Tatung to Unveil 'T-NEX' 2026 Top-runner Compliant High-Efficiency Transformers at JECA FAIR 2026

Leading East Asia's Low-Carbon Power Transition

Tatung Co. (Taiwan Stock Code: 2371) is proud to announce its participation in 'JECA FAIR 2026 (74th Electrical Construction Exhibition),' held from May 27 to May 29, 2026. Under the core theme of 'High Efficiency x Decarbonization x Integrated Power Equipment,' Tatung will showcase a wide array of energy-efficient solutions, including transformers, IE4 ultra-high efficiency motors, and advanced inverters.

A dedicated new product launch event will take place on May 27 at 14:00 at the Tatung booth (Stand 3-44). The highlight of the event will be the official introduction of the '2026 Top-runner T-NEX Series' high-efficiency mold transformers, which are fully compliant with Japan's upcoming energy efficiency regulations. This launch marks a significant milestone in Tatung's commitment to power technology innovation and sustainable energy transition.

### 1. Development Background and Efficiency Gains of the T-NEX Series

As global industries move toward net-zero emissions, Tatung is deepening its R&D in high-efficiency products to help cities and industries achieve the dual goals of energy saving and stable power supply.

- **Full Compliance with Japanese Regulations**: With the full implementation of Japan's '2026 Top-runner' energy-saving system, efficiency standards for transformers have been raised by approximately 11.4% to 15% compared to 2014 levels. The 'T-NEX Series' has been specifically engineered to meet these rigorous JIS standards, satisfying demands for high efficiency, low loss, and low carbon emissions. - **Unmatched Cost Savings and Environmental Impact**: Taking a three-phase 500kVA mold transformer as an example, the T-NEX series can reduce energy loss by up to 54% compared to legacy models. This translates to an annual electricity cost reduction from approximately 614,000 yen to just 280,000 yen. Furthermore, it helps prevent roughly 6 tons of CO2 emissions annually per unit. - **Targeting a Massive Replacement Market**: There are currently over 2 million aging transformers in Japan nearing the end of their lifecycle. The T-NEX series is designed to address this vast replacement demand, serving as a critical solution for companies aiming to meet ESG and carbon-neutral goals through infrastructure upgrades. - **Disaster Safety and Reliability**: Featuring a cast-mold insulation design, the series offers superior safety and fire resistance. It is ideal for critical environments such as hospitals, commercial complexes, transportation hubs, and advanced manufacturing plants.

### 2. Product Launch and Exhibits

- **Launch Event**: Starting at 14:00 on May 27, technical experts will demonstrate the physical units and explain the technological breakthroughs and economic benefits of high-efficiency equipment. - **IE4 Ultra-High Efficiency Motors**: Also on display will be IEC-compliant motors with efficiency ratings exceeding 96%. These motors offer low noise and low temperature rise, suitable for various industrial applications including fans, pumps, and conveyors.

Tatung remains committed to expanding its footprint in the East Asian market and advancing the transition to a net-zero energy era alongside its global partners.
