Welcome to TSL, Transformer Specialties Ltd On-line Web site.
Thank you for choosing to browse New Zealand's leading Transformer Manufacturer web-site, the following is a little information about our company or you may wish to contact us.

Transformer Specialties Ltd was established in Auckland, New Zealand in 1985. The transformer industry before then lacked a manufacturer that was able to manufacture a transformer urgently, usually within 24 hours, we soon filled this niche market and haven't turned back. Constant investment in quality staff, product development and manufacturing technology has placed TSL as a leading transformer manufacturer both in New Zealand and overseas.

All our transformers are manufactured in New Zealand to ASNZS61558, (ASNZS 3108) and other international standards.
