The 10kV 160kVA-1250kVA Prefabricated Compact Electrical Substation is a modern, efficient, and reliable solution for power distribution. Designed with advanced technology and robust construction, it is suitable for various applications in industrial, commercial, and residential settings.
The 10kV Compact Electrical Substation is ideal for use in urban and rural distribution networks, industrial facilities, renewable energy systems, and infrastructure projects requiring efficient and dependable power delivery.
The 10kV 160kVA-1250kVA Prefabricated Compact Electrical Substation combines advanced engineering with compact design to deliver reliable and efficient power distribution. Its versatile configurations and compliance with international standards make it a top choice for diverse energy needs.

Box-type substation is also called prefabricated substation. It combines high-voltage switchgear, distribution transformers and low-voltage power distribution devices into a single factory prefabricated indoor and outdoor compact power distribution equipment according to a certain wiring scheme, which organically combines functions such as transformer step-down and low-voltage power distribution. Installed in a moisture-proof, rust-proof, dust-proof, rat-proof, fire-proof, anti-theft, heat-insulation, fully-enclosed, and movable steel structure box. Box-type substations are divided into European-style box-type substations, American-type box-type substations, and underground box-type substations.
Products Description
YBD Buried Type Box Substation
Buried box-type substation is mainly composed of buried transformer and outdoor switchgear of advertising light box. The buried transformer is a new type of compact substation equipment composed of a transformer, a high-voltage load switch, a fuse, etc., which is installed in a pit, does not occupy the surface space, and can be submerged in water for a period of time. The outdoor switchgear of advertising light box is a hybrid structure integrating billboards and outdoor switchgear, and is installed on the ground.The inside of the box is an outdoor high and low voltage power distribution cabinet, and both sides are advertising light boxes, which have excellent visual effects. The fully buried type is also called an underground substation. Its box has excellent anti-corrosion and compression resistance, and has absolute air tightness.
1.It can greatly save land, without land acquisition and civil construction, and save infrastructure investment.2.There are no obstacles on the ground, which does not affect the environment, and does not affect people's vision and scenery.3.The fully buried type installed on the lawn and green belt can also be designed with some decorative ornaments on the ground, such as sculptures, rockery, etc.; if the ground requires no obstacles (including ventilation ducts), you can choose a square type prefabricated substation. 4.The power distribution equipment of the fully buried prefabricated substation is set underground, which is safe and reliable.5.The ground is not affected by transformer noise.6.As the underground is relatively shady and cool, the temperature rise of the transformer is relatively stable during operation.7.The internal space of the fully buried prefabricated substation is relatively spacious, and the maintenance operation will not cause interference on the ground, and will not interfere with the surrounding environment.
Transformer:S series of oil immersed transformer.
