Skipper ETS manufacture a complete range of high quality IEC Standard 11kV and 33kV voltage class pole and ground mounted distribution transformers.

Our standard ratings start at 50kVA and go up to 3150kVA, they are designed to comply with the
Nigerian Distribution Network Operators technical requirements.

The transformer technology is derived from a technology transfer partnership from a ‘world leading’’
transformer OEM with a significant presence in Africa, Europe and the Middle East. Our manufacturing
principles and processes exceed internationally recognised standards to ensure that only highly reliable
and resilient transformers are connected to critical distribution networks.

Transformer designs are proven with over 32 years experience of being installed and applied in harsh
conditions and environments I.E. extreme high temperatures and/or tropical climates. This makes our
product the product of choice for West African electrical utilities and oil & gas operators. Whether the
requirements is for breathing conservator or hermetically sealed type transformers we are able to
support your specification and application needs.

Offering high operational performance properties in terms of voltage ratio, losses, impedance temperature
rise and optimised transformer layout or footprint.
