Eaton Introduces Xiria E, the extendable single panel version of the internationally successful Xiria medium voltage switchgear

Eaton’s Electrical Sector is launching new IEC switchgear called Xiria E. Xiria E is the new Extendable single panel version of the internationally successful Xiria switchgear range for medium-voltage distribution networks. The Xiria E is specially developed for distribution substations for utilities and bigger commercial and industrial applications.

Eaton increases the flexibility of the Xiria product family by adding modular extendable panel versions with the possibility of a low-voltage top compartment for secondary control equipment. With the Xiria E, Eaton adds a single panel version to the current Xiria block-type switchgear. The modular single panel can be extended with a simple coupling connection. The system is highly flexible and contains a broad range of protection and control options. The E-version creates maximum flexibility and enables the possibility for future extension of secondary switchgear systems.

The Xiria name is known as a SF6-free, reliable and economic solution for ring main units and industrial switchgear. Xiria switchgear is characterized by the high level of operational safety and is suitable for applications up to 24 kV. Xiria switchgear is one of the most compact switchgear systems on the market. The switchgear is currently available as two-, three-, four- or five-panel block-configurations.

By adding the Xiria E panel to the current range of Xiria, a complete family, based on the same and proven key technologies, is created. The Xiria block-type system is already frequently used for transformers stations, small industries and commercial buildings. With the new Xiria E panel it is also possible to use the system for distribution substations for utilities and various other feed-in applications.

There are two basic panel versions in the Xiria product family:

• A vacuum load-break switch for ring cable connections up to 630 A
• A vacuum circuit-breaker for protecting transformers and cable connections up to 630 A

Xiria E is available for both panel versions and can be configured in any desired combination and sequence. For power consumption metering a special metering panel is developed that can be connected to the current block type switchgear and the new single panel Xiria E.

Xiria switchgear is designed around Eaton’s proven vacuum interrupters, which require no maintenance and are certified for 30,000 operation cycles. With the development of the Xiria E also a circuit-breaker with rated normal current of 630 A at 24 kilovolt is introduced in the block-type and single panel versions. This breaker type is tested for a rated short-time withstand current of 20 kA during 3 seconds.

Both the primary parts of the unit and the mechanisms are housed in a fully enclosed (sealed for life) housing which protects the whole system against environmental influences and therefore makes it maintenance free.

All live parts in the available panels are single pole insulated. The used materials are shaped specifically to provide optimum insulation characteristics combined with excellent thermal characteristics. In addition, the insulation is configured to provide effective control over electric fields around the used components, thereby minimizing any risk of internal arcing.

The use of vacuum interrupters and solid insulation means that the Xiria family is environmentally friendly. These technologies ensure that this system is a conservational alternative to switchgear systems using Sulfur Hexafluoride (SF6) gas for insulation. The cost of ownership is also significantly reduced. As no regular testing of gas pressure or other routine maintenance is needed and there is no high end-of-life disposal costs associated with ultimately disposing of the equipment.

With panel dimensions of only 350 mm width (block-type) and 500 mm width (Extendable version) and a provision for cable connection from the front, the Xiria system is economical in its use of valuable floor space, and easy to accommodate in even the most restricted environments. For locations without a possibility to exhaust an internal arc into the cellar, the Xiria system has the possibility to exhaust into the room. This is realized by means of a special chimney with integrated arc absorbers.

When it comes to the safety of the operating personnel the Xiria design leaves nothing to chance. All parts are fully enclosed by an internal arc tested safe metal housing. Besides that the panels in the Xiria family are provided with direct visible indication of the integrated earthing and ON/OFF position by means of inspection windows in the front.

Xiria E is an extension to the successful Eaton product family MMS (double busbar switchgear), Power Xpert® UX (withdrawable switchgear), W-VACi (vacuum circuit breakers) and Power Xpert® FMX (demountable plug in switchgear). In combination with Eaton’s low voltage switchgear, busbar systems, UPS products, project management and service capabilities, the Xiria E can be part of a state of the art complete solution.

The design makes the Xiria E system especially suitable for applications where a reliable, safe, economic and clean environment is necessary.
