Applications
FLAMEX® EN50264-3-1 4GKW FR flexible power cables maintain circuit integrity in case of fire (according to EN 50200 for 90 minutes) and are fire retardant, low smoke and halogen-free safisfying performance requirements of EN 45545-2-HL3.
On top of that, FLAMEX® cables withstand tough working conditions (oil, ozone, temperature variations, etc.).
