Driven by global grid‑resilience investment tide, many Latin‑American countries kick off large‑scale renewal of aging overhead distribution networks in 2026. Decades‑old overhead lines suffer metal fatigue, component loosening under frequent tropical storm and strong‑wind weather. Local power utilities replace massive volume of old connection hardware to lower outage risk triggered by extreme weather. Recently, a large consignment of P‑Type Hanging Plate (Parallel Clevis Type‑P) completed all pre‑shipment inspections and will be transported to multiple grid‑renewal sites across Latin‑America. This batch combines standard models P‑1290, P‑16100 and partial reinforced‑thickness customized units, totalling 18 600 sets, deployed for 35kV‑110kV overhead‑line insulator‑string connection in renewal projects
Different from brand‑new green‑field power construction, aging‑line renovation puts forward special requirements for connecting fittings. Many on‑site reserved mounting dimensions inherit from old‑generation local hardware. Simply adopting off‑the‑shelf standard parts may produce clearance deviation after installation, generating additional shear stress under storm‑induced line sway. Such hidden defects will gradually expand after long‑term wind vibration and further threaten grid operation safety. Our technical team carried out parameter matching according to as‑built drawing samples provided by the Latin‑American EPC contractor. For partial special sections, plate‑thickness‑enhanced P‑type hanging plates are adopted without changing original hole‑center distance and plate‑gap dimension, reusing existing insulators and link hardware to control overall project investment
All products follow unified production workflow including CNC blanking, multi‑pass deburring and hot‑dip galvanizing. Considering frequent tropical rain‑storm environment, zinc‑coating thickness is strictly implemented according to coastal atmospheric anti‑corrosion requirement. Each production lot finishes sampling mechanical destructive tension test. Test data, dimension inspection record and English‑version material test certificate are attached for project filing and local regulatory audit.
In the past, some regional renovation projects purchased low‑cost fittings without full‑set test documentation. After short‑term field operation, hardware deformation and coating peeling occurred during storm seasons, causing repeated power outages. Local power departments now raise procurement thresholds for renewal‑project hardware, emphasizing traceable mechanical performance and complete technical documentation rather than focusing merely on unit price.
Manufacturer's overseas business director commented that aging‑grid renewal occupies rising proportion among overseas orders in 2026, not only demanding qualified mechanical indicators, but also high compatibility with legacy‑generation on‑site hardware. Apart from Latin‑America, similar renewal demands keep rising across Southeast‑Asia and Central‑Asia market人民日报. Chinese power‑fitting suppliers shall deepen understanding of local legacy‑grid actual conditions, not only supplying stock items but also offering targeted dimension‑matching consulting service.
Industry observers point out that as more emerging economies prioritize grid‑resilience construction, renovation‑oriented customized connection hardware will become an important growth track for China's power‑hardware export business.
