Transformers and Autotransformers


          Transformers and Autotransformers

Monophase and threephase: from 50 VA to 80 kVA

       
 
Technical Characteristics

Our monophase and threephase transformers and autotransformers are designed to meet the following priority requirements:

bullet Insulation class E for overtemperature max 75°C with ambient temperature of 40°C max.
bullet The insulation is subjected to the dielectric strength test: 4 kV between the primary and secondary windings and 2.5 kV between these windings and the ground.
bullet The listed power refer to continuous working with power factor = 1 and frequency 50-60 Hz.
bullet Fullpower data always refer to the maximum voltage.
bullet For transformers having many secondary voltages has to be specified the drawing power on every voltage.
bullet The terminal boards eliminate the risk of accidental contact and are made of self-extinguishing material.
bullet COMPLIANCE WITH THE STANDARDS CEI 14-4/8

          Insulation Transformers

Monophase: from 500 VA to 30 kVA - Trimonophase: from 3 kVA to 40 kVA - Threephase: from 3 kVA to 75 kVA

       
TS-8  10 kVA
