General

information and applications

The SBB ERS (Emergency Restoration System) towers are modular aluminium guyed structures. By establishing a temporary bypass system for damaged towers or towers under maintenance, they can help quickly restore power on a high-voltage power transmission line from 69kV to 1200kV.

When we designed the SBB system, we prioritized ease and speed for the installation. The aluminium base plate is laid directly on the ground, and no other foundation is required. The ERS equipment is lightweight and compact and can be installed on all ground and in all weather conditions.

Our ERS towers are delivered and stored in sea containers, allowing them to be ready for action and ensure the safety and protection of your grid.

Like a set of Lego ® blocks, the tower components' versatility allows you to combine them to create diverse configurations. As a result, the towers can meet all needs (suspension tower to tension or a terminal tower) and all situations (single circuit, double circuit, horizontal circuit, vertical or delta).

Creation of temporary gantries for substations.

It is possible to create new configurations such as temporary gantries for an electrical substation by using a special bracket that allows the installation of tower sections horizontally.

Increasing the electrical capacity of a line with the latest generation of conductors is now a common option. The SBB towers are suited for this work because they allow the conductors to level using successive bypasses while minimizing the duration of the power cuts on the line.

A regular SBB tower can become a crane that can hoist loads up to 3T with our crane module installed at the top of the tower. The construction of the transmission pylons in hard-to-reach places is then possible without having to build roads to move a traditional crane.

Configuration of protection gantries for conductors’ installation.

Configured as protection gantries, SBB towers can be used to install conductors over roads without interrupting traffic or power on an underlying line.

To meet the schedule of a new transmission line.

With a tight schedule, ERS SBB towers will allow you to meet your deadline and avoid significant penalties. Once the power is restored on time on the SBB towers temporary line, the construction of the permanent towers can be completed. The temporary line is then dismantled and the towers are stored in their containers until the next use.

When a power interruption is required, SBB towers can significantly reduce the power outage and thereby minimize the economic losses.
