Three Phase High Voltage Outdoor 110KV Power oil-immersed type voltage transformer
Model and meaning
Product Overview
Designed for 110kV, 50Hz neutral point effectively grounded systems, the JDC6-110 voltage transformer adopts a single-phase three winding series insulation design. This sophisticated structure empowers it to accurately measure voltage and energy while providing essential support for relay protection systems, ensuring grid stability and safety.
This voltage transformer excels with outstanding excitation characteristics, demonstrating remarkable anti-resonance capabilities. Such features, combined with its reliable performance and user-friendly maintenance design, make it a preferred choice for electrical installations. The top-mounted stainless steel corrugated expander contributes to its fully sealed construction, safeguarding internal components from environmental elements.
For geographical adaptability, the JDC6-110W model is optimized for regions with an altitude of 1000 meters or lower, while the JDC6-110GYW variant extends this capability to areas up to 3000 meters above sea level. This differentiation allows for broader deployment across diverse terrains, ensuring consistent and efficient operation regardless of elevation challenges.
