Control cabinet manufacturing for energy supply

Carefully designed and documented low-voltage switchgear and controlgear assemblies for distribution, control, emergency power and energy-related infrastructure.

What is decisive for switchgear assemblies in energy supply?

For low-voltage switchgear and controlgear assemblies, the electrical design determines operational safety: supply system type, short-circuit withstand strength, selectivity, protection concept and thermal behaviour must match and be verified. In addition, there are metering, communication and remote reading, as well as the evidence the operator needs for acceptance and operation. The specific scope results from the supply data, installation site and operator requirements.

Applications

Distribution systems, load management and emergency power systems

Critical

Selectivity, short-circuit withstand strength and temperature rise

Basis

Supply system type, short-circuit data and installation conditions

Requirements

What matters in your industry

Electrical design

Consider rated currents, short-circuit withstand strength, protective and switching devices, and temperature rise on a project-specific basis.

Availability

Define redundancy, reserves, maintainability and spare parts strategy according to criticality.

Metering & communication

Provide for energy metering, power quality monitoring and connection to control or building management systems.

Verification documents

Provide design and routine verifications, test reports and marking to the agreed extent.

Process

How your solution is created

In energy supply, the decisive work happens in the design: supply system type, short-circuit data, selectivity and thermal behaviour must match and be verified before an enclosure is ordered.

Only once these fundamentals are in place do design engineering and manufacturing begin. Testing concludes with the evidence the operator needs for acceptance and operation – each step can be ordered individually.

Requirements

Clarify specification, interfaces, environment and standards.

Engineering

Prepare design, documentation and approval.

Manufacturing

Machine, assemble, wire and label.

Testing

Test, document and hand over for integration.

Planning and documentation

Manufacturing and acceptance

Application and enquiry

Services from a single source

From planning to tested handover

Planning & Engineering

Technical clarification, design and engineering, schematic design, selection of components and interfaces.

Manufacturing

Mechanical machining, assembly and component mounting, professional wiring and cable assembly.

Testing & Quality Assurance

Visual, wiring and functional tests as well as project-specific measurements and traceable test reports.

Manufacturing Models

Matched to quantity and project status

Regardless of the industry, quantity determines how manufacturing is organised. These four models can also be combined within a single project.

One-off Production & Prototyping

One-off units, samples and first builds with short lead times and a high degree of flexibility for changes.

Series Production & Assemblies

Repeatable production based on a frozen documentation status with a consistent testing system.

Contract Manufacturing

Manufacturing to customer-supplied documents, with partially or fully customer-supplied material.

Retrofit & Modernisation

Converting existing systems to available technology when components have been discontinued.

Frequently asked questions

Questions about control cabinet manufacturing for energy supply

Do you also handle design and schematic design?

Yes, Planning & Engineering can be commissioned from technical clarification through to manufacturing documents and electrical documentation.

Are one-off units and series both possible?

Yes. One-off production and prototyping as well as series production and assemblies are separate manufacturing models and can be combined.

Which tests are carried out?

The binding scope of testing is defined in the test plan depending on product, target market and standards, and is documented.

Can specified components and standards be taken into account?

Yes. Approved parts lists, preferred manufacturers, labelling and plant standards are adopted on a project basis, provided they are supplied in full.

What information is needed for a quotation?

Function or specification, place of use and ambient conditions, existing documents, requirements for components and testing, as well as quantity and schedule. We clarify any missing information in the initial meeting.

Can Gross Schaltschrankbau modernise existing systems?

Yes. Retrofit and modernisation is a manufacturing model in its own right – for example when components have been discontinued or an existing system has to meet new requirements. It is based on a survey of the existing status.
