Coaxial Cables and Accessories<br />

A wide variety of coaxial cables, connectors,<br />

cable clamps, earthing kits, hoisting sockets<br />

and other accessories are available for main<br />

and branch feeders.<br />

All components are of broadband type.<br />

The minimum size of coaxial components<br />

is determined by the power handling<br />

requirements and environmental conditions.<br />

Oversized coaxial cables are often used to<br />

reduce cable losses.<br />

Coaxial cables<br />

The power handling capacity and the attenuation vary greatly with the frequency. The<br />

cables are semi-flexible due to the use of corrugated copper tubes as outer conductors.<br />

The inner conductor is centered using a polyethylene helix or polyethylene foam.<br />

Air dielectric cables are available in following dimensions:<br />

3/8″ 5/8″ 7/8″ 1 1/8″ 1 5/8″ 2 1/4″ 3″ 3 1/8″ 4″ 4 1/8″ 5″ 6 1/8″<br />

Air dielectric cables can be filled with dry air or nitrogen of 0.1 – 0.3 bar excess pressure.<br />

Foam dielectric cables are available in following dimensions:<br />

3/8″ 1/2″ 5/8″ 7/8″ 1 1/4″ 1 5/8″<br />

Special versions:<br />

Cables with fire retardent jacket or super-flexible types for narrow bends or improved<br />

power handling capacity are available on request.<br />

Connectors<br />

Coaxial connectors for semi-flexible cables or rigid lines and adaptors are available<br />

in following sizes:<br />

N 7-16 13-30 7/8″ 1 5/8″ 4 1/2″ 6 1/8″<br />
