5 Reliable both offshore and onshore Wind parks also have specific requirements, not only with respect to the place of use. Our gas-insulated medium-voltage switchgear, with its climate-independent maintenance-free technology and minimal space requirements, enable safe connection of the wind parks to the power grid and make a sustainable contribution to environmental protection. Trouble-free in the mining industry If you need maximum availability and reliability under extreme conditions, such as in lignite open-cast mining, then gasinsulated medium-voltage switchgear from Siemens is the first choice. It functions trouble-free around-the-clock in an atmosphere of electrically conducting coal dust under the most varied of ambient temperatures and under high mechanical stresses. High-performance in the metal industry The performance demands in metal industry companies are enormous: Connection loads of up to 300 MW this corresponds to a power consumption of more than 300,000 households are common. Our gas-insulated medium-voltage switchgear can support the safe flow of all processes by reliably switching and distributing large quantities of power. The hardest conditions in the oil and gas industry Exploration and conveyor systems in the oil and gas industry must have a troublefree, safe power supply and require maximum power in the tightest of spaces. Gasinsulated medium-voltage switchgear from Siemens reliably performs its tasks even under extreme conditions. Therefore, they are particularly well-suited for oil and gas applications because operational safety and availability are absolutely necessary. Safety and compactness for modern infrastructure Modern infrastructure such as airports and office buildings are placing increasingly higher demands on safety, flexibility, and less environmental pollution over the entire service life. Our compact, gas-insulated medium-voltage switchgear in this case helps to support the establishment of safe medium-voltage power distribution and reliably provide power to large consumers and the low-voltage system. For almost any application Gas-insulated mediumvoltage switchgear from Siemens also ensures optimum current flow in other applications such as computing centers or branches such as the automotive industry, chemical industry, and the food and beverage industry. 5

6 Impressive advantages Future-proof investment In these times of growing cost and performance pressure, it is even more important to decide on the right technology, especially when switchgear represents an investment for decades. Compactness, performance capability, climate independence, and cost-efficiency in this case supplement the central aspects of gas-insulated medium-voltage switchgear from Siemens making it a sound investment for the future; it also provides optimum personal and functional safety and reliable, maintenance-free operation. In addition, our service contributes to power distribution: Within the scope of Totally Integrated Power, we offer you much more than products, systems, and solutions for power distribution. We will support you through the entire process and life-cycle of switchgear starting from the initial idea to completion and aftersales service. We offer tools for planning of switchgear and system architecture, help with energy management and monitoring, and we offer training and education in the perfect use of our product line. 6

7 Compact A gas-insulated medium-voltage switchgear also assures you many advantages in the future due to the technically superior solutions including protection of your investments from the target-oriented switchgear extension. Thanks to its compact construction, it offers you space savings of up to 70 % with the 36 kv switchgear for primary distribution and provides the space for new functions or the compact design of transformer substations. Maintenance-free A cost-efficient operation is one of the key factors for system operators. This also includes particularly long maintenance intervals. Hermetically-sealed, welded switchgear vessels made of stainless steel (sealed pressure system) ensure tightness for the entire service life as per IEC , which means that maintenance of function is normally determined by the service life of the switchgear inside. This is determined, for example, for vacuum circuit-breakers under normal ambient conditions as per IEC with up to 10,000 operating cycles without relubrication or readjustment. Our switchgear is therefore practically maintenance-free which ensures maximum availability with extensive cost-efficiency. Climate-independent Even under the most extreme ambient conditions, such as salty air, high air humidity, conductive dust or condensation, our gas-insulated switchgear has proven to be the ideal solution and, depending on the switchgear design, will fulfill your needs regardless of air pressure or altitude. They are reliable, owing to the superior technology which ensures the safety of your distribution system. Intelligent With respect to integration into the upstream control and energy management systems: There are a variety of communication and telecontrol units available for implementing an interface via various protocols (e.g. IEC 61850, IEC /104, PROFIBUS, MODBUS, DNP). In the age of intelligent grids, so-called Smart Grids, stations must be able to integrate smoothly into the new grid control structures. To do this, medium-voltage switchgear should be equipped, amongst other things, with motor drives and compact telecontrol units. Depending on the configuration, errors can be localized more quickly, and measured values can be gathered and transferred. In addition, load curves can be recorded, overloads can be detected early on, decentralized supply can be controlled, and losses in the distribution system can be minimized. 7

8 Personal safety Gas-insulated medium-voltage switchgear from Siemens is very safe. They meet international safety requirements and are internal arc classified in accordance with IEC This high level of safety is achieved, among other things, by design measures such as the hermetically sealed, shock-proof primary enclosure and the metal enclosure of all high-voltage conducting parts, including cable terminations, busbars, and voltage transformers, as well as earthed sheathing. In addition to standard protection class IP 65 for all high-voltage parts, the primary circuit ensures advanced control logic to provide additional safety. Logical mechanical interlocks prevent maloperation. In addition, safe isolation from supply can be verified with a capacitive voltage detecting system. All operating mechanisms and auxiliary switches are accessible outside the primary enclosure without danger, while operation is possible, depending on the system, only with the switchgear enclosure closed. Security of operation Cost-efficient goals go hand-in-hand with a high level of operational safety. Gas-insulated switchgear from Siemens will support you with a largely maintenance-free, stable, and tested design for maximum availability even under extreme environmental conditions. Thus, the hermetically sealed primary enclosure makes the switchgear insensitive to environmental influences but also to the penetration of foreign objects or small animals. No significant electrical fields occur outside the enclosure, which means that no partial discharge can occur via pollution layers in the long term. In addition, the welded switchgear vessels are sealed for life, and the electrical and thermal stresses of the current transformers as well as the low-voltage components are practically zero. Environmentally responsible Our manufacturing plants are certified in accordance with DIN EN ISO we place particular value on the preservation of resources in all of our production processes. This also means that we select environmentally compatible materials, even at the product development phase, and minimize the material and energy consumption through production-friendly development. Thus, our gas-insulated switchgear has a small "footprint" not only because of the compact design but also from an ecological perspective. 8

9 After its service life, lasting decades, is over, we take on the responsibility of recycling the switchgear in accordance with the valid standards. Reliable With long-lasting products such as our gas-insulated medium-voltage switchgear, absolute quality, precisely tailored to the specific preconditions and requirements of the place of use, is at the focal point of our work. We achieve optimum adaptation to local challenges through our internationally constituted development teams and customer-oriented manufacturing centers, which are certified according to DIN EN ISO 9001 and Crucial for highquality, however, is not only the management systems but also excellent training and education of our employees and the use of innovative technologies such as highly precise laser welding systems that we use to ensure that the vessels will have high gas-tightness levels. The electric bushings of the stainless steel vessels are welded without seals as are the mechanisms for transferring the operating energy to the switching devices within the vessel. In addition, we check every switchgear vessel with helium in the vacuum test cell for leaks. Our goal for each individual switchgear vessel is "Sealed for life". We also do not compromise with crucial components such as insulation parts made of cast resin; instead, we produce them ourselves and ensure their quality and function 100 % by X-ray and tightness, high-voltage, and partial discharge testing.
