The Necessity Of Strengthening The Supervision Of Power Fittings

Recent national spot check data shows that products transmission line hardware failed multiple tests, including hot-dip galvanized layer thickness, breaking load, gripping force, DC resistance, and twisted-pair gripping force of the wire clamps. The failure rate of products electrical transmission line hardware fittings in the spot checks reached approximately 3.2%.

This indicates that factory inspection and product certification alone cannot completely eliminate the risk of substandard products hardware fittings for transmission lines.

In the production stage of products aerial electrical fitting, monitoring of key technical parameters such as galvanizing, corrosion protection, and structural strength should be strengthened. In the installation stage of products power line hardware, batch tracking of materials, on-site connection status testing, and operational life analysis should be strengthened. Enhanced supervision will help improve the reliability of products overhead line fittings throughout their entire life cycle.
