Gas-insulated medium-voltage switchgear Answers for energy. SIEMENS

Full power even under extreme conditions The worldwide demand for energy is still rising, and fossil energy sources are playing the decisive role in fulfilling this demand. Deposits whose exploitation was considered uneconomical in the past are constantly gaining importance in view of increased raw-material prices, and thanks to new extraction and processing methods. This applies to remote regions in the Arctic or the Antarctic, as well as for the Canadian oil sands. The environmental conditions, under which processes in the oil and gas industry take place, are increasingly harsh and...

Superior technology for demanding tasks Highly available, maintenance-free, compact, robust: Gas-insulated mediumvoltage switchgear from Siemens provides a convincing solution, even under the most extreme conditions. A worldwide unique, hermetically welded pressure system in a stainless-steel vessel, vacuum switching technology, and a digital protection system make it independent from environmental conditions, and provide maintenancefree operation for life. On top of that, the SF6 insulation enables an extremely compact construction. The result: minimum operating costs, maximum performance,...

The challenge: maximum performance around the clock The challenge: reliable operation despite extreme environmental conditions Energy supply for processes in the oil and gas industry must operate with absolute reliability around the clock. Electric power of up to 900 MW is required for such processes, and each breakdown in the supply would mean production stoppage and high losses. That is why reliable operation is an absolute must for medium-voltage switchgear for the oil and gas industry, so that the enormous energy demand can be covered at all times, both in the 30 kV and in the 6/11 kV...

Stress-resistant The challenge: maximum operational safety, even under oscillations and impacts Switchgear on ships and platforms is constantly subjected to oscillations and vibrations caused by running aggregates and propellers. At rough sea, the equipment is also affected by considerable horizontal and vertical accelerations – a real test for the dielectric strength of the switchgear, the solidity of the SF6 enclosure, and for all mechanical components. Even so, the switchgear must be able to operate reliably at all times. Compact The Siemens solution: intelligent engineering and...

The challenge: perfect integration in control and automation systems The challenge: particularly high switching rates The challenge: maximum availability, minimum operating costs Medium-voltage switchgear units in the oil and gas industry are decisive network nodes and must meet the highest safety requirements in every respect, both for processes and personnel. Theoretical and practical knowledge in this industry differs from operator to operator, so it is extremely important that the switchgear is fully integratable in the control and automation environment of the complete system, for...

Highly performant The challenge: maximum reliability and availability in regions prone to earthquakes The challenge: safe control of high currents Oil and gas plants are often built in regions with an above-average earthquake risk. In certain parts of the globe, several minor earthquakes a day are not unusual. This places high demands on the medium-voltage switchgear used in those plants. Despite severe jolts and vibrations, the switchgear must operate continuously, reliably, and with a maximum degree of safety. The Siemens solution: constructional solutions and comprehensive test Our...
