Why Our Instrumentation Cables?

• Made using cutting-edge technology
• Customized solutions available
• Economically priced

• The connection and interfacing of most data transmission equipment can be easily affected using either screened or unscrewed twisted pair cables or coaxial cable.
• For microcomputers, which use low speed data transmission over short distances, Unscreened Multicore or Multi-pair Cables can be used.
• For the Interconnection of Data Processor, instruments and microcomputers where signal interface is a consideration, cables are generally screened.
• Minicomputers need medium speed transmission of data, and for these, interfaces with screen twisted pair cables are suitable.
• When signal speed is low, a braid screen is sufficient but for higher speeds a foiled screen or composite foil and braid screen is more suitable.
• One can use individually screened pairs to diminish the effect of cross talk, resultantly making possible smooth transmission over long distances.

• Conductor : Conductor material is Copper. It may be bare or tin coated to minimize oxidation and facilitate soldering. Conductors may be stranded or solid type. For higher cross section generally stranded type construction is preferred.
• Insulation : Insulation material depends upon the electrical and mechanical properties desired and the environments. The most common material is Polyethylene and PVC.
• Shields : Shields is provided to prevent harmful electrostatic interface. These are three basic reasons for providing an electrostatic shield in a cable. The first, and the 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 at 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. Two types of shields as given below are commonly used.
  Braided Copper Wire Shield : Braided shields are reasonably flexible, quite durable and offer a good balance of shielding properties. The drawbacks in braided shields are difficulty in terminating higher cable dimensions and cost. The practical limits of coverage are approach 96%.
  Aluminum Laminated Mylar Tape Shields : It consists of a laminate of rolled aluminum foil, which is bonded with a high strength adhesive to the mylar film. The tape is applied spirally of longitudinally and provides total (100%) electrostatic shielding. An un-insulated conductor, drain wire is provided in intimate contact with aluminum side of the tape for the ease of shielded termination. The drain wire may be of solid tinned copper or stranded tinned copper and serves triple purpose.
  
  • Provides easy and suitable grounding of the mylar-aluminum shield.
    
  • Acts as conductors in relay control of annunciator circuits.
    
  • Drains the accumulated static charges from the mylar-aluminum shield to ground.
• Sheath : PVC compound is generally used for sheathing purpose. It may have additional fire retardant (FR) or fire retardant low smoke (FRLS) properties. Polyethylene sheath is recommended for low temperature application and aromatic hydrocarbon surrounding. However, polyethylene sheath does not have flame retarding properties.
• Armor : Armoring is provided for mechanical protection and may be either of galvanized round steel wire or galvanized flat steel strips.
• Governing Specifications : BS - 5308 (Part - 1 & 2), VDE 0815, IS - 1554 (Part - 1), in general and customers specifications
