LV Cast Resin Dry Type Transformers (CRT)

Self-extinguishing low-voltage dry-type transformers, with coils cast in epoxy resin, for moisture-prone and polluted environments. Cores made with cold-rolled grain-oriented silicon steel sheets. Optional protective enclosures available for outdoor applications.

About the Product

In CIC’s low-voltage Cast Resin Dry Type Transformers (CRT), coils are cast in epoxy resin (Class F insulation). These transformers, with excellent insulation, are self-extinguishing and can be used in moisture-prone and polluted environments. Protective enclosures (optional) will enable outdoor applications of these transformers and offer additional protection against dust.

Examples of suitable applications include rapid transit systems, public transport stations, hospitals, residential and commercial buildings, and factories where significant pollution is present.

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) according to ISO/IEC 17025.

Product Features

  • High-permeability transformer cores made with cold-rolled grain-oriented silicon steel sheets (CRGO), together with tight windings of high conductivity, ensure low-noise and high-efficiency performance.
  • Self-extinguishing property, superior insulation, and excellent resistance to pollution and moisture—made possible by casting of the coils in epoxy resin.
  • For transformers with a rating of 25 kVA or above, there are cooling ducts within the coils (between primary and secondary windings) for enhanced dissipation of heat.
  • Optional protective enclosures (IP20) available.
  • Optional protective devices available for overload and over-temperature protection.
  • Custom requests and specifications available.
