Indoor and Outdoor 36 kV Voltage Transformers
Indoor and Outdoor 36 kV Voltage Transformers

36 kV Voltage Transformers (VT) by CIC include both indoor and outdoor potential transformers (PT). The series features single-pole resin-cast voltage transformers, capable of being combined into three-phase voltage transformer and Grounding Potential Transformer sets, alongside metal-clad-for-shielding resin-cast voltage transformers. Additionally, there are models specifically designed for power billing Metering Outfit (MOF), renowned for their exceptional UV resistance and enduring resilience, trusted by power companies across countries for over two decades.

CIC's epoxy resin-cast voltage transformers utilize Huntsman's (formerly Ciba-Geigy in Switzerland) internationally acclaimed Araldite® epoxy resin. The outdoor models are meticulously crafted with UV-resistant cycloaliphatic epoxy resin, ensuring unwavering quality. Type tests and routine tests for CIC's voltage transformers are executed at CIC's Advanced Electricity Lab, accredited by TAF, a member of ILAC. With decades of experience, CIC not only manufactures voltage transformers but also offers customization and ODM/OEM services. Widely adopted by power utilities, major projects, and construction companies worldwide, CIC's voltage transformers play a crucial role in metering and distribution projects.

    EPF-10CE, EPF-10DE, EPF-20SK, EPF-20SL, EPF-30DE

    Voltage transformers from this series are indoor medium-voltage single-phase epoxy-resin-cast potential transformers suitable for 12kV, 24kV, and 36kV power systems. They are used in conjunction with measuring instruments for system monitoring and analysis or in combination with protective relays. Specific models can be equipped with a combination fuse assembly on the primary side. Additionally, models with a maximum thermal burden of 1000 VA can also function as a power source for circuit breaker operation, meaning they can serve as "control power transformers" or "control transformers," also known as CPT or CTR, or "industrial control transformers" or "machine tool transformers."
