Dry Type Transformer

Transformers is an essential part of electrical power system used to transform voltage from primary to secondary (step down) or from secondary to primary (step up). There are two main types of transformers: Oil-type transformers and dry type transformers.

While oil type transformer employ oil for cooling and insulation, dry type transformers employ resin as insulation. The resin insulator provides constant insulation over the transformer's service life, resulting in less maintenance requirement and better reliability. Additionally, dry type transformer also fit into smaller footprints.

At Adidaya, we distribute quality dry-type transformer from ABB. Our expert engineers can help in design, procurement and installation of dry type transformers for your project.

Features of Products

  • Safe, fire self-extinguishing, fireproof, low noise level, pollution-free; available at load center.
  • Made up of all-copper foil, the H&L voltage windings have high short circuit withstand capabilities, high lightning impulse withstand capability and high reliability.
  • The H&L voltage windings are molded with epoxy resin on high vacuum. The partial discharge is lower. Air channels can be installed. Humid-resistant and high heat dissipating ability. It is able to run normally under the relative humidity of 100%. Rated capacity can increase 40% as air-cooling.
  • Convenient installation; easy maintenance; low losses and general operation cost.
  • Temperature display and controlling system, which resists the interference from electric and magnetic field, is installed on windings to ensure safe operation of transformer. Computer interface can be fixed so that it can be controlled and monitored remotely.
  • It can be equipped with protection enclosure and connection busbar, which enables it to be used both indoors and outdoors. Indoor built-up structures may be immune to the limitation of the doorframes in the installation location. Connection busbar can be directly connected to the busbar of switchgear, which is really convenient.
