    PrefaceOrmazabal's decades of experience in the research, design, development, production and installation of medium voltage switchgear and switching devices has made us a global leading provider of gas-insulated medium voltage switchgears (GIS). Today around 1,300,000 Ormazabal MV functional units have been installed in the electrical networks of over 100 electrical utilities and 600 wind farms in more than 110countries.

    With the first ga, the most robust and compact series of block switchgears (RMU) was introduced in 1985 under the name ga-24 for secondary distribution networks of up to 24 kV.

    Due to the requirements of our customers, the modular version of the ga (then called GE) was developed in 1993. In 2001, this type was replaced with the gae series of switchgears.

    The gae switchgear series has since been continuously improved to address the needs of our customers and markets. Today more than 200,000 gae system functional units have been installed in more than 80 countries.

    The gae1250 and gae1250kmax switchgears are reliable and efficient solutions for energy utilities, industrial customers and for renewable energy.

    Ormazabal is the leading provider of customized solutions to electrical utilities, to electrical end users as well as renewable energy systems applications based on its own technology.

    We encourage the development of the electrical sector towards the challenges of the future energy needs. We cooperate with the worlds leading local, regional and global companies in the electrical sector with a strong commitment to innovation towards personal safety, network reliability, energy efficiency, and sustainability.

    Our highly qualified and focused team of innovation-motivated professionals have developed our own products and solutions during our more than a century long consolidated history, always by establishing close relationship with our customers aimed at achieving mutual long term benefits.

    Velatia is a family-run, industrial, technological and benchmark global group which operates in the areas of electrical networks, electronics and communication networks as well as in the consulting, security and aeronautics component sectors, where safety, efficiency and reliability are valued.

    Our customer orientation has led to the development of our extensive network of factories in Spain, France, Germany, Poland, Brazil, Mexico and China, helping to meet our customers needs in more than 50 countries.

    The solutions of the companies in Velatia seek to make the world a more and better connected, more sustainable, smarter, safer, more humane place.

    SafetyProtection for people, the environment and electrical installations.

    Special attention paid to the personal safety of the operators and the general public.

    Arc-fault protection Both the gae1250 and the gae1250kmax are protected against arc-fault according to IEC62271-200:

    gae1250: IAC AFL 20kA, 1s

    gae1250kmax: IAC AFL 25kA, 1s

    All high voltage areas fulfil the requirements of arc resistance according to IEC 62271- 200 Appendix A Criteria 1 to 5.

    In principle, the internal arc classification IAC AFL is always valid for the gas tank and the cable connection compartment.

    A rear absorber channel is optionally available on request, which enables the installation of the switchgear in connection with metal absorbers on a closed floor. By means of this option, the pressure value inside the switchgear room can be reduced by approximately 60%, and additionally it is passive & maintenance free.

    Hermetically sealedOperational safety is ensured by the hermetic sealing of the primary components, which protect against environmental influences such as dirt, moisture, etc. The drive parts are low maintenance and accessible from theoutside.

    InterlocksThe gae1250 and the gae1250kmax have mechanical and electrical interlocks according to IEC 62271-200 to provide a safe and reliable operation.

    Interlocks prevent unsafe operations:

    The switching devices are interlocked

    The cable connection compartment can be opened only if the earthing switch is closed

    Additional mechanical and electrical interlocks are available upon request.

    ReliabilityFor an uninterrupted supply of your electrical network.

    Permanent operation The SF6 HV compartment is maintenance free and the whole switchgear is designed for a life span of min. 40 years.

    Suitable for any environment Largely independent of climate.

    Use of controlled cable connection partsResistant to aggressive environmental conditions (humidity, salinity, dust, pollution, etc.).

    100% of parts quality controlledAll switchgear are subjected to 100% quality control.

    For example:

    Device function tests

    Withstand voltage test 50kV / 1 min

    Testing of all auxiliary devices such as auxiliary switches, shunt release remote control equipment, protective equipment, measuring inst
