Analysis Of The Tightness Of High-voltage Disconnect Switch Leads

When the lead wire is too slack, the conductor is prone to swinging or vibration during the installation or operation of high voltage electrical isolator. Long-term vibration may lead to poor contact at the connection point, uneven mechanical stress on the insulator, or even metal fatigue or lead wire damage. isolator high voltage faults are often related to mechanism corrosion, mechanism jamming, and improper debugging.

Conversely, excessively tight lead wires also pose risks. Tight conductors may apply excessive tension to the connection points during installation, causing bolts and terminals to be overloaded. This is similar to the situation in electrical equipment where overly tight terminal connections cause poor contact or terminal damage.
