Protection Devices
Our product range
Reliable protection is essential for safe and uninterrupted transformer operation. Our carefully selected range of devices includes arresters, fuses, and Buchholz relays – all designed to detect, isolate, and mitigate electrical faults before they lead to equipment failure or costly downtime. From managing transient overvoltages to sensing gas accumulation from internal faults, these components provide early warning and rapid response, helping to extend asset life and maintain grid stability.
By partnering with trusted manufacturers, Weidmann ensures each product meets the highest standards of quality, performance, and reliability for critical applications.
Arresters, Bushings, and Wildlife Guards
Weidmann, in partnership with Celeco®, offers a targeted selection of high-quality surge arresters, bushings, wildlife guards, and accessories for power and distribution transformers. Celeco’s polymer surge arresters feature a non-fragmented design and premium silicone rubber housings, providing reliable protection against overvoltages in transformers, reclosers, and capacitor banks.
The portfolio includes polymer and porcelain bushings for both high and low voltage applications, as well as wildlife guards designed to reduce outages and protect endangered species. An innovative drip guard for fuse holders prevents fluid contamination of nearby components, supporting both safety and equipment longevity.
These products are exclusively available through Weidmann Electrical Technology in the USA, Canada, and South America. To confirm availability, please contact us via the link below.
