Medium-Voltage (MV) Voltage Transformers / Potential Transformers 36 kV
Indoor & Outdoor Epoxy Resin Cast VT Instrument Transformers for Metering Units and More
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.

Single-Pole Voltage Transformers (Potential Transformers), or Three-Phase VT (PT) + GVT (GPT)
EPF-10CE, EPF-20SK, EPF-20SL, EPF-20SNE, EPF-20DZE, EPF-30DE
Single-pole voltage transformers in this indoor medium-voltage range are epoxy-resin-cast potential transformers designed for 12 kV, 24 kV, and 36 kV power systems. These instrument transformers operate with measuring and monitoring instruments for power system analysis and supervision or in conjunction with protective relays to support system safety and reliability. Selected models can be equipped with a primary-side fuse assembly, and certain models offering a rated thermal burden of 1000 VA or higher may also serve as a power source for circuit breaker operation, functioning as control power transformers (CPT), control transformers (CTR), or industrial control transformers in switchgear and machine tool applications.
Outdoor-Type Voltage Transformers (Potential Transformers) for Revenue Metering
VPF Series
Outdoor voltage transformers in the VPF Series are medium-voltage (MV) potential transformers designed for revenue metering applications. As part of a Metering Outfit (MOF), these 15.5–36.5 kV instrument transformers are cast in Araldite® UV-resistant cycloaliphatic epoxy resin and are suitable for long-term outdoor service in harsh environments, including solar ultraviolet radiation, salt fog, high temperature, and high humidity.
36 kV Epoxy-Cast Voltage Transformers (Potential Transformers)
EPF-30SA, EPF-30SB
Indoor-use voltage transformers (potential transformers) for 36 kV (max.) power systems. IEC type testing & environmental testing (-45℃~+65℃). The choice of major corporations of numerous countries. Insulated with Araldite® epoxy resin. Superior moisture resistance.
36 kV Metal-Clad Voltage Transformer (Potential Transformer) for Indoor Application
EPF-30SE
Intended for the switchgear panels of a 36 kV power system, this single-pole epoxy-cast voltage transformer (potential transformer) for indoor application is covered with an aluminum box. The grounded aluminum box for shielding reduces the installation space requirement.
