If you are looking for transformers suppliers in Southern Africa, you may have googled the words “Reliable Transformers ownership transition after 2021” — possibly to analyze potential suppliers for a tender, to know who is behind the warranty, or to understand how a supplier you are buying from for many years has changed its structure. This expression contains a real question (who is the owner of Reliable Transformers today?) combined with a very specific statement (something serious happened after 2021). This article describes the history of the company, draws the line between proved facts and gaps in the public knowledge, and clarifies what really happened to Reliable Transformers after 2021.
In brief, Reliable Transformers (Pty) Ltd is a South African transformer manufacturing company established by engineer H.J. van Zyl in 1982, located in Benoni South in Gauteng. In 1997, management and ownership of the company moved to the founder’s child, Andre van Zyl, who continues to be the CEO and owner of the firm at present. Information available to the public does not indicate the occurrence of any external takeover or investment in the company, while the available data on the firm illustrates that it has reorganized its operations as the member of “Reltrans group of companies,” expanded its manufacturing floor space in the last five years, increased its production capacity from 6.5 MVA, as well as raised its labor force from about 35 workers in 2023 to approximately 49 by 2026. Just like other private companies of South Africa, the detailed ownership structure of Reliable Transformers (Pty) Ltd is not available publicly, while the verification of directors of the firm has been conducted based on data from records of CIPC.
Who is Reliable Transformers?
Reliable Transformers is a well-known, specialized manufacturer of transformers in South Africa. It is a family-operated business that has been in the industry since 1982, designing and constructing its transformers, inductors, and reactors. Reliable Transformers produces customized products as a manufacturer and not as a trader; thus, it designs, produces, and tests transformers at its own facility.

The ownership history: two generations, one family
The ownership of Reliable Transformers is based on all the characteristics that define a second-generation transition. The following milestones are significant in the lifecycle of the company:
- 1982: Founded in Boksburg by design engineer H.J. van Zyl to design transformers, which were only meant for use in the gold, platinum, and coal mining industries and helped the company capitalise on its bespoke nature.
- 1997: Leadership was passed to the founder’s son Andre van Zyl, an engineer who had previously worked for Eskom and had good software-related skills.
- 2016-2017: The company created its first inverter duty transformer in the solar energy market (2016) and began expansion increasing its manufacturing capabilities by more than twice (2017).
- 2019: A new custom-built facility was opened in Benoni South (around 4,000 m²) as of June 2019. Engineering News stated that the company is “managed by Andre van Zyl and Sesa Pillay,” with a bright prospect for development.
- 2020s to today: Andre van Zyl is still in charge of the company as a CEO and is mentioned as an owner in the latest business directories. The company presents itself as “a member of the Reltrans group of companies.”
The knowledge of this transfer taking place in 1997 is crucial for understanding why the name van Zyl is so frequently mentioned and why the question of ownership of this company should rather be interpreted as the question of ownership of the van Zyl family and their partners.
The “after 2021” question: what the claim actually refers to
According to the research findings, a considerable portion of the populace assumes that Reliable Transformers have altered their ownership status from 2021 onwards. However, an analysis of public documents – including the firm’s public communication, trade articles from South Africa, as well as business references – indicates that that there is no truth in this assumption. In fact, the documentation verifies that there was no announcement of the sale of the company, acquisition of other stakeholders, or insider transactions.What causes confusion is a number of occasions that have occurred at the same time:
- The restructuring of the Reltrans corporations. At some point after 2021, the company began using the word “group” when referring to itself, making people think there have been changes in the ownership.
- Misunderstanding of the new terminology related to the definition of corporation. This is because older publications and search requests still use the term “Reliable Transformers CC” that was applicable in the past, prior to the changes of the business.
- Progressive improvement in the physical size of the factories. During the period under observation (roughly five years), the corporation significantly increased the territory of production facilities and expanded capacities in terms of winding facilities. The number of working staff also increased to a significant degree due to external investments in the business.
- Business development during load-shedding period. The problem of energy supply has led to a considerable increase in the demand for solar systems – the business focus of Reliable Transformers.
In conclusion, taking into consideration the existing evidence, it should be concluded that Reliable Transformers have not sold their business after 2021 and are controlled by van Zyl family. Those who heard about their change of ownership should ask the source for the official confirmation.
What actually changed after 2021
For consumers, the verifiable changes after 2021 are of more interest than rumors of ownership, since they directly impact the issue of supply, quality, and volumes:
| Area | Before / earlier | Current (post-2021, as documented) |
|---|---|---|
| Public identity | Standalone “Reliable Transformers” | “A member of the Reltrans group of companies” |
| Factory | Benoni South facility launched 2019 (~4,000 m²) | Floor space more than doubled within the last five years; five overhead cranes to 16 tons |
| Winding capacity | Up to 3.5 MVA headline through the 2010s | Coil and foil winders rated to 6.5 MVA |
| Workforce | ~35 employees (mid-2023) | ~49 employees (mid-2026); steady YoY growth |
| Renewables base | First solar project 2016; 250 MW under contract by 2019 | More than 1,200 MW of inverter-duty transformers installed in South African renewables |
| Engineering tools | Proprietary CAD/design and production-planning software | AI-driven design software added to the in-house toolchain |
| Sector spread | Mining-led | Mining, industrial, renewables (solar/wind), agriculture, commercial, motor control, neutral earthing, alternative power |
None of these changes compromised the fundamentals for customers, which includes ISO 9001:2015 quality management, SANS and IEC manufacturing, SANAS-conducted testing, and the design flexibility since 1982.

If you are comparing its offering with other suppliers, two guides will help you evaluate the technical side. The acceptance-test expectations that should apply to any new unit — routine tests, impulse tests, and the reports you should receive with delivery — are covered in our 변압기 테스트 가이드.
The maintenance reality of an installed fleet is a separate subject: oil sampling, dissolved-gas analysis, and condition monitoring decide whether a transformer reaches its designed life or fails early, and that is the territory of our 변압기 오일 테스트 기초 article — reading it before you sign a service contract will tell you what “oil analysis” should actually include.
Where the company exports
Reliable Transformers operates in South Africa and in the larger SADC region, and has been able to manufacture equipment for clients in Zambia, Angola, Mozambique and the DRC amongst other areas, with supplies even reaching Burkina Faso in West Africa. The company’s transformers have made their way to Texas and Mexico via resellers. The company wants to be described as “the best” rather than “the biggest,” endorsing regional rather than global market activity, which is more appealing to those who prefer quick turnaround times and reactive design capabilities.
Strengths, and why ownership continuity matters to buyers
The strength of the company can be perfectly illustrated through the features of a model moderation company.
- Bespoke design speed: The company has its own software suite of design, document control, CNC control, and production planning. Therefore, it is possible to eliminate any prototyping and have full visibility to the order instantly.
- Testing integrity: The units of the company’s products undergo IEC and SANS tests in a testing bay equipped with all necessary devices as well as instruments maintained and calibrated by SANAS-accredited laboratories.
- Vertical control: The full CNC-cutting, plasma-cutting activity, bending, welding, purification of oil, and the process of fabrication of radiators are made in-house at a site of more than 4000 square meters.
- Agility: The time from design to manufacturing is short since each order is made individually.
The issue of ownership with regard to the acquisition of transformers is a serious one and should not be taken lightly. When a transformer is being bought from a private firm, it is an asset for 25-40 years. In this case, the ownership of the transformer will determine whether the buyer will continue to benefit from the 10-year warranty of the product and the service contract in the 8th year of use. If a family company with a generational succession (1997) remains a family business and is conducting active modernization of the production, it should be seen as a lower counterparty risk.
How to verify a private supplier like this one
If you have the Reliable Transformers or any other transformer manufacturers on your list, consider ownership confirmation to be one among multiple important due diligence actions:
- Look up in CIPC: In South Africa, as per the companies and intellectual property act, the registration of companies and their directors is publicly available to verify the supplier’s registration and the appointment of the directors.
- Get the B-BBEE certificate: The broad-based black economic empowerment is important in South Africa as it is needed in both the public and private sectors. The document confirms the shareholding structure as well.
- Confirm the ISO’s validity: ISO certificates usually have a lifetime of three years, therefore an updated copy of TUV Rheinland document or equivalent is always needed.
- Get the test report: Ask the supplier about routine tests performed on the transformers produced in their factory, if they are using SANAS calibrated instruments.
- Get into the factory: Inspecting the premises of Reliable Transformers is the easiest way to check if the manufacturer has a 4,000 m² production area, a 16-ton crane, and 6.5 MVA winding capability.

결론
When it comes to the question of how Reliable Transformers ownership has changed since 2021, there is an unequivocal answer: the South African company, originally established by H.J. van Zyl in 1982 and headed by his son Andre van Zyl since 1997, remains family-owned. There is no record of any new buyer or acquisition since 2021. What has changed, however, is size and structure — a public identity as a member of the Reltrans group of companies, an increase in the size of the factory by more than 100% over five years, winding capacity increased to 6.5 MVA, staff increased to around 50 people, and a renewable energy portfolio over 1,200 MW in terms of installed transformer capacity. Therefore, instead of cashing out, the second generation is aggressively investing. As for practical recommendations, nothing has changed regarding ownership: you need to check the CIPC registration and the current ISO certificate and ensure SANAS-compliant testing of each specific unit offered. If you do, you will be sure that the Reliable Transformers unit is going to function properly, whether the company is in its first or second generation of ownership.
