Mineral insulated Fire resistance cable
This type of cable is made up of single and multi-cores 600/1000V cables Service Temperature 90°C Emergency Overload Temperature 125°C Short-Circuit Temperature 250°C
The design, construction and testing are compliant with international standard IEC60502 and testing standard BS6387,with standing temperatures of 950~1000 °C for 90 minutes, which means they are capable of remaining in working order despite the most extreme fire conditions. Hence they are known as FIRE RESISTANT cables.
— Flame Retardant
— High Operating Temperatures
— LSOH Halogen-free
— Great Mechanical Strength
— Competitive Installed Cost
— Public Places
