POLYCAB SIGNAL CABLES
ere are various kinds of cables available in the market and each differ in terms of function and performance. Thermocouple cables, solar cables, halogen cables, optical cables and other specialty cables are widely used for various significant purposes. However, there exists a less known kind of cable, which has significantly occupied a major place in the cable sovereignty; they are known as Instrumentation cables. At first look, instrumentation cables may seem similar to other thick sheathed cables. However, your assumption would prove wrong when you compare its appearance with its performance. Instrumentation cables are not basic cables. They transmit signals from one end to the other with absolutely no distortion. Made of 99.99% pure EC grade copper, the conductors of these cables are treated as per the industrial standards for superior conductivity, flexibility and elongation. These cables are insulated with high quality PVC, which is capable of handling external temperature above 85 degree Celsius. Unlike ordinary cables which have a single protective sheath, these cables have multiple protective barriers, that protect it from high temperatures. Formed by firmly twisting a bunch of cables together, these cables are enveloped with translucent non-hygroscopic polyester tape, also known as Mylar tape. The thickness of these tapes vary from 20 to 50 microns and are scientifically enclosed to protect the cables from moisture and exceeding temperature. These cables usually bear a copper-braided shield or are enclosed in a poly-aluminum tape. The inner sheath of these cables are made of PVC and its thickness varies depending upon the size of the cable. However, the minimum thickness of the inner sheath is about 0.3mm. Constructed with Galvanized Iron, the robust armour used in these cables protect it from technical and mechanical damage. Mostly used for industrial applications where power generation and distribution play a major role, Instrumentation cables are designed to cater to engineering and micro-processing segments. Polycab’s instrumentation cables are meticulously manufactured as per the international standards, and are best in terms of quality, durability and performance.
