Control cables have a wide range of applications, they are used in the most critical mechanical and industry production units like connecting electrical components, secondary switching of remote-control starters and regulators, protective relaying and automation purposes and most importantly in transmitting signals which further help in regulating and controlling the functioning of the machines. Control cables are also known for their multi-functionality in instrumentation cables, multi-core cables, motor cables, robotic cables and control flex. Since these are critical electric components which involves risk and danger, seek the expert guidance from the best manufacturers and dealers to ensure you receive the most genuine products.
Mechanism and Composition – Generally a control cable comprises of single copper or aluminum wires which again is made up of either four to 61 strands with a cross section of 1-10 sq mm and for cross sections from 4-10 sq mm the number of strands does not exceed ten. These are carefully insulated with rubber, polyethylene, or polyvinyl chloride and well sheathed with lead or plastic. Control cables function like that of a bicycle. The control cables actually control the movement of cables and wires carrying heavy or medium electricity load just like the brakes of a cycle regulate and control the movement and direction in which the cycle travels. It is made up of a plain copper conductor, sheath and a galvanized steel armour. All control cables do not have an armour, some contain PVC compound on top of the sheath. The PVC is present in almost all the control wires and it provides the necessary strength to the critical functioning cables and wires.
Application of Control Cables – Control cables are used in critical application areas where heav y electromagnetic pressure is required to be handled, like in automation industry of food and beverage domain.
Application in USSR – Control cables are manufactured for voltages ranging from 660 volts in AC and up to 1,000 volts in DC. It can also be used for ambient temperatures ranging from – 50° to 50°C. For insulated control cables, the temperatures can be increased to 65°-70°C.
Types – There are mainly 3 types of control cables used widely, as described below:
- CY Control Cables – These are used in interference-free transmission where there is high degree of circuit integrity and interference prevents transmission of signal in low or medium voltage installations
- SY Control Cables – These are comparatively tougher and a robust cable, which promises mechanical protection. There is a range of SY Cables, especially designed with a protective layer of galvanized steel wire braid and transparent PVC outer sheath. These provide a strong mechanical protection layer. A longer lifespan means reduction in costs in the long run, which is the ultimate benefit of control cables
- YY Control cables – These are used in several applications for use in control, signal and power cables. They have stronger external sheath which protects the cables from acids, corrosive substances, oils, grease and other reactive substances.
Remember, these Control cables India are used in the critical industry units of mechanical and electrical applications and it involves immense risk and danger of electricity. So make sure these are installed by the trained mechanical staff from the consultant leading manufacturers. Also check for the quality certification while you finalise these control cables for your project. All the best!
