Pure
Power quality
Filtering harmonics, compensating reactive power and holding voltage through a sag. The result is measured at the point of common coupling, not in a brochure.
About Tranpure
We make power pure. Then we make it green.
Tranpure is the combination of transfer and pure: the power electronics that convert and store energy, and the grid engineering that keeps it clean. Both are needed before solar and storage can replace anything.
The name
Make power pure. Make it green.
Founder, Beijing Tranpure Technology
The name is the brief.
Tran stands for transfer, transform and transition — the conversion and storage side of the business. Pure stands for clean power in both senses: harmonics removed and reactive power compensated, and generation shifted from diesel to sunlight.
That combination is not a positioning exercise. A factory that loses a production line to a voltage sag and a mine that burns diesel around the clock have the same underlying problem: power that is neither clean nor green. Fixing it needs the power electronics and the grid engineering in one design.
Tranpure builds both: storage and PV on one side, active harmonic filters, static var generators and voltage-sag mitigation on the other, with one engineering team responsible for the interfaces.
Pure · Green · Power
Three words, three parts of the business.
The slogan is not decorative. Each word maps to a product line and to a measurable result on site.
Green
Solar + storage
PV and batteries replacing diesel hours and grid peaks. The result is measured in fuel not burned and energy moved out of the peak tariff.
Power
Conversion & storage
PCS, DC/DC, switchgear and controls converting, transferring and storing energy. The result is a system that behaves as specified at the point of connection.
Capabilities
What we do in-house.
A project passes through six disciplines, most of them under one roof; the last is on site with you at commissioning.
Electrical engineering
Single-line diagrams, protection coordination, cable and switchgear sizing, short-circuit and harmonic studies for the point of connection.
Power electronics
PCS, DC/DC and AHF/SVG design and matching. Control loops are tuned on the test bench against the load they will see.
Controls and software
EMS and SCADA, Modbus and IEC 61850 interfaces, dispatch logic, remote monitoring and alarm forwarding.
Thermal and structural
Container layout, HVAC or liquid cooling, fire detection and suppression, transport and lifting design for the site.
Manufacturing and test
Assembly, wiring, functional test and burn-in, followed by a factory acceptance test the customer can witness.
Field commissioning
Installation supervision, commissioning, grid-operator witnessing and operator training, with as-built documentation.
Quality & compliance
Evidence, not assurances.
A storage system is a collection of interfaces. Quality means every interface was inspected, tested and written down before the container was closed.
- Incoming inspection and batch traceability. Cells, PCS, breakers and filters are recorded by batch. A failed batch is quarantined, not worked into another project.
- Factory acceptance test. Each system runs against the approved test plan before shipment, and the customer can attend.
- Documentation package. Drawings, test reports, protection settings, O&M manuals and the spare-parts list are handed over as one set.
- Certification evidence. Certificates and test reports for the configured product are supplied with the proposal. The public certificate list is being verified and is not published yet.

How we write and build
Three rules we apply to copy and to hardware.
01
Specific over superlative
If we cannot name the mechanism, it does not go in the text. “Filters the harmonic orders measured at your incomer” instead of “improves power quality”.
02
One system, not five boxes
Projects fail in the interfaces between PCS, transformer, filters and controls. We design and test those interfaces together, under one contract.
03
Documented, not promised
Assumptions, protection settings and test results are written down and handed over. A figure that is not verified stays out of the proposal.
Bring us the site, not the shopping list.
Tell us where it is, what the load does and where the power quality hurts. We will start from that and work back to the equipment.
