ADVANTAGES OF CAST INSULATION CURRENT TRANSFORMERS:

• Lack of any maintenance throughout the entire period of operation
• Fireproof design
• Possibility of installation in any plane
• High loads for all accuracy classes
• Low partial discharge (PD)
• Resistance to aggressive environmental conditions
• The hydrophobic material exhibits excellent outdoor performance and also minimizes the possibility of arcing.
• No ozone depleting gases

Transformers meet the requirements of IEC, ANSI, IEEE, GOST standards.
