Low-smoke halogen-free 4×35mm2 fire-resistant cable
Fire-resistant cable
Fire-resistant cables are suitable for fire, and require wires and
cables to be able to continue to run for a certain period of time
when they are found again to provide protection for fire fighting
and reduce losses. It is widely used in high-rise buildings,
nuclear power plants, petroleum, chemical, mining, and propagation
where high fire safety conditions are required. It is an essential
cable for emergency power supplies, fire pumps, elevators, and
communication signal systems.

Fire-resistant and flame-retardant cables
There are important differences between fire-resistant cables and
flame-retardant cables, even though they have undergone various
fire resistance tests to obtain their respective classifications.
In short, the design of flame-retardant cables prevents the fire
from spreading to new areas. Fire-resistant or fire-resistant
cables are designed to maintain circuit integrity and continue to
work for a specified time under specified conditions. The
distinction between the two is crucial when it comes to maintaining
life safety or when critical circuits needed for the plant to be
shut down safely immediately.
