Screening

Screens are often used in instrumentation cables to prevent or reduce possible interference in cables that can be caused by the following reasons:

  • Cross-talk from adjacent pairs or triples;
  • Interference induced by external source such as electrical equipments, machinery, power line.

Screens can be:

Aluminium/polyester tape

with a tinned copper drain wire, the most popular construction

Copper/polyester tape

with a tinned copper drain wire, for a better screen effect

Bare copper braid

for electromagnetic interference or when the cable is subject to movements

Tinned copper braid

for electromagnetic interference in presence of corrosive atmosphere or high temperature
