First, you must know the power requirements of your building. To ensure the proper functioning of your building, you must know the amount of electricity consumed before getting a switchgear cabinet. Consider how large your building is, what types of machines you have, and whether you want to add more in the future. This knowledge can help you select a cabinet able to provide your facility with the power necessary to function as intended.
Then,medium voltage switch gear ensure the cabinet can fit in your building. Your switchgear cabinet will need to fit in the allocated space inside your facility and be accessible for repair work. If the cabinet is too small or difficult to access, replacing it could create problems that are much costlier to resolve.
Rule of thumb: A switchgear cabinet you choose should also ensure that your machines and workers are safe. The cabinet you select should come with elements like temperature regulation, humidity regulation, and safeguard from fire and blasts. These enable you to secure your machines and keep your workers safe. With these safety features in place, you can save your equipment from costly damage and keep your employees safe.
Well,switchgear electrical another essential thing is to select a durable cabinet. You want to purchase a premium-quality cabinet that will serve you for years. Opt for cabinets constructed from durable materials that are tested for durability. Opting for durable switchgear cabinet will save money as you won't be required to repair or replace it frequently.
Finally, seek for a switchgear cabinet that offers a good ratio of value to cost. You want a powerful cabinet that will endure, but you need to consider how much you can afford to spend. Explore the switchgear cabinet as per your requirement and budget-end. However, you will be able to obtain a cabinet that meets your needs at a reasonable rate by striking the ideal equilibrium between quality and affordability.
So when you purchase switchgear cabinet from your building, Keep all these above points in your mind. Evaluate your power requirements, make sure the system is a good fit,lv switchboard safeguard your workers and equipment, select a solution that is tough enough for your needs, and validate how quality correlates with price. Once you have considered these points, you will be in a position to select a switchgear cabinet that can serve your facility well for many years ahead.
Key points for selecting switchgear include
1. Clearly define the project positioning.
High-voltage switchgear is a complete combination product, and its core components are mainly imported. If technical issues arise, equipment maintenance and replacement can be challenging. Therefore, in a sufficiently budgeted situation, it is advisable to choose well-known brands that have sufficient stock and can provide efficient solutions when problems occur.

2. Verify qualifications.
Before making a purchase, request the manufacturer to provide the outline (or requirements) of the switchgear's factory tests. Reputable manufacturers typically have this information available. It is important to ensure that the main components are configured according to the drawings and that specified brands are selected, such as Siemens, Schneider, etc.
3. Cabinet materials.
High-voltage switchgear cabinets are relatively large, and the choice of cabinet materials has a significant impact on the price. Generally, aluminum-zinc plates are used for component brackets, while the door panels are made of high-quality 300 series steel plates.
4. Arrangement of the entire cabinet.
The arrangement and position of the cabinet are crucial considerations for the manufacturer when constructing internal partitions, terminal protection boards, and busbar segment supports. The layout plan should align with the actual positions of incoming and outgoing lines on-site, especially accurately representing the operational face of the cabinet. This ensures smooth installation of the high-voltage cabinet upon arrival at the site. Neglecting this aspect initially can lead to rework when discrepancies are discovered at the site.
5. Incoming and outgoing line methods.
Conventional methods for incoming and outgoing lines on switchgear generally involve two connection options: (1) Cable connections in cable compartments, or (2) Lines passing through the cabinet roof and connected to busbar bridges, which are further linked to overhead lines through wall sleeves. Some users may have cable trays introduced from the cabinet roof, with internal and top connections, along with additional safety net frames. While users provide system diagrams and standard plans when placing orders, it is not always possible to clearly express the incoming and outgoing line methods. Therefore, users should specify the technical agreement based on actual installation requirements at the site to avoid difficulties during installation.
6. Correct selection of circuit breaker breaking capacity.
On the system diagram, the selected circuit breaker should indicate not only the model, rated working voltage, and rated current but also the breaking capacity. When users fail to specify the breaking capacity on their drawings, it creates difficulties for the manufacturing company during engineering design. The selection of breaking capacity should be based on the system's short-circuit parameters. Without a proper understanding of the system's short-circuit parameters, it is challenging for the manufacturer to make the correct selection. Some users blindly choose high breaking capacities without considering the system's short-circuit parameters, resulting in unnecessary financial waste. It is crucial to choose the correct breaking capacity to ensure safe operation while also considering cost reduction of the product.
