We are  a major supplier of power and distribution transformers; both new and refurbished, mining substations, kiosks, medium and high-voltage switchgears.

Transformers to meet MEPS efficiency standards

The availability of new transformers, which can be manufactured to minimum energy performance standards (MEPS), has enabled HAFE to offer environmentally-friendly units. MEPS efficiency units provide a 70% reduction in loss when compared with standard efficiency transformers. This in turn means that power stations are not working as hard and consequently producing fewer emissions that damage the environment.

Oil-filled transformers that meet environmental standards

HAFE has forged good working relationships with suppliers of new transformers. HAFE products are generally available from 50kVA 3.3kV up to 370MVA and 500kV are compliant with IEC76-2/AS60076/2374 standards.

Distribution transformers include features, such as:

• Copper foil
• High-voltage winding
• Vacuum drying and filling.
• MEPS efficiency standards

HAFE has sourced power transformer manufactures in China. These factories offer high-quality units to international standards and have ISO 14001 and ISO 9001 accreditation. The range HAFE offers for power transformers is from 66kV to 500kV and 5,000kVA to 370,000kVA.

Power transformers include features, such as:

• High-efficiencies, which reduce network loss and costs.
• High short circuit and insulating strengths
• Low temperature rise
• Low noise
• Reliability in operation

In today's world, where the need to meet environmental, safety and financial considerations have become paramount, HAFE offers the Envirotemp FR3 fluid from Cooper Power Systems. This fluid, which is a direct replacement for transformer mineral oil, meets all of the above standards. It can be supplied with new transformers or retro filled.

Using Envirotemp FR3 fluid provides improvements in safety, environmental responsibility, performance and savings.

Dry-type transformers

The HAFE supplies high quality cast resin transformers from China. HAFE represents some of Asia's and the world's biggest suppliers, with a range of up to 20,000KVA at 35kV.

These low-loss transformers are manufactured using materials sourced from the world's best. The cast resin system is by CIBA Geigy. The low-loss, low-expansion silicon steel is made by Nippon Steel and its windings in class F insulation are all copper, including an LV strip from KM Germany.

ISO 9001 quality accreditation by BSI, coupled with short circuit type tests and thermal shock test certification from Kema High Power Laboratory, are all testimony of transformer reliability and efficiency in applications for high-rise and public access buildings, the oil and gas industry, hotels and underground power.

Bunded kiosks to prevent oil damage and endure cyclones

HAFE has designed and developed bunded kiosks. Being completely enclosed, any oil spills remain contained within the bunded area preventing oil damage to the surrounding site. No onsite foundations are required and HAFE offers a flexible design to accommodate client specifications. Recognising the need to construct for cyclone conditions, HAFE continued development of the kiosk designs and now produces cyclone-rated units to Category D, Terrain 2, 88m a second. These kiosk designs continue to develop as new technologies become available.
