Trench Reactors Product Leaflet

About this manual

Trench is a world leader in the design and manufacture of air‑core, dry‑type power reactors for utility and industrial use. The brochure outlines the design features, such as epoxy‑impregnated fiberglass construction, zero radial voltage stress, and a service life exceeding 30 years, as well as compliance with ANSV/IEEE and IEC standards.

The document details a wide range of reactor types—series, buffer, filter, shunt, thyristor‑controlled, smoothing, and specialty iron‑core or oil‑type reactors—along with typical applications like fault‑current reduction, load balancing, harmonic filtering, and HVDC smoothing. Ordering data, enclosure options, and pedestal designs are also provided.
