As a critical downhole conveying equipment, the ESP variable frequency drive system faces three major challenges: long-cable transmission, choke signal interference, and harsh on-site operating environments. Nancal Electric's medium voltage drives, based on cell series multi-level topology, with long-cable adaptive control as the core and choke system compatibility as a distinctive feature, effectively address industry pain points through deep integration of hardware optimization and software algorithms.
Nancal Electric has officially launched its comprehensive, one-stop retrofit and upgrade service for medium voltage drives. Power cells and control systems can be easily renewed, delivering a major reliability upgrade, with both on-site and factory remanufacturing options. Our solutions help extend equipment service life and improve operational efficiency.
Nancal Electric supplies medium voltage drives for the newly commissioned Unit 3 at PipeChina's Guangzhou Compressor Station, continuing its long‑term role as a core localization partner for China's unified national pipeline network.
Nancal Electric completes full localization of eight imported RCP drives at Haiyang Nuclear Phase I, eliminating unplanned shutdowns and enhancing operational reliability with a "4-operation, 1-standby" drive system configuration.
2025 was a year of deep technical cultivation and steady advancement for Nancal Electric. Guided by the spirit of engineers, we drove continuous innovation in power electronics and electrical drives, delivering reliable products and solutions to help build a clean, low-carbon, safe, and efficient energy ecosystem.
Recently, following independent application, recommendation, expert evaluation, and public announcement in accordance with government guidelines, Shanghai Nancal Electric Co., Ltd. has been officially granted the title of 2023 Shanghai Science and Technology “Little Giant” Enterprise.
