Surge arresters are not glamorous equipment. They sit quietly on overhead lines, in substations, and beside switchgear, doing nothing until the moment they're needed most.

In the world of electrical power systems, zinc oxide (ZnO) surge arresters are the unsung heroes. When a lightning strike reaches the line, or a switching operation sends a voltage spike racing through the system, it's the surge arrester that steps in, clamping that overvoltage and diverting the energy safely to ground.

The KEMA certification is a significant milestone for HAIVO Electric, underscoring its commitment to engineering excellence, product safety, and reliability. The comprehensive test protocol evaluated the arresters' critical performance parameters under simulated real-world conditions, including designated discharge current tests, residual voltage tests, long-duration current impulse tests, and thermal stability assessments.

Zinc oxide is very important in surge arrester design. It has resistance that changes a lot, which helps stop dangerous voltage spikes. The material reacts fast to surges and gives strong protection. Zinc oxide surge arrester blocks use special sealing methods. These methods make them last longer.
