Global renewable‑energy construction boom drives huge demand for matching overhead power fittings. In recent months, Chinese manufacturers have upgraded processing details for P‑Type Hanging Plate (double‑plate parallel clevis), aiming at overseas solar and wind‑farm overhead collection‑line projects. Optimized products have obtained positive feedback from multiple Latin‑American and Middle‑East new‑energy EPC buyers, marking further expansion of Chinese power‑fitting enterprises within the global new‑energy supporting supply chain
Different from conventional urban and rural distribution‑grid projects, overhead lines of photovoltaic and wind‑power stations run under complex working conditions. Wind vibration occurs frequently in open‑air wind‑farm zones, putting forward higher requirements for anti‑fatigue property of connecting hardware. R&D technicians optimized blanking edge finishing and hole‑position tolerance control for P‑Type Hanging Plate series. Comprehensive deburring eliminates stress‑concentration points on steel‑plate cutting edges. Dual‑plate force‑sharing structural advantages are fully exerted, so tensile load can be evenly distributed on two steel sheets instead of concentrating on single position, lowering deformation risk caused by long‑time cyclic vibration
The whole product portfolio covers seven mainstream models ranging from P‑0770 to P‑32120, with nominal breaking load from 70 kN to 320 kN. Each model's dimension parameters including plate clearance C, bolt specification M and hole‑center distance H strictly follow domestic power‑fitting standards, meanwhile retaining high interchangeability for international‑market matching hardware. Raw‑material incoming inspection is implemented for every batch carbon‑steel plate. Chemical composition and mechanical‑strength indicators must pass verification before putting into production. Hot‑dip galvanizing procedure strictly manages zinc‑bath temperature and dipping cycle, preventing zinc lump and local bare‑spot defects. Thread sections are protected during galvanizing to guarantee smooth bolt assembly for field workers
For cross‑border new‑energy projects, apart from product mechanical performance, purchasers attach great importance to certification documents, third‑party test support and flexible customized service. The factory holds ISO9001 quality‑management‑system certification. Upon client requirement, third‑party mechanical‑performance test reports can be issued for tender submission. When facing special‑scenario demands such as extra‑heavy corrosion environment or non‑standard connection dimension, engineering team can launch ODM custom development, adjusting plate thickness, hole spacing and outer outline according to technical sheets or sample drawings provided by overseas customers
In terms of international trade practice, the enterprise supports multiple trade terms including FOB, CFR and CIF. Technical datasheets, 2D drawings and MTC material certificates can be provided in English version. In the recent Latin‑America photovoltaic‑station supporting project, over 9 600 sets of optimized P‑Type hanging plates were adopted for suspension‑insulator‑string connection of overhead collection circuits. After one‑year field operation feedback, no corrosion or abnormal deformation happened under local strong‑wind climate.
Industry analysts point out that global new‑energy infrastructure keeps expanding, and supporting overhead‑line hardware will maintain steady market demand. Chinese power‑fitting manufacturers possess complete industrial‑chain advantages. By continuously optimizing product craft and strengthening international‑standard documentation service, domestic enterprises can further enhance competitiveness in overseas new‑energy projects, realizing transformation from simple component export to comprehensive technical supporting service for global energy‑construction clients
At present, P‑Type hanging‑plate products have been exported to Southeast Asia, Middle East and East‑Africa regions, accumulating rich practical experience for tropical high‑humidity and coastal corrosive operating environments. Industry insiders believe that as more developing countries speed up power‑infrastructure construction, cost‑effective, high‑reliability Chinese overhead‑line fittings will gain larger market share in global power‑equipment supply chains
