"Gas Insulated Switchgear Your partner in energy solutions CG Electric Systems Hungary CG Electric Systems Hungary previously known as Ganz Electric has a history of over a 130 years as a high technology company with a strong reputation for global engineering capabilities. Currently the company has three main manufacturing units: high-voltage switchgear, power transformers and rotating machines. The product line of high-voltage switchgear unit includes gas insulated switchgear GIS. Switchgear products are provided for application voltage range of 72.5-300 kV, normal currents up to 4000 A and short-time current of 40 kA. Many years of working experiences have proved and the continuous technical research and development have improved the following important general features of the new GIS type substations: small space requirement, easy and fast installation, high reliability, resistance against environmental and climatic effects, maximal safety for the personnel, minimal maintenance and long service life. All GIS products were developed by RD centre located in Budapest. Experienced development engineers and powerful state-of-the-art design and analysis software ensure optimised design to meet the requirements of all relevant IEC standards. Calculations include mechanical and electrical Finite Element Method analysis, as well as gas flow analysis for circuit breaker design. Design department, production factory, assembly workshop and test stations are working on the basis of a complex and very strict Quality Assurance System in compliance with the ISO 9001 standard. The factory also operates an Environment Management System certified to ISO14001. The systematic inspections and test measurements ensure the conformity of the end product to the Clients requirements and to International standard specifications.
