Low-Voltage Dry-Type Transformers

DTH Series

LV Dry-Type Transformers, made with high-permeability cold-rolled grain-oriented silicon steel sheets (CRGO) and H-Class insulating materials, are self-extinguishing and characterized by excellent dissipation of heat, high efficiency, low noise, easy installation, and low maintenance.

About the Product

CIC’s DTH Series LV Dry-Type Transformers, for voltage conversion in low-voltage systems, are made with high-permeability cold-rolled grain-oriented silicon steel sheets (CRGO) and H-Class insulating materials. Characteristics of these transformers include excellent dissipation of heat, tight construction, their self-extinguishing property, high efficiency, low noise, easy installation, and low maintenance. Common applications of these transformers can be found in factories, commercial buildings, and public constructions. To ensure product quality, safety, and durability, all units undergo pre-delivery testing by an electricity laboratory accredited by TAF, a member of the ILAC.
