Mechanical Properties And Appearance Inspection Analysis Of Power Fittings

Load-bearing capacity is a fundamental indicator for judging the condition of equipment. The destructive load of distribution line hardware should not be less than the nominal value. Regular tensile tests, compared with design parameters, can assess the remaining strength of components. The grip strength variation of the overhead line connectors suspension type and the tensile strength of the connecting parts both need to be quantitatively tested using professional instruments.

Accurately identifying the working status of power transmission equipment requires the comprehensive use of various technical means. Only by establishing a complete evaluation system, from appearance to internal performance, from electrical characteristics to mechanical strength, can reliable support be provided for the operation and maintenance decisions of overhead line hardware.

The condition of the equipment surface can reflect its operating status. Through inspection and observation, technicians can discover whether there is rust, deformation or mechanical damage to the overhead power line connectors. All overhead power line hardware surfaces should be treated with hot-dip galvanizing for corrosion protection. When the coating peels off over a large area, it indicates that the component is in an abnormal condition. Cracks or broken strands in wire clamps indicate that the stress at that location has exceeded the design limits.
