Preventing Substandard Electrical Fittings From Entering The Market And Controlling Quality From The Source.

Strict qualification audits are required for the overhead power line hardware supply chain. Suppliers must pass material composition testing and strength testing. During the procurement process, any transmission line hardware that has not provided an authoritative testing report will be rejected.

An incoming inspection sampling system is implemented. Dimensional and physical properties are randomly sampled from each batch of goods for testing. The inspection team consists of engineers with many years of experience. Any non-compliant electrical transmission line hardware fittings will be returned promptly.

Transparent records are maintained throughout warehousing and distribution. For each batch, hardware fittings for transmission lines retains the source, test report, and certificate of conformity. A tracking system covers the entire process from supplier shipment to customer receipt.
