2023年6月26日 · Overhead Equipment (OHE) refers to the infrastructure and equipment used in railway systems for the electrification and power supply of trains. OHE is typically installed above the tracks and provides the necessary electrical power to propel and operate electric trains.

Portal structures are used to accommodate OHE of many lines (2 to 8 tracks) where it is not possible to erect independent mast due to restriction of track center. There are three types of portal namely N, O and R type.

Where it's used in OHE. Specifications of TTB and TTU and its measurements.

OHE STRUCUTRES Different types of structures used to support OHE are: - 1. Broad Flanged Beam (BFB) mast 2. Rolled Steel Joist (RSJ) mast 3. Fabricated mast (K-series, B-series etc.) 4. Two/Three Track Cantilever (TTC) 5. Portal (N, O, R, P, G and BFB 6X12) OHE conductors are suspended from swiveling cantilever assembly generally
