drop-down GAS-INJECTED
SATELLITE COAXIAL |
 The
coaxial cables in this family are used especially for digital
transmission systems, now the best transmission medium for audio
and video television signals.
They
consist of:
• A central conductor consisting of a single red copper wire
or copperweld
• Insulation or dielectric material which isolates the central
conductor from the external conductor (shield).
The insulated part consists of polythene expanded by means of
what is commonly known as gas-injected technology, which improves
the mechanical, electrical and ageing characteristics of traditional
chemical expansion.
A tape-shield covering the entire surface, combined with a top
shield in red copper or tinned to varying coverage percentages,
with a double purpose: earthing of the conveyed signal and shielding
for isolating the signal from outside interference.
• A polyester tape designed to prevent plasticizers migrating
to the dielectric material.
• An external sheath in PVC or in halogen-free materials, with
low emission of
fumes and toxic gasses (LSOH). The sheath is usually coloured
according to the
RAL tables, but the colour can be customised.
• The customer's corporate logo can also be applied on request.
Development, final testing and production are guaranteed through
the use of the latest generation, highly updated instrumentation,
such as vector network analyser, absorbing clamp, impedance-meter,
on-line capacity measurement, FFT etc., all enabling on-going
monitoring and improvement of the product's quality level.
Our wide production range covers a multiplicity of needs: individual
systems, medium and large centralised systems, external tread-duty
laying, low losses for professional systems in addition to smaller
sized types for special uses. |
