1000kva 33KV compact substation

GE Transformer has an advanced design concept, elegant appearance, and optimized size, which is only 1/3 of the substation with the same capacity. The cabinet is built with the latest domestic technology and craftsmanship and has excellent moisture-proof, rust-proof, dust-proof, rodent-proof, fire-proof, theft-proof, and heat-insulating properties. Fully enclosed mobile, especially suitable for urban network construction and renovation, as well as mines, factories, enterprises, oil and gas fields, wind power stations, and other places.

2. The power supply provided by the equipment is both safe and reliable. It offers excellent mechanical and electrical interlocking, fulfilling the “five defenses” requirements. The equipment can be deployed deep into the middle voltage load center, reducing network losses and enhancing power supply quality.
3. The equipment meets the demands of modern urban cable entry projects and can be repurposed in different locations after initial usage. This eliminates the need for repeated investments.
4. The equipment helps save money and manpower due to its cost-effectiveness and quick results. It eliminates the need for infrastructure investments and reduces on-duty personnel requirements. The equipment also boasts extended maintenance intervals, improving the reliability of safe operations.
5. The box shell is designed with various materials and a beautiful appearance, ensuring a reliable power supply in different environments. The color of the box-type substation shell can be customized to easily coordinate with the surrounding environment. This makes it particularly suitable for urban construction projects.
6. Each functional unit in the prefabricated substation is independent, allowing for customization and providing a wide selection range. This enhances its market adaptability and versatility.
   Prefabricated compact substation structure and components:
   The products are mainly divided into three parts: high-voltage switch room, transformer room, and low-voltage switch room. For added convenience, the three parts can be shipped separately.

Low voltage room
A compact, easy-to-replace new molded case circuit breaker is used for incoming and outgoing lines. And it adopts an advanced multifunctional intelligent comprehensive protection controller and comprehensive reactive power compensation device.

Transformer room
Prefabricated compact substations can choose oil-immersed transformers and cast resin dry-type transformers. If there is no special requirement, our customers usually use oil-immersed transformers in prefabricated compact substations because the price is cheaper than dry-type transformers.

Internal connection
GE Transformer uses solid insulated cable accessories to connect transformers and solid-state switches. These accessories ensure safe, reliable, and fully insulated connections.

The shell of the compact substation
Mainly made of steel structure, and the four sides can use composite sandwich panels, stainless steel panels, cold-rolled panels, stainless steel panels inlaid with anti-corrosion wood, concrete walls, etc. according to different use environments, so as to coordinate with the environment. In addition, the steel plate structure has undergone special anti-corrosion treatment, which has strong corrosion resistance and mechanical durability

In order to ensure proper temperature regulation, the product adopts a unique large circulation heat dissipation design. Each chamber is individually sealed to prevent heat exchange between the compartments.

Our prefabricated substation is easy to install and can be installed indoors directly without additional building foundations. This not only saves costs but also optimizes space utilization.
