Mobile Prefabricated Transformer Substation Product Description
A Mobile prefabricated Transformer Substation usually includes a medium voltage switchgear, a transformer, a low voltage switchgear, and an enclosure. There are usually three compartments in the compact transformer: high voltage compartment, transformer compartment, and low voltage compartment. According to the client's requirement, the transformer can be an oil-type transformer or a dry-type transformer.
Mobile Prefabricated Transformer Substation Product Feature
The equipment is equipped with multiple safety features, including high-voltage fuses, load switches, and lightning arresters. Low-voltage circuit breakers, residual current devices, and relay protection devices effectively prevent accidents such as overload, short circuits, leakage, and lightning strikes. Select models are equipped with an optional intelligent monitoring system. Using sensors and communication modules, these systems enable real-time data collection, remote monitoring, fault alarms, and operational management, enhancing power supply reliability and intelligent operation.

Mobile Prefabricated Transformer Substation Product Feature
Energy-saving and environmentally friendly design
Utilizing low-loss, energy-saving transformer core and winding materials, both no-load and load losses meet national and iec energy-saving standards, effectively reducing operating costs. oil-immersed models utilize environmentally friendly transformer oil, while dry-type models utilize epoxy resin casting. the overall design meets both environmental and energy-saving requirements.
customization capabilities
Compact transformers offer a high degree of customization, including rated capacity, voltage level, housing material, cooling method, inlet and outlet wiring, exterior color, and internal electrical component brands. the structure and functional configuration can be tailored to suit diverse application scenarios, including municipal projects, industrial parks, commercial buildings, and new energy power plants.
Standards and certifications
these products are designed and manufactured in strict accordance with standards such as gb/t 17467 "high-voltage/low-voltage prefabricated substations" and iec 62271-202 "high-voltage/low-voltage prefabricated substations." we can provide authoritative domestic and international certificates and reports, including iso9001 quality system certification, and possess export qualifications and experience.
Service life and maintenance
Under normal operating conditions, compact transformers have a service life of over 20 years, with long maintenance intervals and a low failure rate. routine maintenance, including grounding system inspections, ventilation opening cleaning, and insulation testing, can be performed without disrupting the power supply, significantly reducing o&m costs.
