CRRC 5000 Series Variable Frequency Drive Room

CRRC 5000 series variable frequency drive room is a high-power, integrated power conversion solution tailored for 5000HP 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 5000HP electric fracturing skid systems (including those from baoshi special vehicles) and CRRC’s own CDJD904 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 5000 Series Variable Frequency Drive Room

This 5000 series variable frequency drive room delivers high power capacity with a 3650 kVA phase-shifting transformer capacity and 4000 kVA power module capacity, providing the stable, continuous power required for 5000HP fracturing operations.
It ensures high-precision power regulation via its 36-pulse rectification design and 0~6.6 kV adjustable output voltage, minimizing harmonic distortion and enabling precise speed control for the main motor to optimize energy efficiency.
The drive room features rugged field adaptability through its skid-mounted, fully enclosed cabinet design, which provides excellent protection against dust, sand, and moisture for reliable performance in harsh oilfield conditions.
It enables seamless system integration, as it is designed to pair perfectly with CRRC’s CDJD904 main motors and Baoshi Special Vehicles’ 5000HP fracturing skids, offering a fully integrated “drive room + motor” solution for simplified deployment.
Built on CRRC’s mature drive system technology, it ensures low lifecycle costs with high component commonality and low maintenance requirements, reducing long-term operational expenses and downtime.
