ConduDisc is changing the way companies approach earthing systems.

Inspired by our trials pre-casting Conducrete slabs for large telecoms companies,  the ConduDisc was developed for the rapid deployment of timber electricity transmission poles crossing the Canadian wilderness. The ConduDisc empowers a workforce to achieve a functional earth in as much time and effort as it takes to drop a stone in a hole.

The technology has been adapted to enable installations to achieve electrical safety with the same speed and ease without using earth rods. The following short clip will demonstrate the method used for EV Charge Points.

A corrosion proof, simple and fast to install earthing solution ideal for:

  • Distribution poles (where earthing is required)
  • Pad mount transformers
  • Transmission poles
  • Rail infrastructure
  • EV Charging infrastructure
  • Telecommunications cabinets and exchanges
  • Modular construction

It has the lowest total lifecycle cost when measured against other methods and is permanent so maintenance free.

"Having installed many EVSE chargers, our most significant bugbear has always been obtaining the required earth resistance readings to ensure that we remain compliant. I have to say it’s not often that you find a golden nugget, but on this occasion, this is what we found. The ConduDisc is easy to install and delivers resistance readings way within the requirements as set out by the IET. In summary, it’s a great product, at a great price and does more than it says on the packet, we will be using the ConduDiscs on all our future installations."​

ConduDisc replaces traditional earth / ground rods

ConduDisc - earthing without rods conductive polymer in disc format

When you compare the ConduDisc to conventional earth rods it becomes abundantly clear that the earth rod is yesterday’s technology. In fact it isn’t even yesterday’s technology, there have been far smarter and more effective solutions available for a few decades. Part of the reason that earth / ground rods have remained popular is because they are easy to understand what they are and how to install them. That being said “whack metal rod in ground” is often easier said than done, particularly in compacted ground, urban areas and rocky environments. 

Earth / ground rods are causing growing health, safety and longevity causes in the construction world. Not only have RIDDOR reportable incidents associated with earth / ground rods increased, so too have investigations into failed earthing systems. In the eyes of proactive consultants and constructors earth rods represent too great a health and safety risk to permit to be installed, and the prospect of being liable for an earth system with unknowable service life represents too great a financial risk.

Then there’s the ConduDisc: as easy to install as dropping a stone in a hole, and has decades and decades of service life; at just 350mm x 50mm, this conductor has a contact surface area greater than 3m of earth rod, and yet fits easily in a small excavation. So long serving is the ConduDisc that it is highly likely to outlast the item for which it is providing an earth. It’s more effective and managing fault electrical current and more reliable. The health and safety risks associated with installing rods are removed so the prospect of RIDDOR fades away. 

Rather makes earth / ground rods a bad idea on every front…

What about in rocky areas?

When faced with dry, rocky soils ConduDisc and ConduFlow or Conducrete provides a superior electrode to soil connection.

If the ConduDisc & ConduFlow or Conducrete combination is placed at the same location, a low impedance reading is achieved with no change in excavation backfill materials and duration and frequency of fault current events will decrease.

Can ConduDisc be used differently?

Beyond being an ideal permanent earthing method ConduDisc is being used in a variety of ways that conventional methods would be unsuitable to replicate. One way it is being used is for temporary earthing for structures such as site cabins, temporary transmission masts, event or festival earthing. Then there is the more long term installation-type such as on land under lease. The following clip will demonstrate a solution for solar (PV) farms that also considers this.
