Features and Benefits

With over 100 years in manufacturing switchgear, the ECOSMART GIS secondary distribution switchgear line offers a comprehensive range of functions. The unit is gas insulated to provide a low-maintenance, compact, safe, and easy-to-install product to meet the most difficult applications.

Designed to be a maintenance-free solution, the active parts of the ECOSMART GIS switchgear are contained and sealed in a stainless steel tank filled with gas, making it more compact compared to other insulation mediums. The gas can be easily recovered at the end of the product life through the filling valve positioned on the switchgear tank. The switchgear has been designed as a sealed pressure system as defined by IEC 62271-1.

Safety/Reliability:

• Total insulation of the live components is ensured by the welded stainless steel tank filled with gas (sealed pressure system as defined by the IEC 62271-200)

• Complete grounding of the whole switchgear• A complete interlocking system allows safe

operating sequences• Anti-reflex function of the operating lever• Switch-disconnector positive position indicator• Earthing switch with making capacity• Pressure relief valves located under the switchgear for

overpressure venting in the event of an internal arc• Internal arc fault protection both for the gas tank

and cable compartment (IAC classification: AFLR up to 20 kA x 1 second as per IEC 62271-200)

• Long service life• Pressure monitoring by included pressure

gauge and, upon request, a pressure switch with auxiliary contacts

ECOSMART GIS

Versatility:

• Compact and modular versions available• Fuses and vacuum circuit breaker protection functions• Wide range of accessories available • Easy installation• Maintenance free• Reduced footprint

Easy Operation:

• Operations are carried out from the switchgear front side• Mimic diagram indicating the position of the switch-

disconnector, earth switch and vacuum circuit breaker• Front cable connection and accessibility• Complete set of interlocks

Easy Installation and Handling:

• The compact design provides advantages during the switchgear installation, allowing:- Reduced installation rooms (kiosks, mobile substations, etc.)- Reduced civil works cost - Easy transport and handling

Environmental Care:

• Manufacturing energy optimization due to the switch-disconnector and cubicle components material

• Reduced use of epoxy resin components• Reduced gas quantity • Made of recyclable materials for ease of recovery and reuse at

the end of the product's life cycle

Extension Kits

Extension Kits

All units can be ordered in a modular version to allow installation of additional units on both the left and right hand side.

This is accomplished through the use of extension kits positioned on the top or sides of the unit. The modular RMU type must be specified before the units go into production.

Steel Tank

The live parts including switch-disconnectors, earth switches, vacuum circuit breakers and power busbars are housed inside a welded stainless steel tank and insulated with gas. To meet a wide variety of electrical configurations, it is possible to combine up to five functions inside a single tank.

All items are front accessible including the operating mechanisms, vacuum circuit breakers, fuse holders and medium voltage cables. Mechanical interlocks are provided between the 3-position switch-disconnector, the earth position, the vacuum circuit breaker and the cables compartment panels to permit operations only in safe conditions.

The line and earth contacts are driven by a 3-position operating mechanism with two different operating lever slots which are mechanically interlocked. On top of the vacuum circuit breaker function (CBS), a low voltage box can be installed to house the auxiliary circuits, measure instruments and to house the protection relays.

The bottom plates of the cables compartment are equipped with grommets to allow the medium voltage cables entry. Cable clamps are included to support and maintain the medium voltage cables. Floor fastening holes are included on the bottom of both sides of the switchgear as well as in each corner of the switchgear support frame.
