Fire-resistant electrical cables are insulated with polyvinyl chloride (polyethylene) and the conductors are wrapped with fire-resistant muscovite mica tape.Fire-resistant mica tape boasts excellent fire resistance, acid and alkali resistance, and anti-corona and anti-radiation properties, with good flexibility and tensile strength. It is suitable for key areas such as public venues and large convention halls. Electrical wires and cables prevent combustion or do not burn when exposed to open flame.
