DIS-TRAN Steel, LLC supplies substation structures using any combination of standard steel shapes or tapered tubular sections. They are fabricated by using customer supplied shop drawings or can be designed and detailed with our in-house engineering and structural detailing team from customer loading information. Stop by our Booth 1253 for more information on how we can help you with your substation steel project needs. We look forward to seeing you.
Two most common dead-end structures in a substation are A-Frames and H-Frames.
A-Frame •Arranged to handle higher tensions but has larger foot print •Always have at least four legs and one conductor beam •Facilitate long line spans or high loading requirements •Maximized when conductors come straight in with minimal line angle •Higher moment loads at the base are transformed into tension/compression loads, resulting in smaller foundations
H-Frame •Arranged to handle mid-range to slack span tension with a smaller footprint •Always have at least two legs and one conductor beam •Generally high moment loads at the base resulting in larger foundations •Spacing between legs is determined by the electrical requirements •Effective to use in smaller or compact substations when smaller footprint is needed
The majority of transmission structures are mono poles/single standing poles. The three phases and static wire are stacked vertically on the poles. The static wire is located at the top to protect the lines from lightning.
Common transmission structure types:
Dead-End Pole •Wires come in at an angle •Typically the mid-size poles of the t-line •Supports line as it travels through the right-of-way to remain within boundaries •Supports conductors above ground Tangent Pole
