Low-Voltage Oil-Immersed Transformers

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.
  • Custom requests and specifications available.
