JENUINcable is a Chinese wire and cable manufacturers with more than 20 years of experience in designing, manufacturing, and selling green environmental–protective wires and cables.we provide xlpe cable,pvc insulated cable,pvc sheathed cable,lszh cable and so on.

 

Fire resistant control cable , the cable refers as multiple cores Cu. The function of mica is to prevent burning when cables catching fire. The cable can maintain the integrity of the electric circuit and continue to work for a period of time when exposed to fire. The sheath is compound material LSFH low smoking free holagen which has little smoking and no toxic gas emission which reduces the damage to the people and equipment. These fire rated control cables we supplied are twisted two layers of mica tape with 80% overlap rate which achieves a good performance of fire resistance.

Application Of Fire Resistant Control Cable (2-4cores) 300-500V

 

The cables are designed for facilities where keeping and maintaining integrity of the electrical circuit is critical in power supply system.

 

The cables are widely used in underground tunnels, emergency lightings, fire alarm systems, control and power circuits, power stations, lifts, escalators, and high-rise buildings.
