Earth Enhancing compound
An lightning earth is integrity of any lightning protection system. The final stage of a lightning protection system it is essential a low impedance earthing and it will be provided a safe and efficient dissipation of the lightning discharge into the ground.
The type of lightning earth is dependant on site conditions, the seasonal changes and the soil condition. A typical lightning earth may utilize earth rods, tapes, clamps. If additional improvement required, the earthing compounds in varying configurations to provide the lowest impedance earth.
A SAFE EARTHING SYSTEM
- A low resistance earth allows lightning energy safe dissipation into the ground mass.
- A low earth impedance provides a path for lightning impulses through the earthing electrodes to the ground mass.
- A correctly sized earth rods can withstand high fault
currents.
A good quality earthing hardware, which presents a high level of conductivity and minimizes the risk of corrosion. Copper accessories are the most commonly used in achieving the above requirements.

- Obtaining a good earth resistance has always been a problem in soils of poor electrical conductivity.
- With the earth enhancing compound many of your difficult earthing installations can be greatly improved.
- Reduce the number of the
workmanship and high guaranty of the network in the site area.
- The compound consists of a chemical solution of good electrical conductivity,
when mixed with warm water and poured onto the earthing grid and surrounding soil.

Result:
- Improvements in earth resistance of 50% to 90% are not uncommon when using the earth enhancing compound.
- It must be stressed that every application is different and therefore results will differ also. Generally specking, one 10 kg will be sufficient to produce a satisfactory earth resistance over a 5 metres earth wire in the worst soil conditions to 15 metres in poor soil conditions.
- In exceptional cases, the question may arise as to
whether any soil improvement should be undertaken when no significant
improvement can be obtained by reasonable endeavour. It must be remembered
that any reduction in soil resistance gives more security to your
installation.
