SMART CONSUMER - Choosing the right Power cable for your Genset

All of us enjoy electrical appliances, be it domestic or commercial. But we tend to forget that there is an underlying network of cables supporting the entire system. High technology is involved in the making these cables, which makes them withstand tough conditions for years.

We strongly believe that basic knowledge about the cables are a must for them who own a genset. Choosing the manufacturer recommended Power Cable for your genset is important. To save a few bucks we are often tempted to use cheaper options which may lead to many issues like the ones discussed below.

Undersized cable will generate excessive heat which may melt the protective cover of the cable leading to hazards like fire or electric shock.

In case there is a short circuit, an undersized cable will not withstand the fault current. The cable may melt, burn or even cause severe damage to connected equipment even before any tripping mechanism may work.

Powerol recommends the use of 3.5 Core Armoured Power Cable for three phase and 2 Core Armoured Power Cable for single phase gensets.

Let us understand what this actually is:

3.5 Core cables will have 3 stranded wires for R, Y, B Phases, with diameter X and one stranded wire for Neutral with diameter X/2.

A 2 Core cable will have one Phase wire and one Neutral wire of same diameter.

3.5 Core Cable

2 Core Cable

Construction of 3.5 Core and 2 Core Armoured Cable:-

Weather Proof Coating : Withstands every weather condition.
Steel Armour : Provides the mechanical and tensile strength to withstand toughest conditions.
Extra Insulation : Under the steel insulation this extra insulation lies.
Core Insulation : Prevents short circuit. Insulation material should be XLPE if underground cable is used.
Stranded Conductor : These are the current carrying conductors.


Overheating due to usage of undersized cables and loose thumbing causes most of the electrical failures. Choosing the right size and type of Power Cable is a critical technical decision. Consider every possible factors before making a purchase decision.

The size of Power Cables (generally referred in Sq.mm) primarily depends on the Ampere rating of the Genset. Copper is a better conductor compared to Aluminium, they are the best material to be considered. For the same amount current lesser diameter of Copper cable can be used compared to Aluminium cable. Downside of using a Copper Cable is they are heavier and costlier than the Aluminium Cables.

While laying the cable try to keep the bends minimum and avoid sharp bends.

Avoid joints, use a continuous cable. In case a joint is unavoidable the work must be done by a qualified person. Incorrect joint will lead to expensive failure in future.

Use right size of thimbles and proper crimping to make a proper terminal connection.

For proper terminal connection the contact area must be adequate.

Improper termination will lead to local heat generation. Which will lead to failure.

Avoid Point connection arising out of improper position. Gaps between leads and terminals, in such cases the Nuts or Bolts will carry the load current. Normally they are made of Mild Steel and are not designed to carry high current.

Do consult an authorized person before purchasing the Power Cable. Powerol has a highly competent team of genset installation specialist. You may contact them for any guidance.

There are large variety of Power Cable types to suit different kind of operation. Including all of them in this blog will make it little overwhelming for the reader. If you are interested to know more about Power Cables, do let us know in the comments section, we will be happy to help you.

Gas Generator – Entering the greener future.

Diesel Generators have been the unchallenged king in the field of backup power generation since ages. Modern day diesel generators are technologically very advanced and meets every stringent emission norm enforced by the Government. While the Government is still pushing the limit for the quality of emission, the Diesel Generator manufacturers are working continuously to make a more fuel efficient and environment friendly products.

While the technology for Diesel Generators was progressing, Natural Gas technology also came a long way and made significant inroads in the market. Modern Gas Generators are very silent, ensures very low operating cost and most importantly the emission from a Gas Generator contains ZERO Particulate Matter.

The emission from Automobiles and Generators significantly contributes in the production of harmful Green House Gases (GHG). The CO2 and N2O gases hold back the heat which tries to go back to space from the surface of the earth, this makes the atmosphere warmer. The carbon particles (commonly described as Particulate Matter or PM) present in the emission absorbs a huge amount of heat and makes the atmosphere warmer. This is one of the major causes of global warming which is causing havoc worldwide.

These emissions make the air extremely harmful for our health. Quality of air in all major cities in India are worsening steadily. Air Quality Index (AQI) is a scientific method of measuring the air quality and currently Delhi is topping the chart in India for having the worst quality of air, indicated by a higher AQI number. Delhi is having the highest Particulate Matter pollution in India and currently the city with 6th worst air quality in the world, if the entire NCR is added then it is the 2nd worst city in the world.

The Particulate Matter present in the emission gases are often denoted by PM2.5 and PM10. The PM2.5 refers to the particulate matter with a diameter less than 2.5 micrometres. These fine particles are dangerous for our health. Due to their small size they can directly enter our lungs. They can disturb our entire Respiratory System and Cardiovascular system. 

Air pollution is a global concern. There can’t be any excuse for inaction. Our sincere commitment towards a greener future is articulated by the launch of India’s first CPCB 2 approved Natural Gas Genset. It offers ZERO PARTICULATE MATTER EMISSION which makes it an environment friendly Generator.

Powerol is closely working with natural gas suppliers to provide gas pipe lines at your premises. Piped Natural Gas supply will eliminate the need of periodic refuelling and will ensure good quality of fuel.

We human beings have destroyed enough of this earth in the name of development. The use of fossil fuel which gave us the power and mobility, literally transformed our lives, but we did not use it responsibly. Our own invention for human wellbeing is turning against us.

It is high time for us to act responsibly. The choices we make today will decide whether we are heading for a greener future or a disaster.

Thankfully today we have green technologies and innovations at our disposal which promises to protect the environment.

Powerol is dedicatedly working on green technologies like Natural Gas Generators, waste energy management, Battery for Telecom Sites, Solar Power for Telecom sites, and so on.

You can be a part of our green journey either by owning a green technology product or by spreading the awareness. We are all ears to hear from you. If you have any questions or need any guidance, feel free to contact us. We will be happy to help you.
