In Singapore Mors Smitt refurbished ordered by Hyundai Rotem type C151 metro cars. The 20 years old trains were refurbished; all the panels were replace by new panels with new type relays.
Through the lack off basic train information it was a challenge to design the circuit diagrams of the panels. Mors Smitt has been several times on site to check and compare the existing diagrams with the new design.
To relieve the customer, a turnkey construction for delivery of the relay panels was choosen in 5 different configurations. This was succesfull due to good teamwork between Hyundai Rotem, SMRT and Mors Smitt.
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.
