How to measure the temperature of cable trays
Optical fiber sensors can detect abnormal heating of power lines in cable trays and high voltage power cables in cable tunnels. They enable blind-spot–free monitoring—24 hours a day 365 days a year—in out-of-reach places and spaces that are too narrow for people to enter. It explains typical causes of fire, outlines technical and organisational solutions, and provides recommendations for installation. Environmental Factors: How hot or humid the air is, and how well air moves around, also affects how well cables cool down. In hot, damp, and still air, cables struggle to cool. When cables get too hot, several bad things can happen: Faster Aging: Heat makes the insulation inside cables wear out. The best, most economical way to avoid serious problems from overheat conditions or damaging fires in cable trays and electronic facilities is a temperature monitoring system using the Xco Continuous Thermocouple, FTLD ™. The Senkox TDS-CT Temperature Monitoring System provides an ideal solution for the temperature monitoring of cable trays.
