Secondary systems: services and solutions for substation construction

In addition to our services in the construction of substations, we offer a comprehensive portfolio of services and solutions in the field of secondary systems.

Our services include the construction and renovation, as well as the upgrading and commissioning of control and protection systems, instrumentation systems and measuring and counting equipment. We design, assemble and document the secondary systems in your plant. We will also take care of the project planning, engineering and project coordination.

Our range of services is completed by the delivery and assembly of control and safety cabinets, substation interlocking, three-phase distributions, raised floor systems and custom products.

Field adaptation cabinet

Our field adaptation cabinet is an innovative outdoor field adaptation for compact integration of secondary systems associated with outdoor HV substations. This system solution provides a standardised platform for integrating field control technology, safety technology and local control systems.

Low-voltage distribution

Our solution for low-voltage distribution is a substation assembly in accordance with DIN EN 60 439-1. It has a modular construction and can be configured out of numerous cabinets if required: Infeed, coupling and outflow cabinet. By not using a continuous busbar, you can remain flexible and can add or remove cabinets at any time within the cabinet row.

Raised floor systems

In functional areas for substations, cables and wires in control rooms, as well as IT and computing facilities must be accessible. With our raised floor system (type LCP-B), we give you easy access to the entire line infrastructure — at any time, flexible and secure.

Network protection systems

We design, install and test electromechanical, electronic and digital protection relays for network protection, generator protection, motor protection and transformer controllers. Our service teams take care of commissioning and repeat testing of protection relays from all leading manufacturers directly on-site. In the case of a fault, we will create failure analyses and recommendations for improvement.
