Solutions

We are more than just an equipment manufacturer; we are dedicated to providing specialized end-to-end solutions for EPC contractors, industrial developers, and public infrastructure projects.

Custom Transformer Engineering

Delivering bespoke designs tailored to specific voltage requirements, extreme climate resilience (for African grids), and high-efficiency industrial upgrades (for the North American market).

Charging Infrastructure Solutions

Providing comprehensive turnkey solutions for charging station construction, deeply integrating highly reliable transformers with intelligent power distribution systems to empower the future of mobility.

Residential Energy Storage Solutions

Combining LiFePO4 batteries, single-phase solar inverters, and integrated backup systems for household solar self-consumption and resilient home power.

Industrial, Commercial, and Infrastructure Hubs

Providing robust power distribution architectures for manufacturing plants, mining operations, and modern urban infrastructure.

Start with network and insulation data

State the nominal system voltage, highest voltage for equipment, insulation level, primary and secondary ratio, frequency, phase, vector group, neutral arrangement and fault level. These inputs determine more than the 20 kV product label and should be aligned with the local utility or project specification.

Define load duty and capacity

The present page does not establish a verified capacity range. Describe continuous and peak load, diversity, motor starting, harmonic sources, renewable interfaces, overload requirements and future expansion. The proposed kVA and thermal margin must be confirmed in the quotation and technical schedule.

Review sealed construction as a complete system

Evaluate tank construction, oil filling, pressure behavior, temperature indication, tap arrangement, bushings, terminals and maintenance access together. A sealed design should not be presented as universally maintenance-free, leak-proof or suitable for every environment without model evidence.

Set measurable performance requirements

Provide permitted no-load loss, load loss, impedance, temperature rise and noise. Ask the supplier to state the cooling method and guaranteed figures for the offered rating. The database material field lists Copper/Aluminum, but the actual conductor or winding material and any available selection must be tied to the quoted design and documented performance.

Coordinate protection and installation

Share upstream and downstream protection, cable sizes, surge-protection requirements, foundation, clearances, cable entry and earthing arrangement. Also declare ambient temperature, altitude, dust, humidity and corrosion exposure so accessories and enclosure treatment can be reviewed.

Control standards and test claims

IEC 60076 appears in the database record, but this does not establish certification or full compliance. Specify the standard edition, routine, type or special tests, witness requirements and report list. Each claim must be checked against the selected rating and document scope.

Build the 20 kV enquiry package

Send the electrical schedule, single-line diagram, load profile, loss limits, taps, winding preference, accessories, environment, tests, quantity and destination. A complete enquiry allows the response to separate confirmed data from items still requiring engineering review.

Frequently Asked Questions

No. The page identifies the voltage class, but primary and secondary voltage, highest equipment voltage, insulation level and connection must be confirmed for the project.

The current record lists capacity as custom without an approved range. Provide the required kVA, load profile and future growth so the available model can be confirmed.

No such blanket claim should be made. Maintenance depends on the tank, oil system, accessories, site conditions and the manufacturer’s approved instructions for the quoted model.

Request the datasheet, loss and impedance schedule, drawings, nameplate data, accessory list, test plan and reports showing the model, rating, standard edition and covered tests.

Outdoor use depends on the complete design, accessories, coating and declared site conditions. Provide ambient, altitude, dust, rainfall, corrosion exposure and installation details for review.
