Product Introduction

Overview:

The GTXGN-12 solid insulated ring main unit is a new generation of environmentally friendly solid insulated ring main switchgear independently developed by our company. It mainly consists of three functional units: the V unit (circuit breaker unit), the C unit (load switch), and the F unit (combination unit). Each unit can be used individually or freely expanded. The structure is divided into an intelligent control instrument chamber, an operating mechanism, and the primary section. The instrument chamber can be equipped with a microcomputer protection controller. The operating mechanism features a specialized spring-operated mechanism, and the primary section uses APG automatic gel technology, which fully encapsulates the isolation switch and arc extinguishing chamber in epoxy resin. It also includes specialized connectors and busbar insulation.
