NH-KYJY/Refractory Crosslinked Polyethylene Insulated Polyethylene Sheath Control Cable
NH-KYJY
NH-KYJY fire-resistant control cables are the core products that ensure the safe operation of key circuits. "NH" represents the refractory characteristic. The cable uses a double-layer gold mica belt wrapped around the copper core. Under a high temperature flame of 750-1000℃, it can still maintain stable power supply for more than 180 minutes, ensuring the continuous operation of the control system in extreme situations such as fires. The cable conductor is made of high-purity oxygen-free copper, which has excellent conductivity, low resistance and small transmission loss. The cross-linked polyethylene insulating layer has excellent electrical insulation and high temperature resistance. It can have a long-term working temperature of up to 90℃, which is resistant to aging and cracking. The outer polyethylene sheath is wear-resistant, moisture-proof and corrosion-resistant, with high mechanical strength, flexible and easy to lay. Suitable for AC/DC or pulse circuits below 450/750V and below, it is widely used in high-rise buildings, subways, hospitals and other places with strict fire prevention requirements, and provides reliable connection guarantees for important control systems such as fire alarms and emergency lighting.

NH-KYJY Refractory Crosslinked Polyethylene Insulated Polyethylene Sheath Control Cable: Superior Performance in Extreme Environments
NH-KYJY, a"Refractory Crosslinked Polyethylene (XLPE) Insulated Polyethylene (PE) Sheath Control Cable,"is a cutting-edge solution designed for critical control systems that must operate reliably in high-temperature and fire-prone environments. Engineered with refractory materials and advanced insulation, this cable combines durability, flexibility, and fire resistance to meet the toughest industrial and commercial safety standards.
Core Design and Refractory Innovation
NH-KYJY features a stranded copper core for flexible conductivity, ensuring stable signal transmission in complex control systems. The crosslinked polyethylene (XLPE) insulation offers exceptional thermal stability, withstanding continuous temperatures up to 90°C and short-term exposure to 1000°C during fires—far exceeding traditional PVC-insulated cables. The outer polyethylene (PE) sheath provides additional protection against moisture, abrasion, and chemical corrosion, while maintaining flexibility for easy installation. This design ensures the cable retains electrical integrity during emergencies, making it ideal for fire alarms, emergency shutdown systems, and industrial control panels.
Applications in High-Risk Sectors
- Industrial Fire Safety: Used in refineries, power plants, and manufacturing facilities to wire critical control circuits, such as boiler safety systems and fire suppression mechanisms.
- Commercial Infrastructure: Installed in high-rise buildings, hospitals, and data centers for emergency lighting, elevator controls, and fire command center wiring.
- Marine and Offshore: Resists saltwater corrosion and extreme heat in engine rooms and offshore platforms, ensuring reliable operation in maritime environments.
- Tunnel and Transportation: Suitable for subway tunnels and airport terminals, where its low-smoke, halogen-free properties comply with strict safety regulations for enclosed spaces.
Performance and Compliance
- Fire Resistance: Meets international standards like BS 6387 and IEC 60331, surviving rigorous fire tests (950°C for 3 hours with water and impact) while maintaining circuit continuity.
- Electrical Reliability: Stranded copper cores ensure low resistance and high conductivity for precise control signals (up to 450/750V).
- Environmental Durability: XLPE and PE materials resist UV rays, oil, and chemicals, extending the cable’s lifespan in harsh outdoor and industrial settings.
Why NH-KYJY Outperforms Traditional Cables
- Refractory Excellence: XLPE insulation provides superior heat resistance compared to PVC, making it ideal for prolonged exposure to high temperatures.
- Flexibility Without Compromise: Despite its fire-resistant properties, NH-KYJY remains flexible, allowing easy routing through tight conduits or around machinery.
- Sustainability: Halogen-free construction reduces toxic emissions during fires, aligning with eco-friendly and safety-first project requirements.
Conclusion
NH-KYJY control cables are a testament to innovative engineering, delivering unmatched refractory performance without sacrificing flexibility or reliability. Whether protecting industrial operations, commercial buildings, or transportation networks, this cable ensures critical systems remain functional when safety is non-negotiable. For projects that demand"fireproof"resilience and"future-proof"design, NH-KYJY sets the standard—proving that advanced materials and meticulous craftsmanship can transform control wiring into a cornerstone of emergency preparedness.
