NH-BV copper-core PVC-insulated fire-resistant wire
Fire‑resistant cables are designed to maintain operation for a specified period under flame‑exposure conditions, thereby preserving circuit integrity; this type of cable retains its ability to supply power for a certain duration in a fire. Fire‑resistant cables can continue to function—carrying current and transmitting signals—during a fire, regardless of whether they self‑extinguish. In contrast, flame‑retardant cables cease operation rapidly when exposed to fire, with their primary function being to resist ignition and prevent the spread of flames, achieving self‑extinction. Fire‑resistant cables can sustain normal operation for 180 minutes when subjected to a flame at 750–800°C.
Ordinary insulated wire—household electrical cable—is the most commonly used type. Taking a 100-square-meter new home as an example: 200 meters of 4‑square‑millimeter copper‑core BV wire, 400 meters of 2.5‑square‑millimeter wire, 300 meters of 1.5‑square‑millimeter wire, and 100 meters of 1.5‑square‑millimeter two‑color copper‑core BV wire. The above figures assume no suspended ceiling; if you install a ceiling, you’ll need slightly more 1.5‑square‑millimeter wire.
