JDT-55
Equipped with premium insulation structure and high-purity insulating oil, the JDT-55 delivers reliable insulation performance and stable heat dissipation. The low-loss silicon steel core ensures accurate transformation ratio and high measurement precision, effectively resisting voltage fluctuation and electromagnetic interference in railway power supply environments.
Featuring a fully sealed integrated structure, this 55kV voltage transformer prevents oil leakage, moisture and dust intrusion. The high-strength anti-corrosion porcelain sleeve adapts to complex outdoor conditions such as strong wind, low temperature and industrial pollution along railway lines for stable all-weather operation.
With optimized winding layout and balanced insulation design, the JDT-55 has strong overload capacity and low operating noise. It features compact structure, long service life and low maintenance, effectively reducing operational costs for railway power supply projects.
As dedicated core equipment for 55kV railway power grid construction, the JDT-55 voltage transformer provides high precision and reliable performance. We offer factory direct supply, complete certifications and professional after-sales service for global railway power engineering projects.
