Lightning & Earthing

Why Is Lightning Protection Important?

When a lightning strike occurs, it creates a surge of electrical current that can damage machinery and cause fires. If a lightning strike hits a facility and there is no protection system in place, the electrical charge will travel through the electrical system, damaging sensitive equipment and increasing the risk of fire. A lightning protection system will divert the electrical current from the facility and direct it back to the ground. A lightning protection system is designed to withstand the current of a direct strike, but smaller strikes may get through, which is why you must also have surge protection to protect against these smaller surges.

While the cost of adding lightning protection can be high, failing to do so can result in additional expenses down the road. A lightning strike can damage sensitive and expensive equipment, while also increasing your risk of fire and electric shock. Lightning protection mitigates the secondary effects of a direct strike by diverting the electrical current away from sensitive systems and preventing an explosion or fire.

  • Spark Gaps
    SKU: AT-050K

    AT-050K is the most appropriate means of joining the different earth connections when this
    connection cannot be made directly as, for example, it may cause corrosion problems.
    When a discharge occurs and the voltage increases in the earth connections, the spark gap
    will activate, directly joining the earth connections and thus preventing current passing from
    one to another through equipment or internal installations.


  • APLIFILL Graphite Powder
    SKU: AT-032L

    Aplifill is a highly hygroscopic compound and retains moisture around the conductor when used to fill any excavation made for soil replacement. Available in a Graphite Powder mixture or Clay mixture.


  • Apliweld® Secure+
    SKU: Apliweld

    The innovative tablet format of Apliweld® Secure+ and the electronic ignition offers efficient results, saving costs and providing an extra in safety.


  • ESE Air Terminals
    SKU: ESE-Air

    ESE air terminals emit a continuous upward leader before any other object, which increments the protection zone and provides lightning current a safe path to the earthing, thus protecting people and structures within its protection radius.


  • Franklin Rods
    SKU: AT3w-Rods

    Lightning protection using franklin rods and meshed conductors is used to share and dissipate the lightning current through a network of down-conductors and earth terminations.


  • Storm Detector
    SKU: AT3W_Storm

    The ATSTORM® is an expert local early warning system for risk prevention against lightning storms. The ATSTORM® system monitors both the electrostatic field and the electromagnetic field – able to detect both the electrical storms that approach the area to be protected, as well as those that are forming above it.

    The ability to monitor all phases of a storm, from cloud electrification through to its dissipation, makes ATSTORM® a complete advanced data system, which alerts to initiate preventive actions that minimize the risks caused by lightning impacts.


  • APLIROD® dynamic electrode
    SKU: AT-012H

    A lack of free ions in the surrounding ground is detrimental to the correct performance of the earthing. Earthing systems using dynamic electrodes are based on the contribution of ions to the ground.

    The system mainly consists of a copper electrode (APLIROD®) filled with a mixture of ionic compounds. The moisture condenser absorbs environmental moisture and dissipates it in the soil surrounding the electrode, adding free ions and gradually lowering the resistivity of the soil.


  • Graphite electrode
    SKU: AT-070H

    ø150 x 600 mm graphite electrode.


  • 254µm copperbond earth rods
    SKU: AT-016H

    Copperbond earth rods of a high quality which comply with even the most demanding regulations in order to achieve long-lasting earthing.

    Electrolytically coated with copper which is 254 µm thick and 99.9% pure, with a proven resistance to corrosion. This type of electrolytic coating prevents cracks or fissures, which may be caused in the outer layer of the earth rods with mechanical coating.

    Using the appropriate accessories, threaded copperbond earth rods enable the electrode to extend in order to obtain better earth resistances.


  • Copperbond earth rods couplings

  • Solid copper earth rods

  • 500 x 500 x 2mm earth plate
    SKU: AT-050J

    The use of earth plates as electrodes significantly reduces the resistance of earthing in stony grounds, as it increases the area of contact between the electrode and the ground.


  • Copper lattices and grids
    SKU: AT-070J

    Mesh earthing systems are a more cost-effective option than earth plates and still work well in stony ground, reducing the step or contact voltages that may occur.

    To be installed horizontally.

    Recommended to avoid step voltages in public buildings with low resistivity soil.

    CONDUCTIVER PLUS is a ground enhancing gel with low solubility which is, nonetheless, very hygroscopic.
    CONDUCTIVER PLUS is characterised by:
    Its capacity to create partially ionized electrolytes, with a high charge and capacity to retain water and form gels.
    Remaining in the ground for a long time, thanks to the formation of bonds with the particles.
