Recently, the prefabricated substation customized by our company for Chongqing Shale Gas Company has been successfully put into operation in the Zu 201 Pressurization and Dehydration Project of Wufeng Formation-Longmaxi Formation Productivity Construction Project at Zu 210H Well Block, Western Chongqing Shale Gas Field. This is the fourth set of prefabricated substations we have delivered to this customer. We keep supplying high-quality power equipment to ensure stable power supply throughout shale gas exploitation, pressurization and dehydration processes, and consolidate solid power support for energy production.

1. Highly Integrated Integrated Intelligent Power Distribution Configuration

The delivered prefabricated substation adopts a modular assembly structure, integrating a complete set of professional power distribution and intelligent management and control systems, including transformers, high and low voltage switchgears, station AC and DC power supply devices, electric energy metering devices and microcomputer integrated automatic protection systems. It is also equipped with emergency lighting, ventilation and air conditioning, video monitoring, fire alarm, special fire-fighting equipment and box intelligent management system.

Relying on the built-in intelligent monitoring system, the equipment can collect real-time operating data of internal devices and monitor environmental and safety conditions, with data synchronized to the background in real time. It realizes unattended operation, remote monitoring and intelligent management, perfectly meeting the operation and maintenance demands of field oil and gas stations.

2. Six Core Advantages Adaptable to Complex Field Working Conditions

01 Rapid Deployment to Shorten Construction Cycle Greatly

Different from the complicated construction procedures of traditional substations, this equipment adopts the mode of factory prefabrication plus on-site assembly, which greatly reduces on-site civil engineering construction and equipment installation workload. While the construction cycle of traditional substations lasts for several months, this prefabricated substation can be put into operation within just a few days after arriving at the site, only requiring foundation pouring and simple cable connection, fully catering to the urgent construction demands of oil and gas projects. Standardized assembly and commissioning in factories strictly control product quality and greatly lower the probability of on-site faults.

02 Compact Structure Suitable for Complex Mountainous Terrain

With high-density integrated layout, its volume is only 1/3 to 1/5 of traditional substations with the same capacity, featuring higher land utilization rate and smaller floor area. Targeting the difficulties of remote mountainous locations, rugged mountain roads and limited transportation conditions of shale gas stations in Sichuan-Chongqing area, we customize and optimize equipment dimensions to fit mountain transportation requirements and achieve easy installation in complex field sites.

03 Cost Reduction and Efficiency Improvement with Excellent Full-cycle Economic Benefits

It boasts prominent advantages in terms of full life-cycle costs. On the one hand, it sharply cuts down early-stage investment in civil engineering materials, on-site construction labor and land acquisition. On the other hand, the equipment features high reliability and stable structure with simple daily operation and maintenance, effectively reducing later maintenance costs and helping enterprises cut expenses and increase benefits in long-term operation.

04 Exquisite Shell Ensures Stable Operation in Harsh Environments

The equipment shell is made of high-quality aluminized zinc steel plate, featuring dustproof, waterproof, anti-corrosion and anti-aging performance with protection grade reaching IP54~IP55. It can stably operate against heavy rain, sandstorm, extreme temperature changes, salt fog corrosion and other harsh field environments. Meanwhile, on-site assembly construction generates less construction waste, dust and noise pollution, balancing project construction and ecological environmental protection.

05 Flexible Application Compatible with Movement and Capacity Expansion

Equipped with special hoisting and moving devices at the bottom, the equipment can be flexibly relocated according to operational needs, ideal for mobile power supply scenarios such as oil and gas exploitation and mine construction. Its modular design supports convenient later capacity expansion. When power consumption rises, there is no need for large-scale reconstruction of existing facilities, and power supply capacity can be upgraded simply by adding modules, conforming to enterprises’ long-term development plans.

06 Intelligent Operation & Maintenance with Dual Safety Protection

Equipped with Siemens S7-200 PLC intelligent control system and high-precision sensors, it collects real-time core operating data including voltage, current and temperature. Users can check equipment status remotely via mobile phones or computers to accurately predict potential safety hazards. The fully insulated and fully sealed structure not only isolates external environmental erosion, but also guarantees personal safety of maintenance staff, building a solid barrier for safe production.

3. Multi-scenario Application Empowering Power Construction in All Industries

Endowed with multiple strengths including rapid deployment, intelligent control, stable safety and strong adaptability, our prefabricated substations are widely applied in shale gas and oil-gas fields, wind and photovoltaic power stations, industrial parks, urban residential communities, new energy charging stations, emergency power supply and other fields, providing integrated, intelligent and low-cost power distribution solutions for various industries.

Every successful delivery from initial cooperation to the fourth equipment handover is a proof of mutual trust. In the future, we will continue to deepen R&D and manufacturing of intelligent power equipment, adhere to strict quality standards and optimize product performance. We will keep providing more professional and reliable power distribution equipment and services for clients in oil-gas energy, industrial infrastructure and other sectors, strive for win-win cooperation and boost high-quality development of the energy industry.
