V. 35kv Mobile Substation FAQ
Q1: What are the core components of a 35kV vehicle mounted mobile substation?
Our 35kV units consist of a 35kV GIS/HGIS high-voltage switchgear, a specialized mobile power transformer, intelligent protection and control cabinets, fire suppression systems, and a heavy-duty modular trailer or container carrier.
Q2: What are the typical application scenarios for 35kV mobile substations?
They are widely used for load transfer during urban grid renovations, providing temporary power for large-scale industrial or metallurgical projects, rapid power reconstruction following natural disasters (within 72 hours), and supporting infrastructure for Belt and Road international projects.
Q3: What are the advantages of 35kV mobile substations compared to fixed substations?
Mobile substations offer significantly faster deployment, taking only 3 to 7 days compared to the 12 to 24 months required for fixed sites. Financially, they require a much lower initial investment—typically between RMB 8-20 million, whereas fixed substations can exceed RMB 50 million. Additionally, mobile units require minimal land prep and no permanent land acquisition, and they boast a high reuse rate, allowing them to be redeployed at multiple different locations over their lifespan.
Q4: What are the special requirements for the transportation and deployment of 35kV mobile units?
Transportation requires hydraulic axle trucks with a total weight capacity of up to 80 t. All equipment complies with ISO 1496 international freight standards. For deployment, the site foundation must have a bearing capacity of ≥ 150kPa and an inclination of less than 0.5 degrees.
Q5: How long does it take to put a 35kV mobile substation into operation?
Under regular conditions, deployment including debugging takes 3 to 7 days. In urgent emergency modes, the unit can be operational in as little as 48 hours, provided it has been pre-installed and debugged.
Q6: What are the functions of the 35kV intelligent monitoring system?
The system provides real-time monitoring including DGA online oil chromatography and hot-spot temperature alerts (accuracy ± 1℃). It fully supports IEC61850 communication protocols for remote access and integrates seamlessly with standard SCADA systems.
