Why would I want to have zinc sleeves added to the pins of my toughened glass bell suspension insulators?

When a sleeve composed of zinc in adherence to the IEC/ANSI standards for purity is applied and bonded to the pin, it acts as a sacrificial anode. A bonding surface of at least 80% ensures there are no gaps and corona discharges are avoided. The zinc sleeve now offers an even lower potential than the forged steel pin therefore preventing the removal of ions which leads to electrolytic corrosion from this critical strength component.
