Product Portfolio

  • Pitch Systems

  • Experience from A to Z instead of according to books:
    Our pitch systems.

    We learned the ABC’s of pitch systems more than 20 years ago. From A as in active-stall blade pitching, which we developed in 1992, to Z for Z-axis. We haven’t just participated in the development of pitch systems, we pioneered the electric pitch system and launched it into the market.

    The detailed engineering and design of pitch systems in the hub has become a part of our service portfolio, as has the development of new technologies which make pitch systems more efficient and reliable. For example with the new generation of MPC series converters. At SSB Wind Systems, the letter P continues to stand for progress.

          • Safety Philosophy

          • Philosophies generally sound good. But even the greatest ideas are only worthwhile if they can be put into practice. The same applies to our safety philosophy:

            Every one of our pitch systems is built so that the safety function of each axis operates fully independent of each other. The same goes for the motor control, the emergency power supply, as well as the switch cabinets and wiring systems. With 17,500 pitch systems installed worldwide we have had many opportunities to put these requirements to the test.

          • Our philosophy: Safety has to be put to the test.

            • The pitch system must be able to be used as a primary brake without any compromises.
            • The turbine must be able to be stopped safely under any operating conditions.
            • The minimum requirement is being able to turn a blade to the feathering position to achieve a safe minimum speed (Fail-Safe).

          • Emergency Power Supply

          • In an emergency or during unexpected downtimes, the pitch system must be capable of returning the rotar blades at a fixed speed to a safe 90° position. Even during a network failure. This is one of the directives established by Germanischen Lloyd. For us it’s a given. Of course the pitch system then requires an uninterrupted power supply (UPS).

            This is accomplished with batteries or ultracapacitors. And because we never make compromises when it comes to safety, we offer both technologies and recommend the optimal system for your WTG type. Ranging from voltages of 144 V, 216 V, 288 V … you need only remember one figure: 100 %. That is the only acceptable safety standard when it comes to your WTG.

          • There’s always a way to get things going again: Emergency Power Supply.

          • Pitch Drives

          • Always doing the same thing can be very exciting. This is the experience made by our engineers who are always challenged with something new – every one of our pitch drives is unique. Every motor, whether AC or DC is individual in size, design and performance parameters. We orient ourselves in accordance to your needs, your WTG type, the location and resulting demands on the motors.

          • We treat AC and DC motors exactly the same: Individually.

          • Happy for a change:
            Our AC Motors.            		 Consistently reliable:

          • Axis and central controller cabinets

          • The one swears by overall product design, the other is satisfied by the accessories. We make no such compromises. Rather we focus on a total solution, and that means not limiting ourselves to the construction and producing of switch and control cabinets according to your demands. We also provide you with equally high quality accessories by, for example, installing all the cables ourselves. That means that every cabinet is completed according to your demands and the technical specifications of your WTG.

          • There is more in it for you: Our axis and central controller cabinets.

          • With no ifs or buts: Our

        • Switch and Control Cabinets

        • Every switch and control cabinet is equipped with something very unique: The special requirements demanded by a customer for a highly individual WTG. There’s good reason why we are always striving to set new standards in planning, development and production. At the end of the day, there is always a particularly high standard which has to be reached: Yours.

            • Top and Tower Boxes

            • The soul of a wind turbine is contained in the top and tower boxes regardless whether at its base or in the nacelle. This is where all information converges, is processed and results in the optimal positioning of your WTG vis-a-vis the wind. There could be no greater need for extreme reliability and safety than here.

              A standard configuration from SSB Wind Systems is one that sets standards. Either with custom designed housing, SPS, vibration sensors or other components. Each optimally coordinated with one another. By the way. When you are not only looking for the optimal, but also the perfect solution: Every top and tower box can be enhanced with a variety of options such as touchscreens, etc.

            • Brimming with ideas: Our Top and Tower Boxes

            • Operating and Testing Boxes

            • Even in unexpected situations, there should be nothing unexpected when it comes to safety and reliability. Rather you should be able to take them for granted. For example, when it comes to the assembly or start-up operations of a WTG. The mobile boxes from SSB Wind Systems help you keep control of all relevant functions throughout this initial phase. Completely independent from axis and control cabinets or the complete nacelle for that matter. Big ideas find a way to fit into even the smallest boxes.

            • Happiness knows no bounds: Our mobile boxes

            • Our mobile
              hub simulation box.              		 Our mobile

            • Custom Solutions

            • SSB Wind Systems are in the habit of expecting particularly good performances. But occasionally these have to be even better than usual. Our engineers understand this. And they always find a way. For example, with a solution for your wind park management system. Or with cabinets or grid integration of your wind park, always meeting the individual requirements established by the grid operator.

              无论需要定制解决方案for your WTG, wind park or fleet, we can develop and implement it. Something very special is transformed in something you can take for granted.

              • Our start-up operations service

              • Triple redundancy: That is a key safety element of every SSB Wind Systems pitch system. It is also the minimum requirement for our handling of the system for your start-up operations. You’ll see: The way to a perfect pitch system is not long, just consequent. Our goal is not just that your system runs: We want it to run three times better than normal

                First step:

                We ensure that things run really well on-site..

                Second step:

                We ensure that things run even better on-site.

                Third step:

                We ensure that your WTG runs perfectly on-site.

              • A smart approach: Our training.

              • The experience of developing each pitch system in close cooperation with our customers has taught us the value of sharing our know-how. This continues long after the development phase. For example, by request we will train the service engineers and fitters at your production facilitieson how to optimally implement the pitch system in the hub of your WTG or on an individually determined subject. The training can also be carried out directly at the WTG site itself.

              • Need a spare part? We've got just what you need.

              • That’s exactly how it should be. We offer spare parts supply for the entire 20-year lifecycle of a WTG for all systems supplied by us. So that you don’t have to wait that long for your spare parts, we have a large number of parts, upgrades, and even complete retrofits in stock.

                You can rest assured that even the most hard to get components such as converters, controllers or battery packs are available immediately – when necessary, even by express mail directly to your desk. Naturally, we make curbside deliveries of items such as a complete spare cabinet. We’ll even produce it from scratch when necesary with all the necessary interfaces and functions compatible with your WTG. Nothing less really than you should expect.
