The parts subjected to normal wear and agingneed to be serviced for ensuring full reliability of the operations. These parts may be mechanical components or electrical components. The interval at which the maintenance should be carried out depends upon the following factors: 1. The number of short-circuit interruptions 2. The switching frequency 3. The actual service time The actual conditions of use in terms of the frequency of operations, environment and severity of switching duty vary so much that it is impossible for the manufacturer to give detailed guidelines to the user concerning the frequency of maintenance.

    High Hardness. You can prevent a lot of electrical switchgear failures just by having sufficient hardness in your components. A switchgear component with good mechanical properties will hold up to the continual engaging and disengaging of the switchgear relay. Good Permeability. You want strong electrical properties, which means you want high permeability because it relates to fast response for both engagement and disengagement. Low Resistance. Resistance in electrical applications leads to heat accumulation – both a performance issue and a safety issue. Good alloying systems available with powder metal can deliver low-resistivity parts for electrical switchgear suppliers. Corrosion Resistance. Corrosion is a necessary consideration in electrical equipment design; fortunately you can do a lot to limit it. Corrosion is costly, requiring repairs and replacements earlier than you’d like.
