Today over 1350000 Ormazabal medium voltage functional units have been installed in the electrical networks of over 100 electrical utilities and 600 wind farms in more than 110 countries.

    Following the success of our well known ga, cgm, cgc and gae type fully metal-enclosed GIS systems, the first cgmcosmos was launched in 2000, as the most flexible modular and compact ring main unit (RMU) range for secondary distribution networks up to 24 kV. Thanks to our Spanish and German R&D teams' spirit of continuous innovation, cgmcosmos system has been continuously evolving into a more extended range with higher ratings based on our customers' demands. Being manufactured 100 % in Europe, cgmcosmos system has already been integrated into several Smart Grid applications. Currently more than 400000 cgmcosmos functional units have been in service in more than 60 countries.

  • cpg Medium Voltage Switchgear - Power Substations
    cpg system is a high duty and extensible Gas Insulated Switchgear up to 38 kV. cpg system has already been integrated into several Utility, RES and industrial applications. Currently more than 7,000 units have been in service in more than 25 countries....

  • The cpg.0 & cpg.1 families are single busbar and double-busbar metal enclosed Gas Insulated Switchgear (GIS), consisting of medium voltage components such as circuit-breakers and disconnectors, which can be safely operated in confined spaces. This is thanks to its advance design where all active parts are contained into a stainless steel tight enclosure that ensures working conditions for its entire life.

    The product is 100% production tested to give best in class operation safety. Its modular design allows diagram extensibility to both sides without gas handling while offers frontal access for an easy installation and testing of power cables. P&C customization includes mechanical and electrical interlocks to prevent misoperation. Product robustness has been tested in case of internal arc fault.

    cpg systems provide maximum operational reliability as a prerequisite for the remote control and automation of power networks. GIS is invulnerable to pollution, vermin and atmospheric conditions. Sealed interrupters using vacuum as the dielectric medium have greatly improved life expectancy of circuit breakers while greatly reduces the need of shutdowns for maintenance.
