- 1 General Details
- 2 PE, Polyethylene insulated and HFFR, Halogen Free sheathed cable is used as a telephone cable in indoor fixed installations, in dry or humid places. It is used in telephone exchange and subscriber distribution. Since halogen-free material is used in the cable structure (it does not take the flame late and does not transmit it, does not emit toxic gas after combustion and does not create black smoke that blocks vision), it is used in buildings where people are concentrated, especially in places that should not be affected by fire conditions.
