Cubicle Fixed Indoor AC Metal-Clad |
Product Description
Cubicle Fixed Indoor AC Metal-clad Ring Main Unit Switchgear (here in after shorted as "RMU") is a latest version of high voltage equipment by absorbing and digesting advanced technology in domestic and abroad. It is researched an designed an designed by our company itself for satisfying requirements of our country' s power supply circles, specially suitable for municipal power supply net of improvement and reconstruction. After a model approval test and a long-term running test, this product is certified to meet IEC298 standard Alternative Current Metal-clad Switchgear and Control-gear form 1kV up to 52kV, including 52kVand meet the regulations and specifications of reliable anti-error operation measures issued by the former State Mechanical Industry Ministry and the former State Electricity Industry Ministry. Protection level of the product comes up to IP2X. It features small volume, light-weight, easy operation, small operative force, safety, easy maintenance, stable and reliable quality, free of fire disaster or explosion disaster, close to wall installation, small area occupied, etc. And if required, a three-phases coupling function could be satisfied. Comparing and analyzing relevant foreign documents, and through some experts evaluation, main technical data of this product comes up to the same level as those of similar products abroad.
RMU with three phases, 10kV rated voltage, 50Hz rated frequency, is suitable for power transmission and distribution system in places such as factory or mining enterprise, residential zone, high building, school, park, etc. It could also be used in ring net or terminal power supply.
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
