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.

Description

Product Description

Product Features:

　　　Fire‑resistant cables are designed to maintain operation for a specified period under flame‑exposure conditions, thereby preserving circuit integrity; they retain the ability to supply power for a certain duration in a fire. In the event of a fire, fire‑resistant cables can continue to function—carrying current and transmitting signals—while their own self‑extinguishing properties are not subject to evaluation. Flame‑retardant cables, by contrast, cease operation rapidly when exposed to fire; their primary functions are to resist ignition and to self‑extinguish without spreading the flame. Fire‑resistant cables can sustain normal operation for 180 minutes when subjected to a flame at 750–800°C.

NH-BV fire-resistant cables are suitable for applications where, under fire conditions, the cable must continue to operate for a specified period of time, with a rated voltage of 450/750 V or lower.

NH‑BV is a type of cable that features an additional layer of fire‑resistant mica tape wrapped around the conductor of a BV‑type cable. It is used for wiring in critical industrial facilities, as well as in major multi‑purpose buildings that integrate storage, office space, and residential areas, particularly in urban settings where functions are highly concentrated.
