Control cabinet and switchgear prefabrication – why is outsourcing a cost-saving solution for your business?

It is therefore no surprise that their manufacture and assembly are tasks for a narrow group of specialists. They require precision, many years of experience and advanced technological facilities. That is why more and more companies are choosing outsourcing, entrusting the prefabrication and assembly of switchgear and control cabinets to external specialists. What are the benefits of this solution, and what exactly is included in such services?

Switchgear and control cabinets – what are they and what functions do they perform?

LV switchgear and MV switchgear are key components of electrical power infrastructure. They are responsible for the safe intake, distribution and delivery of electrical power at low voltage (LV), medium voltage (MV) and, in some applications, higher voltage levels to individual circuits, devices and sections. While switchgear ensures the stable and continuous power supply of the entire plant, the operation of the machines themselves is supervised directly by control systems such as control cabinets.

What is a control cabinet and what is its function in industrial systems?

A control cabinet is responsible for control and protection in industrial systems. Inside, it contains automation components, protective devices and control systems that manage the operation of machinery and installations.

Their versatility and major impact on industrial performance mean that switchgear and control cabinets are used in almost every branch of industry — from power engineering and manufacturing to building automation. Without them, stable, safe and precise control of technological processes would not be possible. In practice, this would mean a lack of control over many machines, installations and even entire production lines.

What does the prefabrication of switchgear, control cabinets and other power distribution and control systems involve?

For a piece of equipment such as switchgear or a control cabinet to perform its function properly, it must be appropriately designed, built and tested. So, what does control cabinet prefabrication involve?

• Manufacture of mechanical components: we produce, among other things, busbars, connectors, laminated components, and parts with galvanic coatings or powder-coated finishes.
• Assembly of electrical apparatus and wiring: precise cable routing and integration of subassemblies.
• Multi-stage acceptance testing: point-to-point connection tests, earthing effectiveness measurements, and high-voltage insulation tests.

Why Electris?

We manufacture up to 70% of the components used inside cabinets in-house. For the remaining items, we provide full procurement support. This gives customers greater confidence in on-time delivery, excellent quality and the long-term reliability of the finished equipment. Our production capabilities also allow for rapid scaling — from single prototypes to OEM series production.

Why does outsourcing the assembly of switchgear and control cabinets pay off? The key benefits

An increasing number of companies are choosing to outsource the prefabrication and assembly of switchgear and control cabinets. This means handing over the entire production process to specialists who are responsible not only for manufacturing the cabinet, but also for its integration, testing and quality control. As a result, the customer receives a ready-made, fully verified solution without having to commit their own technical and production resources.

The main benefits of outsourcing electrical cabinet prefabrication include:

• cost savings – companies do not need to invest in expensive production infrastructure, machinery or specialist personnel, which significantly lowers the entry threshold and operating costs;
• time savings – established technological facilities and experienced engineering teams enable much faster project implementation than building internal resources from scratch;
• higher workmanship quality – the manufacturer’s specialisation and repeatable, controlled processes result in greater assembly precision and a lower risk of errors;
• production flexibility – it is possible to deliver both individual prototypes and medium- or large-scale series without having to reorganise in-house production;
• reduced operational risk – process standardisation, multi-stage quality control and FAT testing reduce the risk of failures and technical non-conformities;
• process optimisation within the company – the customer’s team can focus on product development and sales instead of logistics and production.

In practice, outsourcing the prefabrication and assembly of switchgear or control cabinets is an investment in peace of mind — customers gain confidence that the entire process is under the control of specialists.

What does the switchgear production process at Electris look like? From documentation analysis to a finished system

At Electris, we provide a comprehensive assembly service for LV and MV switchgear and control cabinets. We begin with a detailed analysis of the customer’s technical documentation from a functional, production and assembly perspective.

We then move on to the prefabrication stage, which includes manufacturing selected components, procuring the remaining parts, and integrating all cabinet elements — from mechanical parts and wiring through to control systems. The entire process takes place in controlled production conditions, which ensures repeatability and a high standard of workmanship.

The next step is to verify the correct operation of all subassemblies and carry out multi-stage quality and safety testing of the complete unit.

What do you gain by choosing Electris as your partner in control and power distribution systems?

• Quality assurance – full compliance with technical documentation.
• Everything under one roof – in-house production of mechanical components increases speed and flexibility.
• Reliability – multi-stage quality control and rigorous FAT acceptance testing.
• Savings and optimisation – engineering support in improving and refining your designs.
• Security of supply – careful attention to proper protection and transport.
