Fire Resistant PVC Insulated Sheathed Power Cable

In the fixed laying scene of construction and industrial projects, it is very important to select a fire-resistant cable that meets the national standard and has high cost performance. Yilan Cable as a trusted supplier and factory, the production of NHVV Fire Resistant PVC Insulated Sheathed Power Cable strictly comply with GB/T 19216 standards, its signature orange/red sheath easy to identify, while ensuring the integrity of the circuit in case of fire, to provide you with significantly better economy than crosslinked polyethylene (XLPE) fire resistant cable.

Guard critical circuits

Yilan Cable NHVV fire-resistant power cable in the emergency moment of fire, to ensure that the fire system, emergency lighting and alarm lines of power flow, is to prevent the expansion of the disaster, to ensure the safety of evacuation lifeline. Common cables fuse in case of fire, while critical circuits must be held in flames. Yilan Cable's NHVV fire-resistant cable, designed specifically for such core scenarios, is the "power bridge" that remains indestructible under extreme conditions.

Why does it work so stably in flames?

The fire resistance secret of NHVV cable stems from its unique and reliable structural design:

1. Refractory Core-Mica Layer: On the outside of the conductor, we tightly wrap multiple layers of special synthetic mica tape. Cloud belt is a natural inorganic mineral, in the 750-800℃ flame direct burning, will not burn, but will be ceramic, forming a strong insulating skeleton, to ensure that the Fire Resistant PVC Insulated Sheathed Power Cable in up to 90 minutes or more time, to maintain the integrity of the line and continuous energization, fully meet GB/T 19216 and IEC 60331 standards.

2. Economical construction-PVC insulation and sheath: PVC is used for insulation layer and signature orange red sheath. This material provides good electrical insulation and mechanical protection at the same time, making its cost significantly lower than that of XLPE insulated NHYJV and other fire resistant cables, providing a cost-effective option for the project to achieve critical safety performance.

3. Clear identification: standard orange-red or red sheath, which can be quickly visually identified during laying and maintenance, clearly distinguished from ordinary power lines, in line with safety specifications.

Model comparison

Key Performance and Selection Guide Rated Voltage: 0.6/1kV

Temperature Range:

Long-term allowable working temperature: 70°C (limited by PVC material characteristics)

Maximum temperature in case of short circuit: ≤ 160°C (maximum duration 5 seconds)

Application area

1. Fire compulsory power supply system: fire pump, smoke fan, fire elevator dedicated distribution lines.

2. Emergency safety system: emergency lighting, evacuation instructions, fire alarm system power and signal lines.

3. Critical infrastructure: Building trunk power distribution, fixed-laid power mains in factories and tunnels that require fire resistance.
