NH YJV Combining Fire Safety Environmental Compliance Industrial Power Systems

Critical power failures during fires not only disrupt operations but also endanger lives and cause significant economic losses. NH-YJV enhanced fire-resistant power cables are designed to provide ultimate safety for builders, engineers, and facility managers worldwide. Featuring a high-density mica tape fire-resistant layer and upgraded XLPE insulation, this cable maintains stable power delivery for over 120 minutes at 850°C, ensuring the continued operation of life support systems, core industrial equipment, and emergency infrastructure during disasters. Unlike standard fire-resistant cables, NH-YJV cables combine long-term durability, environmental friendliness, and seamless compatibility with smart building systems, while simplifying the global certification process. This cable has obtained EU (CE/RoHS 2.0), North American (UL/cUL), Australian (SAA), and Middle East & North Africa (SASO) certifications, making it suitable for harsh, hot, humid, and corrosive environments worldwide, thus reducing your project costs and compliance hassles.

NH-YJV is a high-quality low-voltage (0.6/1kV) reinforced fire-resistant power cable designed for critical power transmission applications, especially suitable for situations where downtime consequences are severe. Its advanced multi-layer structure redefines reliability: Category 2 high-purity stranded copper conductors (low resistance, stable power supply), a high-density mica tape fire-resistant layer (reinforced with a ceramic coating, non-combustible and heat-insulating), an upgraded XLPE insulation layer (anti-aging, high-temperature resistant), non-combustible mineral fillers (ensuring core stability and moisture resistance), and a flame-retardant PVC outer sheath (scratch-resistant, corrosion-resistant). "NH" indicates N-class enhanced fire resistance (exceeding IEC 60331 standard), while "YJV" indicates XLPE insulated, PVC sheathed power cable. Its unique feature is that the ceramic-coated mica tape fire-resistant layer hardens into a protective shell during a fire, preventing heat penetration—superior performance to standard NH-YJV cables, eliminating the need for redundant spare cables.

• 120-minute enhanced fire resistance: Exceeding IEC 60331 and GB/T 19666 N-class standards, maintaining circuit integrity for over 120 minutes under an open flame at 850℃. Ensures uninterrupted power supply to life support systems (hospitals), core industrial machinery, and emergency pumps—compliant with EU EN 50305, US NFPA 110, and Australian AS/NZS 3013 standards, easily achieving global project compliance.
• 70-Year Service Life: The upgraded XLPE insulation layer incorporates anti-aging additives and a corrosion-resistant PVC sheath, ensuring a service life of up to 70 years (more than 20 years longer than standard cables). This reduces long-term replacement and maintenance costs, making it ideal for large infrastructure and long-cycle commercial projects.
• Green and Smart Project Compatibility: Compliant with RoHS 2.0 standards (free of any hazardous substances), meeting global environmental standards. Its low capacitance and low impedance make it compatible with building management systems (BMS) and smart power monitoring platforms, ideal for modern smart buildings and industrial automation projects in the EU and North America.
• Comprehensive Damage and Weather Resistance: The outer sheath is infused with scratch and rodent repellent agents, resisting mechanical damage, oil, UV radiation, and extreme temperatures (-35°C to 95°C). It can withstand the extreme cold of -35°C in Northern Europe, the extreme heat of 58°C in the Middle East, the monsoon climate of Southeast Asia, and the dry environment of the Australian outback without additional protection.
• Global multi-certification and cost savings: CE/RoHS 2.0 (EU), UL/cUL (North America 600V), SAA (Australia), SASO (Middle East and North Africa), and IEC 60502 (global). A single cable can meet the needs of multiple markets, avoiding redundant product development costs. Compared to rigid cables, flexible structures reduce installation labor by 35%; no additional fire-resistant casing is required, thus reducing total project costs by 22%.

Note: All specifications are in stock (fast shipping within 3 days). Bulk orders can be customized in terms of core count (up to 5+1 cores) and cross-sectional dimensions (1.5~240mm²), and all certifications are guaranteed.

NH-YJV cables are specifically customized to meet regionally critical power needs, covering high-value, compliance-critical scenarios globally:

• North American Market: Medical facility life support power, industrial manufacturing core machinery power, warehouse cold chain backup power, high-rise residential emergency systems (UL/cUL certified, compliant with NFPA 70/110 standards)
• Australia and New Zealand: Commercial complex backup power, mining area emergency power, coastal infrastructure power (SAA certified, withstands inland high temperatures and coastal salt spray)
• Middle East and North Africa Market: Oil and gas field emergency power, desert solar project backup power, commercial building mains power (SASO certified) Certified, heat-resistant, and dust storm-resistant)
• Global industrial applications: safety power circuits in chemical plants, core power supplies in food processing plants, emergency power supplies in water treatment plants, and power supplies for smart city infrastructure (fireproof, durable, and compatible with intelligent systems)

What is the difference between NH-YJV and NH-YJV22?

NH-YJV uses a flame-retardant PVC outer sheath, suitable for cable trays, wall shafts, and indoor installation; NH-YJV22 adds a steel strip armor layer, suitable for direct burial, underground, or harsh industrial environments (impact-resistant, rodent-proof). Both have a fire resistance time of 120 minutes; please select according to the installation environment.

Can NH-YJV be used in hazardous areas (e.g., Zone 2 in the oil and gas industry)?

Yes. Our NH-YJV is compatible with Zone 2 hazardous areas (non-flammable gas environments) when equipped with explosion-proof accessories. It complies with IECEx auxiliary power standards for hazardous areas, making it ideal for oil and gas fields in the Middle East, North Africa, and North America.

Does this cable comply with the latest EU RoHS 2.0 standard?

Fully compliant. All our NH-YJV cables comply with RoHS 2.0 (2011/65/EU) and are free of 10 restricted substances (such as lead and mercury). We provide official RoHS 2.0 test reports for all bulk orders to ensure product compliance with EU market access requirements.

How do you guarantee the quality of bulk orders?

We implement a five-step quality control process: raw material inspection (copper, cross-linked polyethylene, mica tape) → in-process testing (insulation thickness, fire-resistant layer wrapping) → finished product fire resistance testing → certification verification → pre-shipment sampling inspection. All bulk orders come with a complete quality inspection report.

Is the flexible version (NH-YJVR) suitable for frequent bending?

Yes. NH-YJVR uses Category 5 stranded copper conductors, capable of withstanding frequent bending (minimum bending radius ≥ 10 times the outer diameter) without damaging the fire retardant or insulation. It is ideal for confined spaces, machine connections, and temporary emergency power lines.

Can bulk orders be customized in length?

Yes. We offer custom cutting services (minimum length 100 meters per segment) to meet the specific needs of your project and avoid waste. Custom-length products retain all certifications and enjoy the same 70-year service life guarantee.
