Access walkways for GIS

Walkway over control box for GIS

ESLA performs different manufacturing and installing access walkways for maintenance of equipment of Gas-insulated switchgear GIS Substations.

The gas insulated switchgear (GIS) currently represents an advance over conventional AIS substations outside. Its modular and compact design reduces space required for installation and are suitable for indoors.

The company ABB is the pioneer in GIS technology. The required maintenance of equipment, although there are much less than conventional AIS turns out to be difficult to access, so the installation of structures and walkways ESLA necessary.

The walkways placed over control box give access to the various controls of stairs by turning breakers that can be replicated if necessary.

Made of aluminum alloy with a modular system that allows the necessary adjustments to the provision of all its elements.

They have walkways bridge type over circuit breakers with access to both sides.
