SEPTA - Electrical distribution board
Electrical distribution boards
For the Hyundai Rotem SEPTA project Mors Smitt designed the complete electrical distribution board fitted in a small space envelope. Especially for this train situation, with key points like low maintenance, plug and play connection and two sides reachable, a special design was made. Hyundai Rotem provided the train schematics and Mors Smitt designed the complete system and the mechanical design for the electrical distribution board.
Mors Smitt designed 4 separate panels which were mounted together in a square box. All connections are separate on a terminal panel on the square box and easy to reach. Two of the panels act as doors to give access to the other (inner) panels. The board is made according to the SEPTA required standards. Every wire has a ferrule and sleeve with a destination code and wire number.
Hyundai Rotem and Mors Smitt selected a configuration with MCB’s, D-U relays and contactors in one square electrical distribution board. Where possible Mors Smitt used cage clamp connections for fast mounting and low maintenance. For connection of the train wiring to the electrical distribution board X-com connections were used. (fast, easy mounting and low cost).
Mors Smitt assisted Hyundai Rotem with commissioning on site. All electrical distribution boards were fully tested (100%) before shipping to SEPTA. The delivery was according a
pre delivery schedule from Hyundai Rotem USA.
