Retrofit for Gas Insulated Switchgear

§ Why a retrofit solution?§ Retrofit means upgrading existing system with modern

components, in order to optimize all technical, safetyeconomic and ecological concerns

§ With the retrofit solution, you can exchange just thecomponents that have been subjected to the most wearover their many years of reliable operation

§ The result of retrofit solution is a major improvement inreliability, safety, maintenance reduces and performance

§ Retrofit is ideal solution to ensure the optimum return oninvestment
