Slaters Electricals offers a comprehensive range of power transformers, with both newly manufactured and refurbished equipment available.
Refurbished Power Transformers – for Purchase or Hire
Refurbished transformers have been at the core of the Slaters Electricals business for almost 100 years.
We hold quality used power transformers up to 132kV and 80MVA in stock and refurbish them in-house to ‘as new‘ condition. We supply and install used power transformers in a fraction of the long lead-times often associated with newly manufactured equipment.
Our refurbished power transformer range is ideal for large industrial users of energy and electricity generators who value our flexibility and short lead times to meet a temporary or unexpected increase in demand, cover for a breakdown or delivery delay, or those looking for a more cost-effective option.
