RIR Power Secures Overseas Thyristor Order

28 May 2026 CW Team

RIR Power Electronics has secured a large overseas order to supply 120 units of its 5kV silicon-controlled rectifier (SCR) thyristors in the first phase. The order reinforces growing global confidence in the Mumbai-based company’s high-performance semiconductor devices, assemblies and energy management systems.

The company’s 125 mm 5kV SCR thyristors are high-current semiconductor switching devices designed for heavy-power applications requiring very high current handling, short-duration high di/dt pulses and strong reliability. Built with a 125 mm silicon chip in press-pack construction, the devices offer high mechanical reliability, optimised lifetime control, low thermal resistance and strong surge current capability.

The order has been placed by a leading Class I Electrical EPC contractor engaged in turnkey electrification projects for industries and power plants worldwide. RIR Power Electronics said the order is among the largest single orders for its 125 mm pulse power thyristor range and is scheduled for execution by the end of 2026.

N Ramesh Kumar, MD & CEO, RIR Power Electronics, said the company expects to expand such mandates and strengthen partnerships with Class I Electrical EPC contractors. He added that RIR Power Electronics is also setting up a state-of-the-art silicon carbide semiconductor manufacturing plant in Odisha to support India’s semiconductor manufacturing ambitions.

The company’s high-power press-pack thyristors are used in HVDC transmission valves, Static VAR Compensators, medium-voltage soft starters, high-power rectifiers, crowbar protection systems, pulsed capacitor discharge systems, traction and legacy locomotive systems, and defence applications requiring high-energy bursts in short durations. RIR Power Electronics expects stronger business momentum as it broadens its product portfolio and expands its global presence in the power semiconductor industry.

Railways To Operate Over 300 Special Trains For Rath Yatra

Union Railway Minister Ashwini Vaishnaw announced that Indian Railways (IR) will operate more than 300 special trains for the annual Jagannath Rath Yatra in Odisha and over 100 special trains during the Onam festival in Keralam. He flagged off the Nanded–Mumbai and Tanakpur–Nanded Express trains and inaugurated the extension of the Tanakpur–Pilibhit service up to Shahjahanpur via video conference from Rail Sadan in Bhubaneswar. He noted that the summer season, which concluded on 30 June, had seen a record 15,000 special trains. Vaishnaw stated that the newly launched services are intende..

Vande Bharat Express To Start From Tripura Soon

Tripura Chief Minister Manik Saha said the Vande Bharat Express will commence operations from Tripura in the coming days after he flagged off the Agartala–Karimganj MEMU service at Agartala Railway Station. He recalled the rail history of the state, noting that a metre-gauge service first arrived in 1964 and that broad gauge reached Agartala in 2008 following national projects and later upgrades under the Act East policy. The event was described as a milestone for regional connectivity and the MEMU was presented as the first electric passenger train to originate from Tripura.\n\nSaha said he..

MEMU Suspension Disrupts Commuters Between Vadodara And Dahod

The Vadodara–Dahod Mainline Electric Multiple Unit (MEMU) service has been temporarily suspended for 26 days after its rake was diverted to Odisha to manage the surge in passenger traffic during the annual Rath Yatra in Puri. Indian Railways redeployed several MEMU rakes from different zones to meet the additional travel demand for the festival scheduled from the seventh of July to the second of August. As a result, train numbers 69233 and 69234 operating between Vadodara and Dahod will remain cancelled for the duration. Railway authorities advised passengers to use alternative train service..
