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:

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