Safety measures while dealing with Underground cables



This blog focuses on approach while dealing with underground cables, which is often overlooked. It can be harmful and hazardous if not dealt right.
One of the main dangers which may arise when digging is that of possible injury from underground power cables. Injuries resulting from damage to live power cables are usually caused by the explosive effects of arcing current and by associated fire or flames. This can occur when the sheath of the cable and the conductor insulation are penetrated by a sharp object, such as the point of a tool, or when the cable is crushed severely enough to cause contact between the sheathing and one or more conductors.
This typically causes severe and potentially fatal burns to the hands, face and body.
Direct electric shock is also a possibility. Furthermore, some high voltage power cables are oil filled and oil can ignite. Electrical fires can be catastrophic if damage spreads to other nearby services such as gas pipes. Such accidents are caused by failure to take all reasonably practicable precautions to prevent accidental contact with underground services.
Recommended methods and procedures, which, if adopted, will provide a positive approach to the elimination of these tragedies.

The basic elements of a safe system of work involve:

1.    Correct use of Plans (to aid location of power cables)

Before starting work it is essential that you have all of the cable records for the location and that these are kept on site at all times while work is proceeding. Make sure that they are up-to-date; that they cover all cable voltages at the location; that you understand how to interpret them; and that they are fully utilised both in advance of commencing digging and throughout the full duration of the work.

2. Use of Cable Locating Devices

Suitable cable locating devices should be used in conjunction with the cable plans to determine as accurately as possible the position of underground cables in or near the proposed work area.

3. Use of Safe Digging Practice

These three key elements complement each other and all three should be used when working near buried services.
LAPP, one of the leading cablemanufacturers in India, provides cable based on the application. Therefore, you will find wide range of the cables, these cables are tested under extreme circumstances. Therefore, you can rely on the quality and be sure that you would be safe. Do visit the official website of LAPP to check the available options of the cables.

Oil Resistant Cables: Know How Important They Are!

Demands of the industrial environment are ongoing, with ever-changing trends. Cables that were able to sustain functional and operational integrity a decade ago would not be adequate to survive in the environment of a present day manufacturing site. Everywhere, from the renewable energy industry and automotive assembly plants to the factories that manufacture small office machines, and even in some commercial buildings, oil resistant cables have become increasingly important. Oils serve a dual-purpose in industrial applications, both as a coolant and lubricant, depending upon the requirements mandated by the end use application. Sustaining trouble-free cable operation under harsh chemical and environmental conditions reduces costly manufacturing downtime and helps to eliminate or minimize periodic maintenance and costly cable replacement. All of the factors mentioned play a major role that is critical to a consistent, smoothly run manufacturing operation, which in the end res...

The future with Fiber Optic cables

Internet penetration in India is a major concern and will be for a while. Only 400 million of India’s 1.2 billion strong population is online, after all. As fiber optic technology continues to revolutionize the telecommunication and data capabilities of a range of industries, the average individual may not understand the advantages that fiber optic technology provides for us in our everyday life. To better understand the advantages and capabilities of fiber optic technology, we’ll outline a few basics touch points of fiber optics and their contribution to our everyday lives. Let us catch up on the benefits of optical fiber over traditional metallic wire. Benefits of Optic Fibers Vs. Traditional Metallic Wiring? Besides the fact that conventional metallic wiring is far more expensive to produce, fiber optics deliver a superior amount of quality, convenience, and durability currently unmatched in telecommunication technology. Although the majority of our practical ...

Overview of LAPP as Company

Here’s where it all started… In the early 1950s, the revolution in industrialization led to a massive demand for cables and conductors. When Oskar Lapp witnessed this development, he posed a question to himself: "How can I optimize the current method - the time-consuming manual inserting of single cores and switching strands into the outer sheaths?" In a while he got his answer. Thus the idea of the world’s first ever industrially produced flexible, colour-coded signal cable - ÖLFLEX® was conceived by Lapp and LAPP Group came into existence. When it was still something new, in 1959, LAPP gave his products brand names and it quickly allowed them to be distinguished from their competition. Even in this, Oskar Lapp became a front runner to become the first person offering catchy branding that are still very much in use. LAPP’s most well-known brand is ÖLFLEX®, that has secured a place in the history of cable manufacturers India and the rest of the world. In 1979, LAPP...
