LTC JF MT SWA

LTC JF MT SWA – underwater cable. Loose tube cable with armoring of galvanized steel wires for excellent resistance against crush, impact and tensile forces and heavily protected against water ingress, by means of cable jelly filling, swellable tapes and aluminium tape. This cable is suitable to be installed in freshwater for a water-depth of max. 50m. Installation: in sewer systems, water pressurized tunnels, lake and river crossings.
