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 />
