00:00Why this worker is smashing glass balls with a wrench at a 300-foot electric tower.
00:03Firstly, this hazardous task demands nerves of steel.
00:07So, these glass balls serve as high-voltage insulators,
00:09crucial for preventing electrical connections between wires and crossbars.
00:13As made from ceramic with a disc-shaped design,
00:15rain won't compromise insulation.
00:17And replacements are essential to prevent damaged insulators from causing short circuits.
00:21But smashing and replacing insulators is the most efficient method
00:24to maintain safety and functionality.
