V. 220kv Mobile Substation FAQ
Q1: What are the core components of a 220kV vehicle mounted mobile substation?
High voltage unit: 220kV GIS (Gas Insulated Switchgear)
Auxiliary systems: intelligent protection control cabinet, fire protection, and redundant cooling systems
Structural carrier: Multi-module hydraulic trailers (Goldhofer-compatible design)
Q2: What are the typical application scenarios of 220kV mobile substations?
National Grid: Temporary bypass during 220kV substation major maintenance
Large-scale Energy: Power supply for mega-scale mining or petrochemical hubs
Disaster Relief: High-capacity power restoration for provincial-level grid nodes
Overseas Projects: Fast-track infrastructure for "Belt and Road" energy projects
Q3: What are the advantages of 220kV mobile substations compared to fixed substations?
The 220kV mobile substation offers significant advantages over traditional fixed infrastructure in four key areas:
Speed of Deployment: While a traditional fixed substation takes 24 to 48 months to complete, our mobile units can be operational in just 15 to 30 days.
Investment Efficiency: It eliminates the massive civil engineering and land acquisition costs associated with permanent structures, making it a more cost-effective choice for short-to-medium-term needs.
Flexible Land Use: Unlike fixed sites that require permanent land rights, mobile units occupy a minimal temporary footprint and can be moved once the project is finished.
Asset Mobility: Our mobile units are 100% relocatable and can be reused for 5 to 8 different projects, whereas a traditional substation is a sunken cost that cannot be moved.
Q4: What are the special requirements for the transportation and deployment of 220kV mobile substations?
Highway transportation: Specialized heavy-haulage permits and hydraulic axle trailers are mandatory due to weight and height.
Shipping standard: Specialized Break-Bulk or Flat Rack shipping for ultra-heavy modules.
Positioning requirements: Foundation bearing capacity ≥ 200kPa, inclination < 0.5°.
Q5: How long does it take for a 220kV mobile substation to be put into operation?
Regular deployment: 15-30 days (including assembly of modular units and HV testing).
Emergency mode: Pre-configured modular sets can significantly reduce onsite assembly time.
Q6: Function of intelligent monitoring system for 220kV mobile substation
Real time monitoring: Advanced DGA (Dissolved Gas Analysis) and partial discharge monitoring.
Warning function: Multi-point hot spot temperature limit alarms.
Remote access: Full IEC61850 and SCADA integration.
