Grounding Systems

Spina Group designs and supplies industrial grounding systems that guarantee the safety of goods and people, using high quality components to protect against atmospheric discharges for earthing systems.

Grounding means the set of actions and systems aimed at bringing a metallic element to the electric potential of the ground. It is important to ensure grounding where dangerous situations can occur when parts of the electrical system that are not normally live, due to failures or unforeseen events, acquire an electrical potential with respect to the ground.

Earthing, in particular, protects people from the risk of electrocution, in practice from “indirect contacts”. It consists of one or more interconnected dispersers placed in the ground and a series of earth and protection conductors which connect the aforementioned disperser to the user appliances.

Our Offer

Ground Rods

A wide range of earth rods, such as round section ground rods, T section ground rods, L section ground rods, X section ground rods, ground plates and accessories, designed according to the size of the currents that it disperse into the ground. 

Lightning Rods

Spina Group offers a wide selection of accessories both for the protection against direct and indirect electric shock that ensure protection of the system from atmospheric discharges.

Equipotential Connections & Accessories

A wide selection of clamps, plates, turnband, bonding bars, terminal boards, bar insulators and bridge cables suitable for earthing stainless steel, copper and nickel-plated brass pipes.

Bare & Insulated Conductors

Tools for electrical connections, electromechanical applications, transformer rooms compliant with national and foreign regulations. Sections and shaping different from the standard can be supplied on request. The products comply with the main national and international standards and with specific customer requests.

Earthing Pits

Spina offers a wide selection of inspection sumps in anti-corrosive plastic, available with removable bottom, carriageable cover, suitable for cable and earthing connection.

Surge Arresters

Overvoltage surge arresters (also called SPD – Surge Protection Device) are mechanisms that allow to protect electrical equipment from overvoltages by absorbing the generated current. They can also be inserted in an already existing system in order not to modify the operation of the system.

Oil&Gas

Rijeka Refinery — Urinj — Kostrena

The Rijeka Refinery, located in Urinj, Croatia, is an oil refinery that processes crude oil to produce fuels and refined petroleum products. The plant has undergone a major modernization project worth approximately €700 million, aimed at the construction of a Delayed Coking Unit and associated facilities. The project enables the refinery to process a wider range of crude oils, including heavier grades, with a capacity of up to approximately 4 million tonnes per year.

Bioenergy

Sannazzaro Revamping

The Sannazzaro Revamping is a project for the partial conversion of Eni’s Sannazzaro de’ Burgondi refinery, in the province of Pavia. Developed by Eni, the project involves the conversion of the Hydrocracker HDC2 unit, the construction of a pretreatment plant for waste and residues, and the upgrade of logistics and auxiliary infrastructure. The new biorefinery will have a capacity of approximately 550,000 tonnes/year and will produce HVO diesel and SAF-biojet, contributing to the decarbonization of transport and to the expansion of Eni’s biorefining capacity.

Petrochemical

Beaumont 3000 MTPD Synloop Ammonia Plant

The Beaumont New Ammonia Project, located in Beaumont, Texas, USA, is a major lower-carbon ammonia facility with a production capacity of 3,000 metric tonnes per day (1.1 million tonnes per year). Owned and operated by Woodside, the project is designed to expand the supply of lower-carbon ammonia for applications including power generation, marine fuels, and industrial feedstock. A key milestone was achieved in December 2025 with the successful production of first ammonia during commissioning.
