Braced line posts have enabled compact transmission lines in the voltage range of 115 kV to 230 kV. Now line compaction is being considered at progressively higher voltages (EHV range) to develop structures with better visual amenities, smaller foot print, narrow right-of-way requirements and the economic benefits of lighter construction.

However, at 345 kV and above voltages as the section lengths increase due to electrical requirements, the mechanical capabilities of standard braced line posts with typical components becomes a limitation. The low working performance restricts span lengths and increase overall project cost and construction efforts.

The simplest insulator system for compact transmission line construction is a composite horizontal line post. However, line post insulators are limited in their vertical loading capabilities and thus cannot support longer spans or heavier conductor systems. Composite braced line posts are designed for applications similar to a line post but with an added suspension 'brace' insulator to significantly increase the vertical load capacity of the assembly.

Should a transformer’s cooling system fail unexpectedly, you might find yourself looking for a quick-swap, temporary solution to bring your transformer back online and restore power to your customers.

Trantech Radiator Products’ latest addition to cooling solutions is the Mobile Auxiliary Cooler (MAC). Offering a range from 40 to 215kW of cooling capacity per unit with 3-stage capability (ONAN, ONAF and OFAF).
