NH-KVV 0.6/1kV Low Voltage Uninterrupted Signal for Fire Safety & Automation

When fire or severe weather strikes, critical control circuits must not fail – this is why NH-KVV fire-resistant control cables are a transformative solution for builders and engineers worldwide. Featuring a special mica tape fire-resistant layer, it maintains uninterrupted control signals for over 90 minutes at 800°C, ensuring perfect operation of fire safety systems, industrial automation control panels, and emergency control systems in times of crisis. Unlike ordinary control cables, it combines fire resistance, low signal loss, and robust durability, requiring no additional fire-resistant casing, making it a cost-effective solution. With EU CE/RoHS certification, North American UL/cUL certification, Middle East SASO certification, and IEC 60228 global certification, NH-KVV cables are perfectly suited for projects in various high-temperature, humid, cold, or corrosive environments—making them your ideal one-stop choice for fire-resistant control cables.

NH-KVV is a professional low-voltage (0.6/1kV) fire-resistant control cable designed specifically for critical control signal transmission, effectively preventing serious risks caused by signal interruption. Its multi-layered structure ensures dual performance: Category 2 stranded copper conductors achieve low-impedance signal transmission; a mica tape fire-resistant wrapping layer (core fire-resistant layer); a PVC insulation layer ensures signal stability; tightly stranded core wires filled with flame-retardant material; and a flame-retardant PVC outer sheath provides all-around protection. Product markings "NH" (fire resistant) and "KVV" (PVC insulated sheathed control cable) make them ideal for control circuits that balance daily reliability with fire emergency capabilities—eliminating the need for separate backup cables, thus reducing project complexity and cost.

• 90-Minute Fire-Resistant Signal Continuity: Passes IEC 60331 and GB/T 19666 N-level fire resistance tests, maintaining circuit integrity for over 90 minutes under an open flame at 800°C. Ensures uninterrupted fire alarm, sprinkler control, and emergency lighting signals—compliant with global fire safety standards (EU EN 50200, US NFPA 70), making it an essential choice for fire-sensitive projects worldwide.
• Precise Low-Loss Signal Transmission: Stranded copper conductors and uniform PVC insulation minimize signal attenuation, perfectly suited for industrial PLC control, building management systems (BMS), and fire linkage control. Critical for high-precision production in EU automotive plants and North American manufacturing facilities.
• Globally certified, easy acceptance: CE/RoHS (EU), UL/cUL (North America, 600V compliant), SASO (Middle East), IEC 60228 (globally recognized). All orders come with complete test reports to help you pass local acceptance smoothly, no matter where your project is located.
• Harsh climate adaptability, globally applicable: The flame-retardant PVC sheath is corrosion-resistant, oil-resistant, and moisture-resistant, and can be used in extreme temperatures from -25°C to 70°C. No additional protection is required in the humid coastal areas of Southeast Asia, the hot climate of the Middle East, the cold winters of Northern Europe, and the dusty environments of EU industrial plants.
• Economical and easy to install: The flexible structure allows it to bend freely in confined spaces (control cabinets, wall shafts, machine gaps) without special tools, saving 20% ​​on labor costs compared to rigid control cables. No additional fireproof casing is required, reducing the total project budget by 15%.

Note: The above commonly used specifications are in stock and can be shipped quickly in 3-5 days; bulk orders can be customized with different core counts (37-61) and cross-sections (6-10mm²).

NH-KVV cables can be customized to meet the specific needs of regional projects, covering high-value critical control scenarios globally:

• EU Market: Hospital fire alarm control loops, automotive production line automation control, commercial shopping mall fire linkage systems, subway station emergency control circuits (compliant with CE/RoHS standards, meeting stringent EU fire safety regulations)
• North American Market: Factory PLC control systems, data center cooling unit control, residential community fire sprinkler control, warehouse emergency lighting control (UL/cUL certified, compliant with NFPA 70 electrical specifications)
• Middle East Market: Oil and gas field auxiliary control panels, desert infrastructure automation systems, commercial building fire safety control (heat and corrosion resistant, SASO certified)
• Southeast Asian Market: Coastal high-rise building fire control loops, power plant auxiliary system control, tropical factory automated production lines (moisture and salt spray resistant, compliant with IEC standards)
• Global Industrial Scenarios: Chemical plant safety control loops, food processing production line automation, water treatment plant monitoring and control (fire safety) (low signal loss, high versatility)

• What is the difference between NH-KVV and NH-KVVR cables?

  NH-KVV is a rigid control cable, suitable for fixed installations (e.g., building shafts, control cabinets); NH-KVVR is a flexible cable, suitable for applications requiring frequent bending (e.g., machine connections). Both have the same fire resistance; please choose according to your installation needs.

• Can NH-KVV operate in high-temperature industrial areas (above 70°C)?

  Its long-term operating temperature is 70°C; for areas with sustained temperatures between 70-90°C, we recommend our high-temperature enhanced version (NH-KVV-HT), which features a heat-resistant sheath, is fully certified, and compatible with your existing systems.

• Do you offer regional certification for my local project?

  Yes. We offer targeted certifications: EU CE/RoHS, North American UL/cUL, GCC (GCC) SASO, Australian SAA, and more. Please inform us of your project location, and we will match you with the appropriate certified products.

• Are common specifications in stock? How long will it take to receive samples?

  All specifications in the common specifications list are in stock. Free samples (5-8 meters) can be shipped within 3 days, and delivery to your local port worldwide takes 7-12 days.

• What are the installation precautions for NH-KVV?

  Avoid pulling or twisting the cable during installation; the minimum bending radius should be ≥ 10 times the cable diameter; except in fire emergencies, do not expose the cable to open flames for extended periods.

• What is the warranty period for bulk orders of NH-KVV?

  We offer a 3-year warranty for bulk orders. If quality problems arise due to non-human factors, we will provide free replacement or a full refund.
