A demonstration of organizational culture promoting adaptability and reliability.
As of November 2021, we are excited to announce that we are a fully Covid-19 vaccinated company.
Vaccinations started rolling out in quarter one this year, and we saw this as an opportunity to not only promote a positive and safe community in the metal and engineering sector – but to ensure that our customers and suppliers can continuously rely on us to deliver work on time and of a high standard.
Covid-19 has taken a large toll on South Africa, causing delays within many sectors and limiting many small and big businesses alike. Unfortunately, we do not know what the future has in store for us, however, we do promise that we will take the actions necessary to mitigate the effects on internal and external stakeholders.
However, ensuring a strong work ethic is far from our only concern – we make it a priority to create a safe and comfortable work environment for all employees.
Top management took great leaps to ensure the health and well-being of the Armcoil workers in regards to the vaccination. CEO, Peter Flint explains, “We took into consideration peoples religious beliefs, as well as medical issues and assisted all workers individually to the best of Armcoil’s ability.” This includes arranged transport, time off from work, as well as sick leave where deemed necessary.
Finally, we would like to show appreciation to our customers and suppliers for continuing to do business with us during these uncertain times. We are all part of the same community, and we stand together to do whatever possible to put a stop to the negative effects Covid-19 is having on our country and other African countries.
With the fourth quarter coming to an end, we can say this has been a year of overcoming unavoidable obstacles, however, through consistent effort, we have high hopes for a healthier 2022.

ARMCOIL’S FIRST AFRICAN UTILITY WEEK 2015
It was that time of the year again where Cape Town was buzzing with the excitement for the African Utility week 2015. Exhibitors from all over the globe were getting ready for a week of networking and promoting of their brand products, services and company presentations.
ArmCoil New Machines Division personnel who attended the exhibition were:
Christopher Gomez (New Motors and Spares)
Elloeen Da Silva (ACEM locally manufactured transformers)
Janine De Villiers (Pearl Power Transformers)
Teren Gomez (ArmCoil Cape Town Representative)
Morne Bosch (General Manager-Sales & Marketing)
Peter Flint (Managing Director)
Pearl Electric Transformers China Sales and Marketing Team
The show ran from 12-15 May 2015, Armcoil’s main objective for this show was to promote our locally manufactured transformer brand, ACEM and our Power Transformer Brand Pearl Electric for which Armcoil is the sole agent for Sub-Sahara region. Our stand was visited by many municipalities, substation contractors, civil contractors and electrical engineers; this was our main target group for this show.
Morne Bosch also gave a Technical Presentation supported by our MD Peter Flint to approximately 30 young and upcoming engineers. The presentation is available on the ArmCoil website for downloading.
Our technical and marketing team from Pearl Electric were available for any questions regarding the Pearl Electric product as well as our Marketing Manager, and internal team were available for the ACEM Brand. We had a CRT (Cast Resin Transformer) on display manufactured by Pearl Electric which brought many visitors to the stand.
To conclude, we received numerous requests for quoatations on ACEM Transformers and our Site Services abilities by project houses and utilities who visited our stand.
ArmCoil was the buzz at the exhibition as we displaying our Cast Resin Transformer which drew many vistors to our stand.
We were very impressed (including our Managing Director) with the turn out, organisation and general good vibe of the AUW and we look forward to exhibiting at the next one in 2016!
ArmCoil is proud to announce that after months of dedicated hardwork we are now an ISO14001 accredited Manufacturer and Repair Company which also conducts On-site Services across RSA and Africa.
Achieving this internationally recognised standard is only the start of our pursuit to achieve the very highest standards for ArmCoil’s business practices.
ArmCoil will continue to implement these practices for the benefit of our employees, customers, suppliers and communities we operate in.
OUR NEXT GOAL SANS OHSAS 18001
Mission statement from MD (Mr Peter Flint)

ArmCoil recognizes that by integrating environmental, health and safety management practices into all aspects of our business, we can offer products and services while conserving and enhancing resources for future generations.
ArmCoil strives for continuous improvement in our environmental, health and safety management systems and in the environmental quality of our products, processes and services.
Power and distribution transformers are all basically the same design and vary only in the method of cooling them, oil or air. By far the vast majority of transformers have been oil cooled using mineral oil.
Recent environmental and fire hazard considerations however have resulted in greater numbers of air cooled transformers being manufactured without necessarily taking into consideration the alternatives or implications of the decision. Below is a summary of the various alternatives.
Mineral oil filled transformers.
This is the traditional distribution transformer as has been in operation for many years.
- Lowest cost
- Largest installed base of units for interchangeability
- Good ability to withstand overload
- Operates at relatively low temperature (max 105â°C but normally 60-80â°C)
- Physically compact
- Robust construction
- Fully enclosed
- Components including oil readily available
- Prone to leakage
- Mineral oil is an environmental hazard in the event of spillage
- Mineral oil has a low flash point in the event of fire
- PCB levels need to be controlled.
Dry type or Air cooled transformers
There are two main methods of manufacture of dry type transformers, namely Vacuum Pressure Inpregnated insulated windings or Cast Resin windings.
- No fluid which can become an environmental or fire hazard
- Cast Resin windings are fully encapsulated preventing the ingress of foreign particles
- Higher cost. An oil cooled transformer will operate at around 3 â€“ 3.5 A/mm2whereas a dry type transformer will operate at around 1.5 â€“ 2 A/mm2 . There is thus approx double the amount of copper in a dry type transformer when compared to an oil cooled one.
- The no-load losses in a dry type transformer are normally higher than those on a similar sized oil cooled transformer
- The efficiency of air as a cooling medium is far less than that of oil. As a result air cooled transformers normally have an IP23 enclosure rating, although IP55 is possible but the enclosure is massive in order to accommodate the cooling required.
- The operating temperature of dry type transformers is normally in excess of 120â°C. Although the windings and insulation are rated for this temperature other objects which may come to rest or be placed on the transformer are normally not rated for such high temperatures. This presents a fire hazard.
- The ability to withstand overload is significantly lower than oil cooled transformers.
Seed or silicon oil filled transformers
These are standard oil cooled transformers which are filled with either a seed or silicon oil. Silicon oil has the advantage of higher temperature ratings but has the same environmental disadvantages as mineral oil and is therefore not normally considered an option.
Seed oil which can be manufactured from various different seeds or vegetables not only has a significantly higher temperature rating but is fully bio-degradable.
- Environmentally acceptable.
- High temperature rating
- Existing mineral oil cooled transformers can be converted to seed oil
- Will still operate at the same relatively low temperature as mineral oil cooled transformers.
- Good ability to withstand overload.
- Physically compact
- Robust construction
- Fully enclosed
- Lower cost than dry type transformers
- Higher cost than mineral oil cooled transformers
- Leakage will remain a problem, though the oil leaked is bio-degradable.
- The oil is not as readily available as mineral oil
- There is a risk of theft of the oil.
Attached please find some literature on seed oil which details the advantages.
The costs of the various alternatives will vary depending on the specific enquiry however a rough rule of thumb would be as follows, assuming a standard mineral oil cooled transformer as being 100
Mineral oil cooled transformer 100
Dry type transformer (IP23) 160
Dry type transformer (IP55) 200
Seed oil cooled transformer 130
Where environmental and fire hazards are a major consideration then seed oil cooled transformers are a viable economic alternative.
