JDT-27.5

JDT-27.5 is a professional single-phase oil-immersed voltage transformer for 27.5kV railway traction power supply systems. Compliant with IEC and GB standards, this outdoor potential transformer is widely used in railway substations for accurate voltage monitoring, energy metering and relay protection.
Featuring premium insulation structure and high-purity insulating oil, the JDT-27.5 ensures reliable insulation and heat dissipation. The low-loss silicon steel core guarantees stable transformation ratio and high measurement accuracy, resisting voltage fluctuations and electromagnetic interference in railway power supply environments.
Adopting a fully sealed integrated structure, this 27.5kV voltage transformer avoids oil leakage, moisture and dust ingress. The high-strength anti-corrosion porcelain sleeve enables stable operation in complex outdoor environments along railway lines, including strong wind, low temperature and pollution conditions.
With optimized winding and balanced insulation design, the JDT-27.5 has strong overload capacity and low operating noise. It features a compact structure, long service life and low maintenance, effectively cutting operational costs for railway power supply projects.
Specially designed for 27.5kV railway power grid construction, the JDT-27.5 voltage transformer offers high precision and stable performance. We provide factory direct supply, complete certifications and reliable after-sales service for global railway power engineering projects.
