This project will have 158.17 MWdc of solar production and 1,296 MWh of battery storage capacity. The project will also include 218,160 725 W solar modules mounted on 4,040 single-axis trackers. The panels will also receive support from 18 transformer stations. Sidon Solar will also install 324 Huawei Luna2000 battery packs on a 30,967-square-meter site. The electricity generated by this project will be evacuated to the Entre Rios substations via a 220 kV transmission line. The 5.7 km line will have a single circuit and a normal capacity of 170 MVA. The interconnection between panels, trackers, BESS, and the transmission lines will depend on reliable electrical connections, insulation, grounding, protection equipment, and mechanical components. These components include copper compression terminals, clamps, grounding hardware, cable accessories, and structural fittings.

    Copper compression terminal lugs form a permanent, gas-tight, and low-resistance electrical link by cold-welding the conductor strands to the lug barrel. The compression lugs reduce resistance at the connection site, preventing heat accumulation and power loss. UV exposure, heat cycling, and moisture all pose challenges for solar infrastructure. Tin-plated copper lugs aid to prevent oxidation and corrosion in outdoor situations. Copper compression terminal lugs ensure a gas-tight seal, preventing vibration-induced failure. Copper compression lugs in BESS systems ensure stable inter-cell and inter-component connections. They terminate finely stranded flexible cable without breaking the strands. They ensure the connections withstand fault currents, extreme weather, and decades of service without maintenance. Compression lugs provide the mechanical and electrical integrity and prevent rotation and loosening from vibration.

    Quality assurance for copper compression terminals used in solar and storage infrastructure

    Copper compression terminals provide a low-resistance electrical and mechanical interface for wires and equipment. They are crucial in utility-scale solar farms, BESS, and transmission systems that need dependable connections to function under demanding electrical conditions. Copper compression terminals need consistent production quality to cut connection failures across the facility. Conducting QA ensures that terminals retain dependable connections between PV cables, combiner equipment, inverters, transformers, grounding systems, and other electrical components.

    Compression terminal specifications

    Reliable terminals serve to limit the likelihood of overheating and connection degradation in battery racks, DC collecting systems, busbars, power conversion systems, and switchgear. Effective quality assurance reduces the probability of high-resistance connections, overheating, conductor pull-out, corrosion, premature failure, and unplanned outages. The QA process covers material quality verification, dimensional and manufacturing inspection, compression performance testing, electrical resistance testing, and corrosion resistance. QA helps ensure that the terminal does not crack, deform excessively, or release the conductor during service.

  • Bolted terminals: Powering Peru’s energy efficiency

    Wind and solar hybrid project

    Peru’s power sector is now starting an investment cycle that includes the construction of generation and transmission facilities. The country currently has 33 power production projects under construction. This investment of $6.5 billion is expected to result in over 5,000 MW of new installed capacity between 2026 and 2036. The project includes eleven solar power plants, five wind farms, sixteen hydropower projects, and one natural gas-fired power plant. Furthermore, the reported 52 transmission projects total more than US$3 billion in investment. This increases the requirement for infrastructure such as transmission poles, wires, insulators, suspension and tension hardware, bolted terminals, grounding devices, and surge protection. Transmission infrastructure provides an electrical link between generation facilities and important consuming centers. The transmission projects evacuate electricity from new power plants, increase transmission capacity, reduce network congestion, improve system reliability, and strengthen the SEIN.

    Bolted terminals provide secure, dependable, and long-lasting connections for solar, wind, and transmission installations. They offer a secure, low-resistance, and long-lasting electrical and mechanical joint in adverse environmental conditions. Terminals, such as mechanical lugs and splices, link big wires to switchgear, transformers, combiner boxes, and bus bars. This ensures a solid connection, lowering electrical resistance and heat generation. Bolted terminals are intended to transport currents for large-scale power generation. The terminals must withstand dynamic loads such as wind, vibration, and thermal expansion. The terminals are made of corrosion-resistant materials that are suitable with both copper and aluminum conductors, preventing galvanic corrosion.
