The public sector undertaking plays a very crucial role in the economic development of a country. Limited availability of resources and lack of abundant scope in the private sector has led to predominance of the public sector in the economy. Increased investment on the public sector has also accelerated the growth of sectors like railways, nuclear power, defence, etc. It is safe to say that public sector is an amalgamation of industries dealing with infrastructure, trade services industries and consumer goods industries.
The main goals of the PSU are to ensure supply meets demand, even distribution of income is appropriately maintained and most importantly the worker’s interests are protected. Recently, PSUs have become a lucrative job opportunity for several who have been looking for a way to ride out the global economic meltdown.
PSUs are pivotal towards the development of a country for numerous reasons. One being, it promotes a balanced growth in all the regions of a country. Since they are in for the long run, PSUs provide a better line of view for the future status of the economy of the country. They promote public welfare as it is their primary objective. Public sector undertaking improves the scope for coordination among the industries and also eliminates the chance of monopolizing of operation.
PSU businesses thrive on great client rapport. This depends on the visibility of the company in the market and how capable their vendors are. PSUs always have cost and safety as their primary concern. They look for safety certifications as well as the company’s stand in the international market. PSUs consider all these criteria because their final motive is public welfare and development of the country. It is the attention to these minute details which enhances the credibility and recognition of this industry in both domestic and international markets.
Significant characteristics of cables used in PSUs
PSUs have safety of the general public as their primary concern. They require cable solutions which are not only of superior quality but also are non-hazardous. Different kinds of industries are maintained by the PSU and their cable requirements also vary. For example, cables used in the nuclear power research centers must be radiation resistant, whereas the ones used in railways must be abrasion resistant and oil repellant among other things. Hence, it is pertinent that the cables can withstand the demands of that industry with utmost efficiency. The cable characteristics mentioned below are a must for businesses under PSUs:
- With increasing popularity of compact machines, the PSUs are not far behind. Cables for these machines have to address the space constraints. They should possess lightweight construction and yet be powerful.
- Cables used should be secure against failure and provide long lasting connection.
- In today’s economy, a company cannot waste its resources on obtaining cables. The cable should be cost effective without compromising the performance value.
- PSUs manage many manufacturing companies. The machines in this sector are prone to vibrations. Hence, the cables should be capable of withstanding vibrations and should not give way to loose connections.
- Cables should possess superior chemical, mechanical and electrical properties. They should be halogen free, fire retardant cables.
- Cables should be international-standards approved. It is mandatory that all components satisfy specific international safety codes and regulations.
- The cables should possess superior flexibility and should even be able to withstand torsion stress in robotic applications which are utilized in the defense sector on a regular basis.
- The cables should have joint free construction to reduce data attenuation in communication cables and to continue seamless power transmission in power and control cables.
- The cables must comprise of abrasion resistant insulation.
- Cables are an important part of machines. Considerable heat is produced during their operation. The cables should be capable of withstanding the temperatures (the maximum temperature is to be dictated by the application).
- The industry demands cables that is free from oxidation to prolong their shelf life
What are the different cabling solutions for varied applications in the industry?
Superior Quality OLFLEX cables with High Performance Delivery: OLFLEX cables could be used for power and control applications. For building installation, they are supplied with OLFLEX STATIC cable. These cables are closely shielded and consist of doubly insulated PVC single conductor for fix laying. Because of their low costs, this cable was ideal for the application. Its double-insulated single core made it ideal for fixed installation both indoors and outdoors.Because of its robust decontaminated sheath, the cables do not require any additional conduits. These cables are also at par with the safety standards and all cables are radiation and flame resistant.
Seamless Data Transmission made Possible with UNITRONIC Cables: Depending on the data transfer requirement, data transmission cables are also provided. The cable provided are from a wide range of UNITRONIC cables which are used for panel indication, motor control, AC control and other automation related applications. All cables were provided with copper braided screening to prevent electromagnetic interference effects.
UNITRONIC PROFIBUS cables are provided for instrumentation purposes. These cables are aluminum taped cable and has a halogen free outer sheath and enhanced flame retardant features. They are used for transmitting analog signals in the ammeters, voltmeters, wattmeter etc.
