SYM6-GIS

GIS fully enclosed and insulated switchgear

Product Introduction

SYM6-GIS series fully insulated and fully enclosed ring main switch cabinet (referred to as "inflatable cabinet"), Also known as gas insulated switchgear, it is independently developed by our company by absorbing advanced technologies from both domestic and foreign sources New type of medium voltage ring main unit. This series of inflatable cabinets features a high-quality 3mm stainless steel casing for the air box. Stainless steel plates are laser cut into shape and automatically welded by advanced welding robots, Ensure the airtightness of the gas box. The SF6 gas filled in the gas box undergoes synchronous vacuum testing: grounding switch Vacuum circuit breakers and other switch moving parts, as well as busbars, are sealed in stainless steel gas boxes, The protection level of the gas box shell reaches IP67, and it is then inspected and controlled layer by layer by the quality inspection department until the product is completed.
