Alongside our pure copper conductors, we supply synchronized earthing rods, stainless mesh containment, structural walkway grating, and specialized composite infrastructure for complete turnkey substation and facility deployment.
In high-voltage electrical installations, petrochemical hubs, and mission-critical data infrastructure, the earthing and lightning conductor system is the supreme safeguard against catastrophic dielectric breakdown, touch-and-step voltage hazards, and irreversible equipment destruction. In Romania, electrical design adheres strictly to the harmonized European standards alongside specific national grid codes enforced by Transelectrica (the Romanian National Power Grid Company) and ANRE (Autoritatea Națională de Reglementare în domeniul Energiei).
As a seasoned manufacturer, we produce high-conductivity copper earthing strips (bare and electro-tinned) utilizing electrolytic tough-pitch copper CW004A (Cu-ETP according to EN 13601) and oxygen-free copper CW008A (Cu-OF). The structural composition exhibits minimum copper purities of 99.90%, ensuring an electrical conductivity that regularly surpasses 100% to 101% IACS (International Annealed Copper Standard). This metallurgic refinement ensures that under severe short-circuit scenarios (such as single phase-to-earth faults within 400kV and 220kV transmission substations), our conductors dissipate high-amplitude transients with minimal resistive thermal rise, eliminating the risk of thermal runaway, underground sintering, or hazardous surface flashovers.
Fabricated via continuous casting and cold rolling, retaining a clean micro-grain boundary structure that prevents brittleness and guarantees maximum current transmission density under severe discharge.
Uniform electrolytic tinning (8–15 µm) to BS EN ISO 2093 prevents galvanic oxidation when bonded to galvanized steel reinforcing meshes or acidic Romanian chernozem subsoils.
Rounded or smooth edges minimize localized electrostatic discharge concentration (corona reduction) and eliminate damage during direct mechanical bending inside switchgear basements.
Contractors and structural engineers across Romania require precision-slit and mill-annealed copper flat tapes matching both standard metric trench profiles and bespoke busbar dimensions. Below is the specification reference covering standard supply lines used in industrial, utility, and rail applications.

*All strips can be specified bare or with uniform electro-tinning (minimum thickness 10 μm) compliant with ASTM B545 and EN ISO 2093. Custom cross-sections, cut lengths, prepunched mounting slots, and radiused corner geometries are manufactured directly to engineer drawings.
Romania represents one of Eastern Europe's most dynamic industrial hubs, undergoing comprehensive power grid upgrades, major renewable energy investments, and transportation modernizations. The geographical and geological diversity of the country requires tailor-made earthing solutions to handle specific local environmental constraints.
Substation retrofits in Craiova, Suceava, and Cernavodă require 40×4mm to 50×5mm bare copper tapes arranged in deep meshes to safeguard against transient surge levels exceeding 40kA during phase-to-earth faults.
The high soil resistivity and coastal salinity of the Dobrogea plateau (Constanța, Tulcea) necessitate tinned copper earthing tape rings surrounding turbine foundations to avoid atmospheric chloride corrosion and dissipate lightning transients safely.
In flammable refinery zones (Brazi, Teleajen), our copper tapes provide zero-spark equipotential bonding along hydrocarbon pipe racks, tank farm enclosures, and linear cable trenches covered by our anti-corrosion trench covers.
Equipotential Signal Reference Grids (SRG) utilizing 25×3mm flat copper tape laid under raised floors to prevent high-frequency EMI/RFI noise and electrostatic discharge from damaging enterprise IT equipment.
CFR modernization initiatives along Pan-European Corridor IV deploy tinned copper ground strips for trackside signaling shelters, traction sub-stations (25kV 50Hz), and catenary mast grounding, tolerating dynamic vibration.
Hydro assets operated by Hidroelectrica across the Argeș, Lotru, and Olt river valleys utilize heavy 50×5mm and 50×6mm copper earthing strips submerged in tailrace tunnels and generator turbine galleries exposed to humid environments.
The Romanian energy sector is undergoing a historic structural reconfiguration driven by EU climate objectives, Modernisation Fund subsidies, and the National Integrated Energy and Climate Plan (PNIESC 2021–2030). These structural shifts impact grounding engineering practices directly:
Romania aims to add over 5.5 GW of solar capacity by 2030. Modern PV installations operate with high DC system voltages (1500V DC), demanding lower grid impedance to eliminate ground fault risks. Engineers specify continuous perimeter grounding rings using 30×3.5mm and 40×4mm copper tape coupled with exothermic weld joints or heavy-duty brass mechanical clamps to minimize contact resistance.
Romania represents a unique seismic zone in Eastern Europe, primarily driven by the intermediate-depth earthquakes originating from the Vrancea tectonic nest. Rigid earthing bars without ductility crack when subject to sudden soil liquefaction or lateral shear in the Muntenia and Moldova regions. Our copper strips are cold-rolled and vacuum annealed to achieve high elongation (>35% on 50mm gauge length), ensuring that underground earthing rings maintain structural continuity even during severe seismic displacement.
While galvanized steel strip (bandă zincată) has historically been utilized across agricultural plots for basic residential earthing, engineering consultancies (such as ISPE and Tractebel Romania) increasingly mandate electrolytic copper strips for utility-scale and industrial infrastructure. The extensive presence of chernozem and alluvial soils with acidic pH levels and moisture fluctuations rapidly consumes zinc coatings, causing steel rust and earthing failure within 7 to 10 years. Pure copper systems offer an operational lifecycle in excess of 45 to 60 years without degradation, delivering superior Return on Investment (ROI) over project lifetimes.
Drawing on an industrial manufacturing pedigree honed through precision engineering, high-tonnage electroforging, and metallurgical fabrication, our facilities operate under an uncompromising quality management system certified to ISO 9001:2015, ISO 14001:2015, and ISO 45001:2018.
Every shipment bound for Romanian customs clearance is accompanied by verified 3.1 inspection certificates documenting chemical purity (ICP-OES analysis), electrical conductivity (% IACS), tensile properties, and dimension tolerances.
Our earthing strips meet the mechanical and electrical performance requirements for lightning protection system components (LPSC) Part 2: Requirements for conductors and earth electrodes, matching Romanian standards cataloged by ASRO.
We supply more than just standalone strips: our customers receive an integrated package of stainless wire mesh cable trays, electroforged floor gratings, copper-bonded ground rods, and trench access plates engineered to work together without galvanic incompatibility.
Exporting to Romanian EPC contractors requires rigorous packaging to withstand multimodal transit. Every coil of bare or tinned copper tape is wrapped in moisture-resistant volatile corrosion inhibitor (VCI) film, strapped securely with non-ferrous banding, and mounted on heat-treated, fumigated ISPM-15 compliant wooden pallets or enclosed wooden crates. Clear color-coded labeling specifies the profile, batch code, net weight, coil length, and CE declaration of conformity.
Whether you are designing a 400kV transmission substation, deploying an extensive utility solar farm across Dobrogea, or upgrading refinery facilities in Ploiești, our engineering team will calculate fault current cross-sections and formulate a competitive, export-ready supply plan.
