CRRC 7000 Series Variable Frequency Drive Room

CRRC 7000 series variable frequency drive room is a high-power, integrated power conversion solution tailored for 7000HP electric fracturing skid systems, delivering a phase-shifting transformer capacity of 3650 kVA, a 10 kV input voltage, and a 0~6.6 kV adjustable output voltage, featuring a 36-pulse rectification design and 4000 kVA power module capacity.
Equipped with a max continuous output current of 2 × 350 A, this drive room is engineered to deliver robust, consistent power conversion under the high-load, continuous operating conditions of oilfield fracturing operations, while its skid-mounted, fully enclosed design ensures reliable operation in harsh, dusty field environments.
As a mature model in the CRRC oilfield drive series, it integrates seamlessly with mainstream 7000HP electric fracturing skid systems (including those from baoshi special vehicles) and CRRC’s own CDJD903 main motors, ensuring reliable operation and compatibility with industry-standard oilfield equipment.
We offer comprehensive life-cycle support for the variable frequency drive room, covering equipment supply, on-site installation and commissioning, maintenance training, spare parts provision, and ongoing technical troubleshooting services.

Advantages of CRRC 7000 Series Variable Frequency Drive Room

With a 3650 kVA phase-shifting transformer capacity and 4000 kVA power module capacity, it delivers the massive power required for 7000HP fracturing operations, ensuring stable and continuous power conversion.
The 36-pulse rectification design and 0~6.6 kV adjustable output voltage ensure low harmonic distortion and precise speed control for the main motor, optimizing energy efficiency and reducing equipment wear.
The skid-mounted, fully enclosed cabinet design provides excellent protection against dust, sand, and moisture, ensuring reliable performance in the harsh conditions of oilfield operations.
Designed to pair perfectly with CRRC’s CDJD903 main motors and Baoshi Special Vehicles’ 7000HP fracturing skids, it offers a fully integrated “drive room + motor” solution for simplified deployment and operation.
Built on CRRC’s mature drive system technology, it features high component commonality and low maintenance requirements, reducing long-term operational expenses and downtime.
