BRIMSON CABLES PVT.LTD. manufactures the widest range of shielded cables designed for control, power data & instrument circuits. When a particular installation is prone to interference from either internal or external sourced, some from of shielding in the cable is necessary. Even if one installs the most accurate and reliable instruments to monitor and control the system will be as strong or as weak as the cable interconnecting them.

In shielded cables, ideally a coverage of around 85% is desired when providing braid shielding but it is often seen that the coverage is hardly in the range of 50% to 60% which leaves the cable exposed to all kinds of interferences. Moreover only an aluminium foil or braid shield on its own may not be effective enough to eliminate or reducehe interference problems, hence the need for Dual Screened Cable-wherein both an aluminium foil having 100% coverage (with minimum 25% overlap) in conjunction with shield is provided. Dual Screened is far more effective in the most demanding environments than ordinary screened cables.

These cables can also be termed as instrumentation cables, since they are used for process temperature measurment. The construction is similar to paried instrumentation cable but the conductor material is different. Thermocouples are used in processes to sence temperature and is connected to the pyrometer for indication and control. The thermocouple and pyrometers are electrically connected by the thermocouple extension/compensating cables. The conductors used for these cables are required to have similar thermoelectric (emf) properties as that of the thermocouple used or sensing the temperature. The cables are manufacturing as perIS : 8784, ANSI-MC 96.1, BS : 1843 ENI, DIn : 43714 : 43-323, JISC : 1610-1981 and customers specification.
