Under Oil

Under-oil distribution arresters are designed and tested to meet or exceed the requirements of IEC 60099-4, ensuring top-tier performance and reliability. Available for system voltages from 2.5 to 36 kV, these arresters are specifically crafted to operate submerged in insulating oil. They play a crucial role in protecting transformers and other oil-filled electrical equipment from voltage surges caused by lightning strikes and switching surges. By maintaining the dielectric strength of the oil, under-oil arresters prevent breakdown and enhance the longevity and reliability of electrical systems. Ideal for power generation and distribution environments, these arresters are essential for safeguarding critical infrastructure against disruptive voltage spikes.
