33kv Compact Substation

VKE 33kV compact substation is a prefabricated unit that integrates high-voltage switchgear, distribution transformer and low-voltage switchboard into a single enclosure. Due to its flexibility and reliability, it has become the preferred solution for space-constrained urban and industrial applications.

 

Structure

All components are properly arranged within a limited space. The compact design reduces land usage while maximizing spatial efficiency. In urban areas where land resources are scarce, the 33kV compact substation can easily adapt to narrow sites without causing excessive impact on the surroundings.

 

Convenience

Pre-assembled and tested in our factory, the 33kV compact substation requires minimal on-site setup and commissioning. In newly built residential communities, the substation can be deployed quickly to provide stable power support. The plug-and-play design shortens the construction period and minimizes disruption to residents.

 

Performance

Advanced techniques and high-quality materials ensure that the 33kV compact substation can operate stably in harsh conditions. Studies also highlight this model's reliability when operating under temperature fluctuations, humidity variations and electromagnetic interference.

 

Appearance

The 33kV compact substation features smooth lines that blend harmoniously with the surrounding environment. In image-conscious commercial centers, the substation does not disrupt the overall landscape; instead, it integrates seamlessly and becomes a distinctive feature.

The 33kV compact substation shall be placed at a higher position to prevent rainwater from seeping into the enclosure. When pouring the concrete platform, there should be a gap between the high and low voltage sides to facilitate the laying of incoming and outgoing cables. When excavating the foundation, if garbage or corrosive soil is encountered, it must be dug out until solid ground is reached. Then, backfill with good quality soil, and top with sand-gravel mixture or roadbed material to ensure a stable foundation.

The grounding and neutral connection of the 33kV compact substation share the same grounding grid. The grounding grid typically involves driving grounding stakes at the four corners of the foundation and then connecting them as a whole. The substation must have two reliable connections to the grounding grid. After operation, the grounding connections should be regularly inspected to ensure no loosening or corrosion, and the grounding resistance shall be periodically measured and maintained not to exceed 4Ω.
