Smart Medium Voltage Complete Switchgear
JGNIS1.0-12 SF6 gas insulated metal enclosed switchgear
JGNIS1.0-12 gas insulated metal enclosed switchgear (C-GIS) is suitable for systems with a rated voltage of 12kV and a rated current of 1250A~4000A. It is the latest indoor high-voltage switchgear developed by Jinguan Group, which integrates switches and key components into a sealed stainless steel gas box to ensure that no live parts are exposed. It not only has a compact structure, but also achieves full insulation, long service life, and maintenance free characteristics. It is compact in size, safe and reliable, and can operate stably even in harsh environments. Its characteristics include high safety, climate independence, easy installation, minimal maintenance, space saving, no exposed live parts, long-term operation in harsh environments, and flexible busbar expansion.

Product Highlights
Provides interfaces for future intelligent management of the power distribution network, demonstrating foresight.
Adopts an integrated design, integrating the main components into a sealed gas box, making it compact and suitable for space-constrained locations.
Modular interchangeability, with uniform height and depth for handcarts (circuit breakers/transformers, etc.) of the same specifications, supporting position locking and anti-misoperation interlocking.
It records various abnormal events, such as power outages, power restoration, voltage exceeding limits, current overload, power exceeding limits, power factor exceeding limits, meter failure, and communication interruption, and reports them to the backend system.
Complete solutions and convenient combinations are available, allowing for mixed PC and MCC configurations.
