Case

Project Overview

This project focuses on the temporary transformer installation for the Automobile City Engineering Project located in Longwan District, Wenzhou City, Zhejiang Province, China. As a key regional construction initiative, the project requires stable and reliable temporary power supply to support various on-site construction activities, including foundation excavation, steel structure installation, concrete pouring, and mechanical operation during the whole construction period.

Project Background

The Automobile City Engineering Project covers a large construction area with numerous large-scale construction machinery and electrical equipment. To meet the real-time power demand of on-site construction and ensure the smooth progress of the project, the construction team formulated a specialized temporary transformer installation plan in strict accordance with national electrical safety standards and construction site management regulations. The temporary transformer serves as the core power supply facility, providing a safe and stable power guarantee for all on-site engineering operations.

Installation Implementation

1. Site Selection and Foundation TreatmentThe installation site was scientifically selected on the flat and solid ground of the construction site, far away from excavation areas and potential safety hazards. The construction team carried out professional foundation treatment, including foundation leveling, concrete pouring, and reinforcement, to ensure the stability and load-bearing capacity of the transformer foundation.
2. Equipment Selection and TransportationAccording to the calculated power load of the construction site, suitable capacity and model of temporary transformers and supporting electrical equipment (such as high-voltage cabinets, low-voltage distribution boxes, and cables) were selected. All equipment was transported to the site by professional transport vehicles under strict safety protection to avoid damage during transportation.
3. **On-Site Installation and CommissioningProfessional electrical construction personnel conducted the installation work in accordance with the construction drawings and operating procedures, including transformer hoisting, high-voltage and low-voltage cable connection, grounding system installation, and equipment fixing. After the installation was completed, the commissioning and testing of the transformer and the entire power distribution system were carried out, including voltage detection, insulation resistance test, and no-load test, to ensure the normal operation of the equipment.
4. **Safety Protection and ManagementComplete safety protection facilities were set up around the temporary transformer, including protective fences, warning signs, and lightning protection devices. A special on-site management system was formulated, assigning special personnel to be responsible for the daily inspection and maintenance of the transformer to eliminate potential electrical safety hazards in a timely manner.

Project Significance

The successful completion of the temporary transformer installation has effectively solved the power supply problem of the Automobile City Engineering Project in Longwan District, Wenzhou. It ensures the efficient and safe operation of various construction machinery and equipment, shortens the construction period, and provides a solid power support for the smooth implementation of the entire project. This temporary transformer installation practice also provides a valuable reference for power supply guarantee in similar large-scale engineering construction sites.
