5 Security for utilities Cost-efficient and safe: Gas-insulated medium-voltage switchgear from Siemens convinces utilities all around the globe because of its high personal safety, operational reliability, and cost-efficient operation made possible by a maintenance-free and trouble-free design. Moreover, utilities benefit from the minimized dimensions of gas-insulated switchgear from Siemens, which simplify the construction of compact local transformer substations, or their remodeling or retrofitting. Reliable offshore and onshore Wind farms also have high requirements, not only regarding their place of installation. The climateindependent, maintenance-free technology and minimum space requirements of gas-insulated medium-voltage switchgear from Siemens enable the safe connection of the wind farms to the power grid. Reliable for mining applications Where maximum availability and reliability are requested under extreme conditions, e.g. in lignite open-cast mines, gas-insulated medium-voltage switchgear from Siemens is the first choice. The equipment operates around the clock without disturbance in an atmosphere of electrically conductive coal dust, at very different temperatures, and under high mechanical stress. High performance in the metal industry The metal industry requires extremely high performance levels: loads of up to 300 MW which correspond to the power consumption of more than 300,000 households are no exception. Here, gas-insulated medium-voltage switchgear from Siemens supports the safe execution of all processes by reliably switching and distributing these large amounts of energy. Hardest conditions in the oil and gas industry Exploration and conveying systems in the oil and gas industry are dependent on a smooth, safe power supply, and require maximum power on minimum space: Gasinsulated medium-voltage switchgear from Siemens is installed in the climatically most demanding areas of the world: in the open sea, in the tropics, or in arctic regions. Safety and compactness for modern infrastructure Ever increasing demands in respect of safety, flexibility and low environmental impact are placed on modern infrastructure such as airports or office buildings throughout their entire service life. Our compact gas-insulated medium-voltage switchgear helps to develop a safe medium-voltage power distribution grid and reliably supply large consumers or the low-voltage grid. For further applications, e.g. in data centers or sectors such as the automotive, chemical, or food and beverage industries, gas-insulated medium-voltage switchgear from Siemens ensures an optimum flow of power. 5

6 Convincing advantages At a time of growing cost and performance pressure it is even more important to decide on the right technology, above all because switchgear represents an investment for the next decades. Compactness, performance, climatic independence and cost efficiency add to the central aspects of gas-insulated medium-voltage switchgear from Siemens in order to provide a future-proof investment: optimal personal and functional safety, as well as reliable, maintenance-free operation. 6

7 Compact A gas-insulated medium-voltage switchgear assembly provides you with many advantages by means of technologically outstanding solutions, including the protection of your investments by targeted switchgear extensions. Its compactness offers space savings of up to 70 % for 36 kv primary distribution switchgear - and free space for new functions or the compact design of local transformer substations. Maintenance-free Cost-efficient operation is one of the key factors for switchgear operators. This also involves especially long maintenance intervals. Hermetically welded stainless-steel switchgear vessels (sealed pressure system) provide tightness for lifetime according to IEC , which means that the preservation of function is normally determined by the service life of the incorporated switching devices. Under normal conditions, for example, vacuum circuit-breakers are designed according to IEC with up to 10,000 operating cycles without relubrication or readjustment. This makes our switchgear practically maintenance-free for maximum availability at high cost-efficiency. Climate-independent Even under most extreme ambient conditions (such as saline air, high air humidity, conductive dusts or condensation), our switchgear proves to be the ideal solution, fulfilling its function independently of the air pressure or the site altitude, depending on the switchgear design. Reliability by outstanding technology for the security of your power distribution. Intelligent In addition, concerning the integration in higher-level control, protection and energy management systems: For this purpose there are multiple communication and telecontrol devices available to implement the connection via different protocols (e.g., IEC 61850, IEC /104, PROFIBUS, MODBUS, DNP). In times of intelligent networks, so-called Smart Grids, the substations must be capable of integrating smoothly into the new network control structures. For this reason, medium-voltage switchgear should be equipped, among others, with motor operating mechanisms and compact telecontrol units. Depending on the degree to which the switchgear is equipped, faults are faster to locate, and measured values can be collected and transmitted. Load characteristics can also be recorded, overloads are detected earlier, decentralized power supplies can be controlled, and losses in the distribution grid are minimized. 7

8 Personal safety Gas-insulated medium-voltage switchgear from Siemens is constructed in a particularly safe manner. It meets international safety requirements and is internal arc classified according to IEC This high safety standard is achieved, among others, by constructional measures such as the hermetically sealed, safe-to-touch primary enclosure and the metal enclosure of all parts under high voltage, including the cable terminations, busbars and voltage transformers as well as their earthed enclosure. Besides the standard degree of protection IP 65 for all parts of the primary circuit under high voltage, a sophisticated operating logic offers additional safety. Logical mechanical interlocks prevent maloperation. Furthermore, safe isolation from supply can be verified by means of a capacitive voltage detecting system, and all operating mechanisms and auxiliary switches are accessible without danger outside the primary enclosure, while operation is only possible with closed switchgear enclosure due to the system design. Security of operation Economic targets go hand in hand with a high operational reliability. Gas-insulated switchgear from Siemens supports you with an almost maintenance-free, robust and tested design for maximum availability even under extreme environmental conditions. The hermetically sealed primary enclosure makes the switchgear insensitive to environmental influences (such as dust), but also to ingress of foreign objects or small animals. Outside the enclosure there are no appreciable electric fields, so that partial discharges caused by pollution layers will not appear at long term either. In addition, the welded switchgear vessels are sealed for life, and the electrical respectively thermal stress of the current transformers as well as the low-voltage components is almost reduced to zero. Environmentally responsible Our production locations are certified to DIN EN ISO we pay particular attention to the preservation of resources throughout all production processes. This also means that we select environmentally compatible products already in the phase of product development, and reduce the material and energy expenses in the manufacture by a production-friendly development. In this way, our gas-insulated switchgear leaves only a small footprint, not only due to its compact design, but also ecologically. After decades of service, we assume the responsibility to recycle the switchgear in accordance with the applicable regulations. 8

9 Reliable For long-lasting products such as gas-insulated mediumvoltage switchgear from Siemens, absolute quality, matching exactly with the specific prerequisites and requirements of the place of installation, are in the focus of our work. Optimum adjustment to the local challenges is reached by internationally staffed development teams as well as by production centers located close to the customers, certified to DIN EN ISO 9001 and However, the decisive issue for high quality are not only the management systems, but also the comprehensive training of our employees, and the use of innovative technologies such as high-precision laser welding equipment, which allows us to ensure the high gas tightness of the vessels. The electrical bushings of the stainless-steel vessels are welded in without seals just like the linkage mechanisms for transferring the operating energies to the switching devices inside the vessels. Furthermore we test every switchgear vessel for tightness in the vacuum test chamber using helium. Our target for each individual switchgear vessel is sealed for life. And when it comes to match-winning components, e.g. insulating parts made of cast resin, we make no compromises, but rely on our own production, securing their quality and function to 100 % via X-ray, tightness, highvoltage, and partial discharge routine tests.
