Symmetric high-frequency cables / switchboard cables

Cables for telephone switches and switchboard back panels

For the transmission of high-frequency signals in telecommunications equipment such as telephone switches and switchboard back panels, we provide symmetric high-frequency cables and switchboard cables for transmission frequencies up to 32 MHz. These possess outstanding mechanical properties and are applicable for fix and mobile use. With a flame retardant and non corrosive cable jacket (FRNC), they are suitable for use with both indoor and outdoor applications. Due to small outer diameters and their high flexibility, our high-frequency and switchboard cables can be installed with low bending radii.

Our cables feature excellent electromagnetic shielding and a uniform foaming of the dielectric. One of our specialities is our unique skin-foam-skin extrusion.

We also provides RF-switchboard cables in pre-assembled versions.
