Fire Resistant Power Cable (1-4cores)
Fire resistant power cable can maintain the integrity of the circuit and continue to work for a period of time when exposed to fire. The cables are also know as CU/MICA/PVC/PVC 0.6/1KV or CU/MICA/XLPE/PVC 0.6/1KV to basic standard IEC60502-1 or BS 7846.
Layers of the mica tape is key materil to obtain the function of fire resistance in the cable. We we twist two layers of mica tape with 80% overlap rate whcih acheives a good performance of fire resistant.
