WHAT ARE SHIELD ELECTRICAL CABLES LIKE?

SHIELD ELECTRICAL CABLES

Shield electrical cables exist in different formats and configurations, shield means shielding and the most commonly found are aluminized polyester tape shields + drain wire, bare or tinned copper mesh and copper tape.

Electrical shield cables, their main purpose is to protect against noise, electromagnetic interference and EMI, which interfere with the transmission of data or signals and affect the functioning of a circuit, being very important to use in various applications so that the equipment works perfectly.

Shield electrical cables exist in instrumentation, control and power versions.

They can be manufactured with different thermoplastic or thermosetting materials, each with a specific purpose and application.

There are also electrical shield cables for use in mobile or fixed equipment, when used in constant movement the demands and durability of the components are extremely required and in this case it is interesting to count on our expertise in producing products for these conditions.

Shield electrical cables are found in voltages from 150 volts to 15000 volts.

Factors that contribute to electromagnetic interference in electrical shield cables:

The main factors are: Voltage, Frequency, Grounding, electronic components, Printed circuits and Decoupling.

There are three EMI paths between the source and the device to be influenced – the victim: Irradiation, conduction and induction.

Sources of EMI are classified as natural and non-natural – man-made. Natural sources can range from atmospheric noise, resulting from electrical discharges, to cosmic noise caused by explosions from the Sun.

Twisted pair electrical shield cables are made up of pairs of wires. The wires in a pair are wound in a spiral in order to, through the cancellation effect, reduce noise and maintain constant the electrical properties of the medium throughout its entire length. The cancellation effect reduces crosstalk between pairs of wires and reduces the level of electromagnetic and radio frequency interference.

We produce electrical shield cables resistant to weather, abrasion, flame, oil, grease, diesel, gasoline, Northern Lights, and also have UV protection and other resistances in order to meet the requirements of each project.

As the range of products is immense, it is advisable to consult our experts to recommend the best product for your project or application in order to obtain the best performance with the best cost and benefit.
