INCOL Instrumentation Cables

INCOL Cables manufactures a wide variety of cables suitable for purpose instrumentation. In the projects related to Power Generation & Distribution, Chemicals & Fertilizers Industries and various other types of engineering industries, the process instrumentation plays a vital role in measurement, supervision and control of the process. Shield is provided to prevent harmful electrostatic interface.

There are three basic reasons for providing an electrostatic shield in a cable. The first, and most common, reason concerns the need to keep external electrical disturbances from affecting the signal in the cable. The second reason is to prevent the signal in the cable from being detectable at location other than all the cable ends. The third reason is the combination of the first two; it is the elimination of unwanted transfer of signals between circuits in the same cable, commonly called cross talk. The interfacing and connection of most data transmission equipment can be affected using either coaxial cable, screened or unscreened twisted pair cables.

For microcomputers, which use low speed data transmission over short distances, unscreened multicore or multipair cables can be used. For the inter connection of data processor, instruments, and microcomputers where signal interface is a consideration, cables are generally screened. Minicomputers require medium speed data transmission and for these, interfaces with screen twisted pair cables are suitable. When signal speeds are fairly low a braid screen is sufficient but for higher speeds a foiled screen or composite foil and braid screen is more suitable. A further refinement is to use individually screened pairs to minimize the effect of cross talk, thus making possible the transmission or data over long distances.

INCOL Cables with its meticulous efforts in maintaining quality, stringent in process control during manufacture and the knowledge of cable designing is proud to say that it is capable of supplying instrumentation cables meeting any Indian/International Standard or a specific requirement desired by project authority.
