Established in 2011, our facility is an excellent and reliable power equipment manufacturer. We mainly develop and produce oil-immersed transformers, dry-type transformers, box-type substations, high-voltage switches, and medium and low voltage complete sets of equipment. The equipment advocates energy saving, intelligence, informatization, and mechanization. With 71 utility model patents and 15 invention patents, our products are sold to the Middle East, North America, South America, Europe, Southeast Asia, Africa, and other regions, covering more than 40 countries.

The new generation of GIS is equipped with a spring operated mechanism. Its arc extinguishing chamber adopts the semi-self energized interrupting principle, adapting gas blast pressure to the breaking current. The equipment has passed all required type tests and national-level appraisals, utilizing dual gas chambers to extinguish the arc by way of self-energization.

The GIS features a three-pole-in-one enclosure. Main components include the Circuit Breaker (CB), three-position Disconnector/Earthing Switch (DES), Current Transformer (CT), and Voltage Transformer (VT). Conductors for the CB are arranged in a straight line, while other components follow a regular triangle arrangement in the enclosure. Spring contacts ensure stable transit connection between conductors.
