Distribution Transformer

A Distribution Transformer is a device used in the power transmission of electric energy. The transmission current is AC. It is commonly used to increase or decrease the supply voltage without a change in the frequency of AC between circuits. The transformer works on basic principles of electromagnetic induction and mutual induction. It is also introduced as a typical form of an isolation transformer. The basic function of this Distribution Transformer is to modify the high voltage to the standard output.

• High performance with high efficiency, according to the needs and strategies to reduce system losses and save energy of each customer.
• Step-lap-type magnetic core, resulting in optimization of the noise level, better natural anchoring of the set to withstand short circuit stresses, and low excitation current.
• Conductors covered with thermostabilized insulating paper class E (120^oC), whose special characteristic is to delay the regular aging process of the transformer;
• External coatings for the harshest environments, upon specification;

• Oil level, temperature and pressure controlled by a single protection accessory (RIS - Integrated Safety Detector).

• Option of ecologically correct (natural or synthetic ester-based, biodegradable) insulation fluid, presenting high safety level of flammability with fire point twice as high as the one of mineral oil and self-extinguishing properties, thus reducing the risk of fire propagation.
