LV Oil Transformer Series

For high efficiency and safety, CIC’s low-voltage oil-immersed transformers are made with high-permeability silicon steel cores and insulating oil of a high ignition point.

About the Product

These LV oil-type transformers are widely used in power supplies for lighting, factory motors, and other equipment. Another common application of these transformers can be found in temporary power solutions for construction sites.

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

Cores made with high-permeability cold-rolled grain-oriented silicon steel sheets (CRGO), together with high-conductivity windings, make for low-loss, low-noise, and high-efficiency performance.
Insulating oil with high dielectric strength, chemical stability, and thermal conductivity.
Stringent pre-delivery testing to ensure quality.

Non-Ventilated Resin-Encapsulated Transformers (H-Class Insulation)
ET Series
Non-Ventilated Resin-Encapsulated Transformers (with H-Class insulation) are characterized by a reduced noise level compared to ordinary dry-type or cast-resin transformers. Compact and installable in a number of different ways, these transformers are furthermore self-extinguishing. With a durable IP20 enclosure, these transformers come in Regular Type and "Silent" Type, for the lowest sound levels. Optional accessories include protective devices for overload and over-temperature protection. SPD for protection against lightning is also available.
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.
Medium-Voltage Oil-Immersed Transformers
MV Oil Transformer Series
CIC’s medium-voltage oil-immersed transformers, characterized by high efficiency and safety, are made with high-permeability silicon steel cores, and insulating oil of a high ignition point.
Pad-Mounted Transformers
OSA Series (Padmount)
CIC Pad-Mounted Transformers have been used by the Taiwan Power Company for over 25 years. These products, well-received in numerous countries, are type-tested by CIC's internationally-accredited testing laboratory.
Pole-Mounted Transformers
Pole-Mounted Transformer Series
Made with premium-grade copper wire and insulation oil, these pole-mounted transformers can be specially designed or configured to meet the requirements of power companies in most countries. Every effort is made to ensure customer satisfaction.
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.
