Power transformer

Product catalog summary

Product Overview: This document provides technical specifications for oil-type power transformers designed for road lighting applications. The transformers are compliant with NFC 17-200 standards and are available in various power ratings.

Electrical Specifications: The transformers have power ratings ranging from 100 kVA to 1250 kVA. They feature iron and copper losses, no-load current, efficiency at different power factors, voltage impedance, and voltage drop specifications. The transformers are designed to operate at a primary voltage of 20 kV and a secondary voltage of 5.5 kV.

Electrical Characteristics: The insulation class ranges from 7.2 kV to 24 kV. Primary windings are compatible with various insulating voltages, and secondary windings offer 3200 V and 5500 V neutral outputs. Standard and specific coupling options are available, including three-phase and tri-mono transformers.

Connections and Accessories: Primary and secondary connections use plug-in bushing bars. Standard accessories include filling taps, draining valves, rollers, earthing terminals, and lifting lugs. Optional accessories include tertiary scrolls, secondary plug-in bushing bars, terminal locking, and oil retention pans.

Construction: The core is made of crystal-oriented steel with carlite insulation, and windings are made of copper or aluminum. The transformers are cooled using the ONAN method and are designed for indoor use with a full filling tank.

Standards and Tests: The transformers conform to NFC 17200, NFC 52100, and CEI 76 standards. Routine tests are conducted on each transformer, with specific tests available upon request.

Dimensions and Weight: Detailed dimensions and weights are provided for each power rating, including length, width, height, and total weight. Oil weight and roller specifications are also included.

Certification: AUGIER is ISO 9001 certified since 1995 and also produces dry-type transformers.
