Product Description

Fire Resistant Power Cable is specially designed to maintain power transmission during a fire. It ensures the continuity of power supply to emergency circuits, such as fire pumps, alarms, lighting, ventilation systems, and emergency exits. The cable uses fire-resistant materials and special insulation to guarantee reliable operation under extreme heat or flame exposure.

Construction

- Conductor: Annealed copper, Class 1 or Class 2, according to IEC 60228.
- Insulation: Mica tape wrapped fire-resistant layer + XLPE or PVC insulation.
- Inner Sheath: PVC or LSZH (Low Smoke Zero Halogen) compound.
- Armour (optional): Steel Wire Armour (SWA) or Steel Tape Armour (STA).
- Outer Sheath: PVC or LSZH, available in red, orange, or customized colors.
- Voltage Grade: 0.6/1kV or as required.

NH-YJV	NH-YJLV	Cross-linked polyethylene insulated polyvinyl chloride sheathed fire-resistant power cable	To be laid indoors, in the tunnel, cable furrow, pipe or under soft soil. The cable can not bear mech- anical force from outside. Single core cable isn't permitted to be laid in the magnetic pipe.
NH-YJY	NH-YJLY	Cross-linked polyethylene insulated polyethylene sheathed fire-resistant power cable
NH-YJV22	NH-YJLV22	Cross-linked polyethylene insulated steel tape armored polyvinyl chloride sheathed fire-resistant power cable	To be laid underground (depth of burying: at least 0.7m above earth), the cable can bear certain mechanical force, but it can not beart great pulling force.
NH-YJV23	NH-YJLV23	Cross-linked polyethylene insulated steel tape armored polyethylene sheathed fire-resistant power cable
