Product Description

Medium voltage products

GSec

Gas-insulated switching and isolating apparatus

1.description


GSec is a three position SF6 gas insulated switch disconnector designed for use in medium voltage switchgear for secondary distribution up to 24KV, 800A, 25kA. GSec is used in line ingoing/outgoing panels, in those with circuit-breakers or in a combination with fuses. Typical applications are supplying lines, protecting transformers and use in ring networks.  Thanks to its size, GSec can be installed in panels 375mm in width or wider.

Thanks to its size, GSec can be installed in panels 375mm in width or wider.

The contacts of the three phase can be set to the following positions: LINE-OPEN-EARTH.

The enclosure of the GSec switch disconnector consists of two half-shells, the top part being made of resin and the bottom part in stainless steel.

GSec apparatus is "sealed for life" in accordance with standard IEC 62271-1, which means that the gas tightness is guaranteed for more than 30 years.

Gsec has a wide range of " plug&play" accessories that can be easily installed and replaced from the front part of the apparatus.

The GSec series has been designed and tested in compliance with standards IEC 62271-1, IEC 62271-102, IEC 62271-105 and IEC 62271-103.

The switch-disconnector has also been tested for use at low temperatures and type approved for naval applications(Germanischer Lloyd register).

Safety

The stainless steel bottom part of GSec provides metallic segregation between the cable and busbar compartments, ensuring that the two compartments are earthed and therefore making conditions safer for the personnel.

Thanks to GSec design, it can be used to create switchgear with PM(metallic partitions) classification for the segregation between the busbar and cable compartments.

Mechanical interlocks for the safety of the personnel.

The door lock prevents the panel door from being opened when the GSec contacts are not in the earthed position. Vice versa, the lock prevents the switch-disconnector from setting to the open or line positions when the door is open.

The operating lever with "anti-reflex" function.

Maintenance free

The enclosure of GSec is guaranteed " sealed for life" for more than 30 years, in accordance with IEC 62271-1 standards.

Up to 5000 mechanical operations without maintenance for GSec with the 1S-single spring operating mechanism.

Up to 1000 mechanical operations without maintenance for GSec with the 2S-Double spring operating mechanism.

Reliability 

The apparatus can house VPIS voltage indicators in accordance with standard IEC 61958, for voltage detection on the cable side.

Mechanical signaling of the state of the apparatus connected directly to the operating shaft(annex A of standard IEC 62271-102).

Ease of use

Both the GSec operating mechanisms are equipped with springs so the operating speed is independent of the operator.

The operating mechanism has two separate seats, one for line operation and one for earthing operation.

Customizing

A full range of " plug & play" accessories that can be easily installed on the front part of the operating mechanism allows the apparatus to be adapted to suit many applications.

GSec can be used for incoming/outgoing units, in combination with fuses, circuit-beakers with lateral operating mechanisms, current and voltage transformers.

Compactness

Thanks to the upper resin part it is possible to design small size apparatus and switchgear panel, while still ensuring a high level of insulation.

The capacitive sockets for voltage indicator (VPIS) and the cable connections are already integrated in the apparatus bottom insulators. This allows to reduce the number of components of the panel.
