In mid-May, a batch of our high-quality composite insulator productscompleted all the factory quality inspections and packaging for shipment, and successfully set sail from Ningbo Port, heading for the Zambian market in Africa. The successful delivery of this order not only demonstrated the excellent quality of our Composite Insulators but also further expanded the African overseas power market territory, injecting high-quality domestic products into the local power grid infrastructure upgrade construction.
Quality is the core strength for the export of products. To ensure that the exported products fully adapt to the complex outdoor power grid operating environment in Zambia, and strictly comply with IEC and national standards GB/T 19519 industry standards, our company conducted a complete set of rigorous factory-specific performance tests for this batch of products. This time, multiple core key tests were focused on, including bending mechanical performance tests, one-minute alternating current wet endurance tests, and breakdown voltage tests, to comprehensively verify the mechanical bearing capacity and electrical insulation performance of the products.
Among them, the wet endurance test precisely simulates the outdoor rainy and humid conditions, verifying the insulation stability of the products under adverse environments; the breakdown voltage test strictly controls the electrical threshold to eliminate the risks of leakage and flashover, and the bending test effectively guarantees the structural stability of the product during line suspension operation. All products passed all tests, and all performance indicators met the standards, fully meeting the safety operation requirements of overseas high-voltage transmission lines.
After completing all quality inspections, appearance verification, and moisture-proof packaging, this batch of products were orderly completed for storage in warehouses, port customs declaration and loading operations. They have now officially set sail for Zambia. As a core component of the power grid, these composite insulators will be widely used in the construction of local transmission lines, leveraging their advantages of aging resistance, strong insulation, and high stability to help the local improve the stability and safety of the power grid supply.
In the future, our company will continue to adhere to strict quality control standards, refine high-quality products, and with reliable product strength and professional foreign trade services, provide high-quality Made-in-China products for global power infrastructure projects.
