Product features:
Fire-resistant cables are designed to maintain operation for a specified duration under flame combustion conditions, ensuring the integrity of the electrical circuit. This type of cable can provide power supply for a certain period of time when exposed to flames. In the event of a fire, fire-resistant cables can continue to function (transmitting current and signals); whether they themselves continue to burn is not part of the evaluation criteria. By contrast, flame-retardant cables quickly cease functioning when a fire occurs; their primary function is to be difficult to ignite and self-extinguishing, preventing the spread of fire. Fire-resistant cables can maintain normal operation for 180 minutes when exposed to flames at temperatures ranging from 750 to 800°C.
NH-BV fire-resistant cables are suitable for applications requiring the cable to maintain operational continuity for a certain period of time even in the event of a fire, with rated voltages of 450/750V and below.
NH-BV cables feature an additional layer of fire-resistant mica tape wrapped around the core of the BV cable, making them suitable for wiring in critical facilities within industrial systems and urban areas where functions are highly concentrated—such as multi-purpose buildings that integrate warehousing, office space, and residential units.
