Under Oil

Under-oil distribution arresters are designed and tested to meet or exceed the application requirements of IEEE C62.11, ensuring they provide top-tier protection for oil-filled electrical equipment. Available for system voltages from 2.5 to 36 kV, these arresters are essential for maintaining the integrity and performance of transformers and other critical apparatus within power systems. By operating effectively submerged in insulating oil, they preserve the dielectric strength of the oil, preventing breakdowns and extending equipment life. Ideal for use in substations and demanding settings, under-oil IEEE arresters enhance the reliability and safety of electrical infrastructure, ensuring stable and uninterrupted power delivery.
