Stable and safe high-voltage switching equipment is the core guarantee for power plant, urban grid and data center operation. 10kV Isolated High Voltage Handcart is an integrated mobile switch unit integrating circuit breaker, mutual inductor and isolation components. Shanghai Zikai Electric Co., Ltd. (ZIKAI) has over 10 years of high-voltage equipment R&D and production experience, shortlisted supplier of State Grid.
10kV Isolated High Voltage Handcart is a movable integrated high-voltage equipment independently developed by ZIKAI. It integrates vacuum circuit breaker, isolating switch, earthing switch, optional current and voltage transformers. The whole set adopts high-strength insulating structure, which forms reliable physical isolation between operators and live charged parts to avoid electric shock risks during maintenance. Equipped with guide rail moving trolley and locking device, it can be pushed and pulled flexibly inside the switch cabinet, convenient for equipment overhaul and replacement. All electrical components pass strict screening and testing, supporting automatic control and remote monitoring, widely matched with all kinds of 10kV high voltage switchgear.
