Product Description


1 Brief introduction
HXGT18(HXGN26)-12(L) Box type AC metal-clad Switchgear(RMU for shorts) is designed and developed by our company, which introduce into foreign advance technique and accord with national power supply requirement. After the type test and long trial operation check, the product performance index has reached IEC298 AC Metal-clad switchgear and GB3906 3-35KV AC Metal-clad switchgear, and meet the reliable fault prevention operation function of the two parts requirements, protection degree reached IP2X. This product features small bulk, light weight, easy operation, safety operation, easy maintenance, etc. It is a newly type of high voltage switchgear suitable formunicipal power net improvement and reconstruction.Switchgear Basic Technical Parameters
