"Anti-aging" must be translated as anti-aging.  The glass insulator addresses core insulation issues through high breakdown strength and excellent aging resistance, while its unique "zero-value self-explosion" mechanism makes potential faults instantly visible. This perfect combination of "high performance" and "easy maintenance" is a key, irreplaceable feature in power systems.
