Manufacturing of Electrical Switchgear Equipment

Ensuring the efficient and safe distribution of electricity is the main function of electrical switchgear equipment. To implement it, protective devices are installed inside the enclosure. They minimize the risk of short circuits, overloads and other situations with emergency consequences.

Custom manufacturing of electrical panels is one of the areas of work of LK-Energy. We are one of the leading manufacturers in Ukraine and offer only reliable solutions. Our electrical switchgear equipment ensures the performance of several functions:

• protection of equipment and ensuring the safety of workers;
• control and monitoring of electricity consumption;
• automation of processes;
• control of the operation of devices in the electrical network;
• protection against operational failures (short circuit, overload, etc.).

But the main purpose is the distribution of electricity to various devices, as well as to end consumers.

Importance of using electrical panels

The use of electrical panels from LK-Energy is important for ensuring stable and safe operation of equipment in the network. Custom-made electrical panels are the main components of electrical systems, providing protection against emergency situations (in particular short circuits and overloads).

Thus, the installations are the guarantee of reliable electricity supply at facilities. Thanks to the implementation of modern technologies, such as automation and remote-access monitoring, electrical panels become even more reliable and convenient to manage.

Field of application of switchgear equipment

Switchgear equipment is used in many areas, including the power industry, construction, electrical engineering and various types of industry. In electrical engineering, it is used to distribute electricity and protect against voltage surges.

This helps to establish a stable power supply in offices, in buildings and in industrial structures. But the main field for which the production of switchgear electrical equipment is important is the power industry. In this case, the equipment performs two main functions: control and management of power and energy-saving systems.

What does the design of an electrical panel consist of?

Electrical panels consist of several components:

1. Enclosure. It is a container made of durable plastic or metal. It is intended to protect the contents from the influence of external factors and to ensure safe operation.
2. Relays and contactors. The devices automate processes and regulate the load.
3. Fuses. Parts that prevent accidents from occurring. They protect the system from failures that can occur due to the action of various factors.
4. Circuit breakers. They trip in the event of short circuits or overload.

The design also provides for the presence of measuring devices. They are used to monitor the parameters of the electrical network, such as voltage, current and power.

Manufacturing of switchgear equipment: types of electrical panels

We manufacture several types of electrical panels. Each model is intended for specific conditions and certain functions:

• Metering electrical panel. Used for monitoring and calculating network parameters.
• Control panel. Used to control and monitor devices.
• Automatic electrical panel. They perform the function of protection against emergency situations and failures. They are equipped with circuit breakers.
• Distribution panel. The main function of the equipment is the distribution of electrical energy to various consumers.

There are also specialized panels adapted for specific industries or the special requirements of the facility.

Manufacturing of electrical switchgear equipment: stages of production

Electrical switchgear equipment is produced in several stages. The first stage — design — includes the development of sketches and technical drawings taking into account the customer’s requirements and safety standards. Then the materials and components are prepared.

Custom manufacturing of electrical panels is a process performed in various ways. Among them are guillotine cutting, bending, forming, and the CNC turret-punching method. Next, the components are assembled. Contactors, fuses, switches and relays are installed in accordance with the developed drawings.

After assembly, the QC stage is carried out — testing of the electrical panel. It is checked how well it meets the safety requirements and whether it operates correctly.

During the process, the electrical connections are checked. Another stage is checking the protection system against overload and other failures. After successfully passing all tests, the electrical panel is ready for installation at the facility.

What materials and components are used for the custom manufacturing of electrical panels?

When manufacturing electrical cabinets, we use durable and corrosion-resistant materials:

• cold-rolled galvanized steel (the zinc coating thickness is 275 g/m²);
• stainless steel;
• black metal (painted using the powder furnace-baking method).

In addition, we offer the manufacture of combined-type electrical cabinets, for which two types of materials are used. The configuration of each model includes switches, fuses, contactors, relays, as well as status indicators and status sensors.

Switchgear equipment from the manufacturer: how do assembly and installation take place?

Assembly and installation of switchgear equipment usually begin with preparing the panel enclosure and fastening the mounting rails for attaching the components. Then the main elements are installed. These include contactors, relays, fuses and various types of switches.

Manufacturing of electrical switchgear equipment is performed in accordance with the design documents. Busbar runs and wiring are installed, and the components of the power and control circuits are connected.

After the installation and connection of all components, a check is carried out for correct functioning and compliance with electrical safety. Finally, the electrical panel is closed, and marking is applied to the surface. It is needed to designate the elements of the design and to ensure ease of maintenance.
