Cavicel fire resistant cables are designed according to international standards such as IEC 60331 IEC 60332 IEC 61034 and IEC 60754 for fire performance and safety
They maintain circuit integrity during fire conditions for a specified duration typically 90 to 120 minutes depending on cable type
Rated voltage commonly 300 500 V or 600 1000 V depending on application requirements
Conductors are made from high purity copper with solid or stranded construction for reliable conductivity
Insulation materials include fire resistant compounds such as mica tape and cross linked polymers to withstand high temperatures
Sheath materials are low smoke zero halogen to minimize toxic gas emission and smoke during fire
Operating temperature typically ranges from minus 20 up to 90 degrees Celsius under normal conditions
Fire performance includes flame retardant properties low smoke emission and zero halogen characteristics
Designed to resist mechanical stress moisture and chemical exposure in demanding environments
Used in safety critical circuits where continued operation during fire is essential
