Precision-engineered copper grounding solutions complying with European IEC 60228, UNE 21186, and UNE-EN 62561 lightning protection standards across Spanish industrial facilities.
Spain stands as one of Europe's most ambitious clean energy leaders under the updated National Integrated Energy and Climate Plan (PNIEC 2023–2030), projecting over 76 GW of solar photovoltaic capacity and 62 GW of wind generation by 2030. In utility-scale solar farms across Andalusia, Extremadura, Castilla-La Mancha, and Aragon, electrical safety and system longevity hinge directly upon robust earthing grids.
The unique Spanish climate—ranging from hyper-arid, high-resistivity gravel terrains in central Iberia to saline coastal environments along the Mediterranean and Atlantic coasts—demands copper ground conductors with exceptional metallurgical purity, maximum corrosion resistance, and high current-carrying capacity during fault transients.
As a specialized manufacturer from China's electrical capital, Zhejiang Xingma Copper Industry Co., Ltd. bridges global tier-1 EPC contractors, local Spanish installers (*instaladores eléctricos*), and switchgear panel builders (*cuadristas*) with factory-direct bare copper ground wires, braided tapes, and custom-welded busbars tailored to Spanish regulatory standards.
Established in 2019 in Liushi, the capital of electrical appliances in China, Zhejiang Xingma Copper Industry Co., Ltd. is an enterprise mainly engaged in metal products, wire and cable processing and sales, and import and export of goods and technology.
The company revolves around the construction of a modern enterprise mechanism and mass production of mechanical automation. Our facility houses more than 300 domestic top-level manufacturing machines, including:
Our leading products include bare copper wire, copper braided wire, copper stranded wire, soft copper stranded wire, brush wire, carbon brush wire, soft connection series products, and metal stamping parts—deeply trusted and widely exported to international markets including Spain, Portugal, and across the EU.
The company abides by the Universal Declaration of Human Rights and major United Nations conventions, respects human and labor rights, opposes discrimination and harassment, respects each other, and is brave and determined to achieve and surpass itself. Relying on the manufacturing industry and taking scientific and technological innovation as the concept, we vigorously expand related industries and continuously develop.

Certified Quality System
Every meter of bare copper conductor is drawn from electrolytic cathode copper (Cu-ETP / CW004A) with 99.95%+ copper content, ensuring maximum conductivity and structural integrity.
High electrical conductivity prevents localized hot spots during high fault current discharges, guaranteeing swift dissipation to ground in Spanish photovoltaic inverter stations and high-voltage substations (REE grid).
Fully compliant with European lightning protection system component (LPSC) requirements and Spanish standards for early streamer emission (ESE) and Faraday cage installations on public and industrial buildings.
Bare copper forms a stable cuprite patina in aggressive acidic and alkaline Spanish soils, ensuring 30+ year design life without premature galvanic degradation or high maintenance costs.
Class 2, Class 5, and Class 6 stranded configurations (from 0.5 mm² up to 500 mm²) offer effortless bending around steel foundations, ground rods (*picas de toma de tierra*), and solar torque tubes.
Our integrated precision stamping and ultrasonic/exothermic welding facilities deliver finished ground jumpers with press-fitted tinned lugs tailored to OEM customer drawings.
Every shipment is accompanied by comprehensive 3.1 EN 10204 test reports covering tensile strength, elongation (≥30%), electrical resistivity (≤0.017241 Ω·mm²/m), and chemical purity.

For utility-scale solar farms across Spain, 35 mm², 50 mm², and 70 mm² soft annealed 7-strand and 19-strand bare copper wires are the most popular choices for perimeter grounding rings and inverter station equipotential bonding. For tracker bonding, customized flexible copper braids (16 mm² to 25 mm²) with tinned contact ends are extensively requested.
Yes. Our bare copper conductors and flexible connectors are manufactured strictly using ≥99.95% electrolytic copper (Cu-ETP), meeting or exceeding the electrical resistance and tensile strength requirements mandated by IEC 60228 (Class 2 / Class 5) and UNE-EN 62561 for lightning protection and safety earthing.
Absolutely. Leveraging our 300+ advanced manufacturing units—including middle drawing, automated cutting, high-tonnage stamping, and ultrasonic/press welding—we fabricate custom rectangular and laminated flexible copper busbars, pre-drilled to exact hole diameters and pitch for rapid installation in Spanish switchboards and battery storage cabinets.
Standard manufacturing lead times range between 10 to 20 days depending on order volume.
