Cable decription
1.1What is FR Cable
The typical structure of refractory cable is the cable with an additional refractory layer between conductor and insulation. This structure enables the cable to withstand 750 C, 90 minutes of fire resistance test.
1.2 Benefits of FR Cable
In fire accidents, fire-resistant cables can operate normally in a certain period of time.
While maintaining the integrity of power lines and the normal operation of safety equipment, fire-proof cables have won valuable time for personnel evacuation.
