60331 and GB/T 19216 standards. Production lines are equipped with online monitoring systems to ensure precise control of mica tape wrapping tension and layering consistency.

The product is certified to CE and RoHS requirements. Common models such as NH-YJV, NH-YJV22, NH-DJYPVP, and NH-KVV are available from stock. For export projects, complete fire test reports and customs documentation are provided. Moisture-resistant and impact-resistant packaging is used for long-distance transportation.

Frequently Asked Questions

Q: What is the difference between enhanced fire cable and standard fire cable?

A: The main difference lies in the fire-resistant layer structure. The Enhanced fire cable uses multiple layers of mica tape with increased overall thickness compared to standard fire-resistant cables. This creates a more effective thermal insulation barrier, slowing heat penetration and extending the duration of circuit integrity under fire conditions. In general terms, standard fire cables are designed for basic fire endurance, while enhanced fire cables are designed for extended and more stable performance under severe fire exposure.

Q: Do you accept third-party inspection?

A: Yes. We fully support third-party inspection by organizations such as SGS or BV. Inspection can cover dimensions, appearance, electrical performance, and fire resistance testing. All production records and testing equipment are made available during inspection. Shipment is released only after approval, ensuring full compliance with required standards and project specifications.
