Transformer stations of up to 30 kV require careful planning and reliable implementation
-1020x681.jpg "Transformer stations of up to 30 kV")
Extensive planning, precise coordination and legally compliant construction are required for the construction of transformer stations up to 30 kV. At Frequenz Elektro GmbH, we have years of experience, a wide range of products, and excellent contacts with regulatory authorities. As a full-service provider, we offer not only the installation of transformer substations, but also integrated solutions incorporating low-voltage switchgear, cable systems and cable support systems, whether the project is new construction or retrofitting.
Construction details and official coordination
Our experts consider all the important structural factors:
- Housing and components: A transformer station comprises a building, a transformer, medium-voltage switchgear, and a low-voltage distribution board.
- System types: We differentiate between compact stations, walk-in transformer stations and built-in stations. Outdoor installations require extensive regulatory approval, particularly with regard to the distance from the company building.
Transformer types: the optimal solution for every application
Numerous criteria must be considered when choosing the right transformer:
- Dry-type transformers (cast resin transformers): These are ideal for indoor use in areas where space is limited, as they do not require an oil collection tank.
- Oil-immersed transformers: They offer lower noise emissions and greater robustness in humid environments. They provide efficient EMC protection thanks to their modern concrete installation stations and shielded steel tanks.
- Special applications: Esther-cooled transformers use a biodegradable coolant and are used in special industrial processes where oil is not permitted.
To reduce long-term operating costs and ensure rapid amortisation, we recommend devices with low loss classes.

Cable systems are safe, reliable and efficient
-1020x680.jpg "Cable systems")
Standard-compliant cable systems are the backbone of power engineering. Without proper planning and installation of cabling, transformer stations of up to 30 kV, emergency power systems and other components will not function effectively.
Frequenz Elektro GmbH safely, reliably and efficiently plans and implements electrical cable systems, from standard installations to specialised systems with integrated functional integrity.
Here are our services at a glance:
- Various cable types:
We install low-voltage cables for use in control, automation and security technology, such as fire alarm systems, video surveillance and access control systems.- Indoor use: Choose between a standard PVC cable and a halogen-free cable, which minimises fire load and is ideal for public facilities. This cable is also required by state building authorities.
- Outdoor: UV-protected cables for outdoor use.
- A special case of a functional integrity cable
These cables remain conductive when exposed to a direct flame for a defined period of time (30, 90 or 120 minutes), which is crucial for safety-critical applications such as emergency lighting, smoke extraction systems and fire service elevators. Our experts only use approved cable support systems and comply with all specific installation regulations. - Efficient cable laying:
We plan cable routes, ducts and cable trays in order to optimise capacity, heat dissipation and future expansion. We also consider aesthetic factors, installing cables in conduit systems beneath the floor slab or in discreet cable ducts rather than on visible trays on walls and ceilings. - Comprehensive planning and consultancy services:
Our experts will advise you on all technical and structural requirements, taking into account the regulations of the Model Line Installation Guideline (MLAR) and reviewing the capacities of grid operators. Thanks to our expertise, some of our customers have become medium-voltage grid operators – a solution that is both efficient and future-proof.
Cable support systems – precise planning and safe installation
-1020x680.jpg "Cable support systems")
A standard-compliant cable support system is essential for any electrical infrastructure. Frequenz Elektro GmbH plans and installs customised cable trays that are optimally tailored to your cable systems and meet all structural, safety and EMC requirements. Our experts can select from a wide range of cable support systems, including cable ladders, cable platforms, cable trays, special wide-span cable trays, mesh cable trays, wall brackets, risers, parapet ducts, media columns and floor box systems. These components are available in various lengths and weight classes, and in different materials such as Sendzimir galvanised steel, hot-dip galvanised steel, stainless steel and glass-fibre-reinforced plastic, to optimally adapt to your structural conditions and technical requirements.
We carry out our planning in parallel with the cable installation, taking into account aesthetic aspects, future expansion options and industry-specific standards, such as hygiene requirements in the food industry. Special cable support systems ensure that critical systems remain conductive for defined periods (30, 90 or 120 minutes) in the event of a fire.
A key quality aspect is electromagnetic compatibility (EMC). We achieve the necessary media separation by routing power and communication media in separate cable trays or different conduits. This prevents signal interference and the costly rework that can result from inadequate EMC measures.
Rely on Frequenz Elektro GmbH's many years of expertise – we are your competent partner for cable support systems and cable tray planning. Our solutions meet all legal standards and provide a reliable, high-performance infrastructure that is also attractive and affordable.
Emergency power system: a guarantee of an uninterrupted power supply
-1020x680.jpg "emergency power system")
Power outages or sudden voltage drops can threaten the existence of companies, government agencies and institutions. High availability is particularly important in data centres, pharmaceutical companies, hospitals and care homes. Frequenz Elektro GmbH offers innovative emergency power systems as a key component of energy technology to ensure a reliable, uninterruptible power supply. As energy technology specialists, we provide comprehensive solutions for the design, maintenance and servicing of your emergency power system. Thanks to our many years of experience and precise planning, we can guarantee an efficient, legally compliant and future-proof power supply, even during critical outages.
Fields of application and application scenarios
- Building regulations: The installation of a backup power system is required by law in many buildings (e.g. those with sprinkler systems or fire service elevators).
- Risk minimisation: Even though they are not legally required to do so, companies invest in their own emergency power systems to avoid the risk of production downtime and high damage costs.
Technical requirements and planning
Designing a backup power system can be challenging.
- Duration of operation and maintenance intervals: The specifications regulate how long the backup supply must be guaranteed for, and how frequently the system must be maintained.
- Structural requirements: The regulations regarding supply and exhaust air, sound power levels (particularly in residential areas), and tank positioning must be observed.
Our solutions consider all of these factors, from detailed planning to installation.
energy supply and maintenance
- Emergency power generator: This is usually generated by a diesel generator.
- Combined heat and power plant (CHP): We offer emergency power systems supplied by a CHP plant for larger systems.
- UPS system: As all power generators have a start-up time, a UPS is used to bridge this gap by using accumulators or batteries.
All emergency power systems are serviced at least once a year, with regular functionality tests also carried out.
