Our Drop‑Out Fuse Cutout is a reliable line protection device combining a fault‑clearing fuse tube with a porcelain insulator body. Designed for overhead distribution and transmission networks, it safely isolates faulted sections by “dropping out” the fuse element under over‑current conditions. The robust porcelain housing provides mechanical strength and weather resistance, while the modular fuse tube allows rapid replacement after operation.

Our Surge Arrester series provides reliable over‑voltage protection for overhead lines, substations, and industrial installations. It uses a metal oxide varistor (MOV) element to clamp lightning and switching transients, protecting transformers, switchgear, and sensitive equipment. Available in porcelain‑insulated or polymer‑housing designs, each arrester meets IEC 60099‑4 standards and undergoes rigorous impulse and thermal testing to ensure durability in the harshest environments.
