Our Padmount Transformer Support Culvert, also known as a uniculvert, padmount culvert or transformer culvert, is engineered to provide reliable, durable below-ground support for pad-mounted transformers in electrical distribution systems. Cast from reinforced concrete, it sits beneath the transformer cabinet, supporting its weight while allowing cables to feed cleanly from the ground up into the cabinet.
Bundaberg Concrete Casters proudly supplies Ergon Energy and the Department of Transport and Main Roads, and delivers throughout Queensland.

Frequently Asked Questions
What is a uniculvert?
A uniculvert is a precast concrete culvert installed below ground to support a padmount transformer cabinet and guide cables up into it. Uniculvert is the term used in the Energy Queensland approved-supplier catalogue. The same product is also called a padmount culvert, a padmount transformer support culvert, or a transformer culvert.
Is a padmount culvert the same as a uniculvert?
Yes, they are two names for the same product. The base the culvert sits on is sometimes called a biscuit. Bundaberg Concrete Casters manufactures both the culvert and the base at its Bundaberg yard and delivers throughout Queensland.
