Vehicle Mounted Mobile Substation
Vehicle Mounted Mobile Substation
Ningbo Tian'an has developed a prefabricated mobile substation, known as a vehicle-mounted substation, to address both international and domestic needs. This innovation fills a gap in China and was first exported in 2008. The substation is designed for emergency replacement of conventional substations, to support high load periods, and to serve as temporary solutions in areas with increasing electricity demand or interrupted permanent substation plans. Key benefits include ease of transport, complete equipment setup, flexibility, reliability, and cost savings on land and installation.
Technical Parameters
- Main Transformer Capacity: Ranges from 5 to 50 MVA.
- High Voltage (HV) Side: Rated voltage options are 33, 35, 66, 110, 132 kV with rated current options of 630, 1250, 1600, 2000 A and short-circuit breaking current of 25, 31.5, 40 kA.
- Low Voltage (LV) Side: Rated voltage options are 6.6, 11, 13.8, 22, 33, 35 kV with rated current options of 1250, 2000, 2500, 3150 A and short-circuit breaking current of 20, 25, 31.5, 40 kA.
- Rated Frequency: 50/60 Hz.
- Operational Conditions: Ambient temperature from -40 to +60°C, solar radiation up to 1000 W/m², humidity ≤95%, altitude ≤2000 m, and wind speed up to 40 m/s.
- Seismic Conditions: Horizontal acceleration of 0.15 g in general areas and 0.3 g in strong earthquake areas; vertical acceleration of 0.075 g in general areas and 0.15 g in strong earthquake areas.

Catalog excerpts
CZBTD Vehicle Mounted Mobile Substation 1.General Ningbo Tian'an has independently developed a prefabricated mobile substation (hereinafter referred to as a vehicle mounted substation) based on the actual situation both internationally and domestically, filling the gap in China. In 2008, the company exported China's first mobile substation. This substation is mainly used to immediately replace all or part of a conventional substation in emergency situations and restore power supply; It can be put into operation during high load seasons or times to solve the problem of insufficient power supply capacity in a region; In some areas where the demand for electricity is increasing and exceeds the pre layout of power construction, substations can be put into operation as temporary substations to solve the problem of power shortage; And areas where permanent substation construction plans are interrupted due to funding shortages or other reasons. Vehicle mounted substations have the characteristics of convenient transportation, complete equipment, flexibility and reliability, saving the cost of land acquisition, civil engineering and equipment installation, and improving the reliability of power supply in the power system.
