What are Screen Cables ?

Screen Cables manufacturers are the type of cable which consists of multiple conductors which help in conveying signal with low energy signature mainly used for monitoring and controlling electrical system, power control and other processes associated with it. Such cables which are used in applications apart from power transmission also carry out important functions which help in smooth functioning of the process industries. Screen Cables Also is microprocessor based or computerized is instrument system. These cables are basically designed without interruptions and interference from external sources.

Application of Screen Cables

Screen Cables find applications majorly in Control and Communication applications. These cables are mainly used in process industries where a lot of systems are involved. Screen Cables are involved in Process Control, Communication of analogue signals or digital signals and voice transmission signalling in Industrial and process control circuitry. These cables are mainly used in process industries such as Oil and Gas, Petrochemicals, Fertilizers, Cement, Paper, Steel, Aluminium, Power plants, etc. Screen Cables can face high amount of electromagnetic interference which can lead to inaccurate transfer of signals. To avoid such unwanted interference certain rules need to be followed so that these cables experience less effect due to EMI. Screen Cables need to be as far away from Power cables as possible. They can be laid in separate ways to avoid cross take. If it is not possible to keep distance between Power cables and Instrument cables, then both cables should be laid in such a way that they cross each other at right angles. Loops formed on instrument wiring can cause interference, hence should be avoided while installing the cables.   Screen Cables need to be provided with Shielding/ Screening over the cables to avoid external interferences. These cables, conductors /cores are twisted together to form a pair. Individual pairs are shielded with aluminium-mylar foil with annealed tinned copper as Drain wire. In case of multiple cables, another similar shielding / screening is provided over all the collective screened pairs to ensure better shielding. The function is to provide protection to the data that is being transferred through these cables from external electromagnetic as well as electrostatic interference. Loss of data due to EMI is an undesirable effect and can be avoided by using shielded / screened cables. Shielding inside the cable is capable of reflecting the energy of the cable as well as the pickup noise generated by the cable and conducted to the ground. Due to such characteristics EMI does not infiltrate the shielding and cannot reach the conductor in any case. There are two types of shielding / screening namely Aluminium Foil with Drain wire type and Copper wire braided type shielding / screening.
