Background: Powering the Tarim Oilfield Core Zone
Luntai County sits at the heart of the Tarim Basin in southern Xinjiang — China’s largest oil and gas producing region by reserve volume and a strategic priority for national energy security. With oil and gas extraction operations running continuously alongside an expanding portfolio of photovoltaic grid-connection projects and industrial facilities, reliable medium-voltage power infrastructure is essential to every aspect of field operations.
This delivery comprises three complete prefabricated box-type substations for the Beijing DM Oilfield High-Tech Co.,Ltd. Luntai base — a supporting infrastructure project within PetroChina’s broader Tarim field development. Each substation provides a self-contained, fully integrated power distribution unit: stepping down from the 35kV main grid to 10kV via an oil-immersed transformer, then from 10kV to 0.4kV via a dry-type transformer, ready for direct connection to oilfield production equipment, photovoltaic inverters, or industrial loads.
Equipment Specification
Each substation unit contains:
LV Transformer — SCB14-2500/10 Dry-Type
| Parameter | Value |
| Model | SCB14-2500/10 |
| Rated Capacity | 2,500 kVA |
| Voltage | 10kV / 0.4kV |
| Energy Efficiency | Grade 2 (GB 20052-2024) |
| Insulation | Epoxy cast resin |
HV Transformer — Oil-Immersed 35kV/10kV
| Parameter | Value |
| Rated Capacity | 2,500 kVA |
| Voltage | 35kV / 10kV |
| Energy Efficiency | Grade 2 (GB 20052-2024) |
| Type | Oil-immersed, ONAN |
Environmental & Protection Specifications
| Parameter | Value |
| Enclosure Protection | IP54 |
| Seismic Design | Grade 9 fortification |
| Operating Temperature | -30°C to +55°C |
| Dust & Sand Protection | Suitable for Xinjiang desert conditions |
The IP54 rating and Grade 9 seismic design directly address Luntai County’s two most demanding environmental challenges: pervasive windblown sand and dust from the Taklamakan Desert, and the seismic activity of the Tarim Basin geological zone. The -30°C to +55°C operating range covers the extreme diurnal and seasonal temperature variation characteristic of Xinjiang’s continental climate — from deep winter nights to peak summer afternoons.
Dispatch



All three substations departed on April 17, 2026, travelling overland from Zhongxin General’s Sichuan production facility to Luntai County, Xinjiang — a route of approximately 3,000 km through western China to the Tarim oilfield core zone.
