1. Introduction to the 1000kVA Transformer Substation:
1000kVA transformer substation is commonly used in residential areas, production workshops, factories, and industrial zones. It is designed to handle power requirements of medium-scale operations.
2. Functions of a 1000kVA Transformer Substation
This substation is part of the power distribution system. Its primary function is to convert voltage levels from high to low or vice versa, depending on system requirements. It helps distribute power from the grid to end users such as residential areas and businesses.
3. Structure of a 1000kVA Transformer Substation
There are different types of 1000kVA substations, each with unique characteristics. However, all substations typically include the following components:
3.1. 1000kVA Transformer
The transformer is a static electromagnetic device that operates based on electromagnetic induction. It transforms alternating current (AC) from one voltage level to another without changing the frequency. The transformer can either increase or decrease voltage depending on its design, and it plays a key role in power transmission and distribution.

3.2. Distribution and Control System
This system includes control cabinets, medium-voltage switchboards, and low-voltage distribution panels.
3.3. Isolator Switch
Isolator switches are used to disconnect circuits, preventing the flow of electricity during emergencies or maintenance. They play a crucial role in ensuring the safety of the electrical system.
3.4. Copper Busbars
Copper busbars serve as intermediaries in power transmission, offering high stability and efficiency. They are typically manufactured in fixed lengths (e.g., 4m) and selected based on installation requirements.
3.5. Grounding and Lightning Protection System
Lightning arresters are devices used to limit voltage surges and protect electrical systems and high-voltage equipment from both direct and indirect lightning strikes.
4. Design Requirements for a 1000kVA Substation
When designing a substation, the following criteria must be met:
-
Power Quality: The substation should be placed at the load center to reduce line length, minimize voltage drop, and reduce power losses.
-
Cost Efficiency: Ensure the investment is reasonable and avoids waste.
-
Safety: Must be safe for personnel and equipment, comply with industrial aesthetics, and ensure electrical corridor clearance. The substation should not negatively impact nearby structures or residents.
-
Operational Convenience: The layout should allow for easy operation and maintenance.
5. Common Types of 1000kVA Substations
5.1. Indoor Substation (1000kVA)
Indoor substations are widely used due to their suitability in densely populated urban areas. With compact dimensions, they can be installed in enclosed spaces, ensuring safety and aesthetics.
5.2. Pad-mounted Substation (1000kVA)
A pad-mounted substation is installed at ground level and is suitable for outdoor environments, especially where space and access need to be optimized.
5.3. Ground Substation (Base Type)
Commonly seen in rural areas, offices, or small factories. High-voltage equipment is mounted on poles, while the transformer (single-phase or three-phase) is installed on a concrete platform. The distribution cabinet is typically housed indoors for protection against oxidation, pests, and rodents.
5.4. Compact Kiosk Substation
This type of substation is ground-mounted and integrates switchgear and transformer components into a sealed metal housing.
It consists of three compartments: medium-voltage, low-voltage, and transformer compartment.
With transformer capacity ranging from 100kVA to 2500kVA and voltage up to 35kV, these units are ideal for industrial parks, residential complexes, and high-rise buildings.
5.5. Single-Pole Substation
In this outdoor type, the transformer is mounted on a single steel or centrifugal concrete pole. Components are made from galvanized or electrostatic powder-coated steel, including the support base, pole body, and baseplate. These substations are suitable for crowded residential areas or medium-capacity factories.

6. Transportation of a 1000kVA Transformer Substation
The transformer must be transported in an upright position—tilting is strictly prohibited. It must be securely fastened to prevent shifting. Do not tie cables or insulation parts. Vintec’s transport vehicles maintain a maximum speed of 30km/h when transporting the equipment.
