Shielded Conductor

Definition - What does Shielded Conductor mean?

A Shielded Conductor is an object that has a cover to protect it from signal interference when transmitting data signals. A conductor can be made of braided strands of copper (or other metal, such as aluminum) with a non-braided spiral winding of copper tape, or a layer of conducting polymer being the insulator. Usually this shield is covered with a jacket and it acts as a Faraday cage to reduce electromagnetic radiation that may interfere with other devices.

Petropedia explains Shielded Conductor

Many cables such as power cables need to be shielded in order to protect them from interference of signals from the nearby cables or conductors. Shielding of conductors and cables is necessary so as to make the oil and gas industry communication system function without any electromagnetic radiations and electrical interference which may affect the data signals. Shielded conductors and cables have a cover to protect the data signal from electrical noise. The purpose of shielding conductors and cables is basically to act as an electromagnetic energy interceptor. In addition to blocking the interfering electrical waves, shielded conductors or cables also ensure that any potentially disruptive energy is disposed of through efficient and proper grounding.
