Cable and fiber optic cable line integrity combustion testing machine

With continuous advancements in technology, cables and fiber optic cables play a vital role in modern society, providing critical infrastructure for communication, energy transmission, and other applications. However, under extreme conditions, such as during a fire, the integrity of these cable lines becomes a crucial safety factor.

Application

This device is used for testing cables and optical fibers that are required to maintain circuit integrity when subjected to a flame with a temperature of at least 750°C (with controlled heat output) during a separate fire test.
