Product features:
Fire-resistant cables are designed to maintain operational integrity—specifically, the continuity of electrical circuits—for a certain period when exposed to flames. This type of wire retains its ability to supply power in fire conditions for an extended time. In the event of a fire, fire-resistant wires can continue functioning (delivering both electricity and signals), while whether they themselves continue burning is not part of the evaluation criteria. On the other hand, flame-retardant wires quickly cease functioning during a fire, as their primary purpose is to resist ignition and prevent the fire from spreading, ultimately allowing them to self-extinguish. Fire-resistant cables can sustain normal operation for up to 180 minutes when subjected to flames at temperatures ranging from 750°C to 800°C.
NH-BV fire-resistant cables are suitable for applications requiring the cable to maintain functionality for a certain period of time even in the event of a fire, under rated voltages of 450/750V and lower.
NH-BV is a type of cable that features an additional layer of fire-resistant mica tape wrapped around the core of the BV wire, making it ideal for wiring in critical facilities—such as key industrial plants and multi-purpose buildings that combine storage, office space, and residential areas—in areas where industrial growth and urban functional concentration are prominent.
