TELEFONIKA-Xz-TKMXpw-5x4x0

Telecommunication (T) local (M) cable (K) with twisted pairs (bundle), insulated with foam polyethylene with an outer layer of solid polyethylene (Xp), in a polyethylene sheath with a moisture barrier (Xz), filled with gel (w).

XzTKMXpw cables are designed for building local telecommunication networks (e.g., connecting subscribers to central offices) and creating communication networks in buildings (e.g., intercoms, sensors, alarms). They can be installed in cable ducts or directly buried in areas with low risk of mechanical damage. They cannot be used to power electrical devices.
