Outdoor current transformer TPO
Transformers are designed for insulation voltages up to 40.5 kV
This family of current transformers are dedicated for high demanding applications such as substations.
The TPO family of transformers are cast in hydrophobic cycloaliphatic epoxy resine (HCEP), capable of withstanding outdoor environmental conditions. The HCEP material offers superior arc track, ozone, and ultraviolet-resistive properties while maintaining physical strength. The hydrophobic surface properties of HCEP ensure highly reliable performance in wet or humid environments.
Product scope
