Tokyo, 2025 – GBP K.K. announces the continuation of orders for distribution transformers compliant with Japan’s Top Runner Second Judgment Criteria (legacy 2014 standard). While many manufacturers have already stopped taking orders for these models, we remain committed to supporting customers who still require them for retrofit, repair, or like-for-like replacement projects.

Our transformers maintain the same specifications, dimensions, and performance as major manufacturers, and we can offer an indicative lead time as short as two months for standard configurations (conditions apply). This ensures that your projects can move forward with minimal disruption.

GBP K.K.’s Comprehensive Solutions

1.Precision in Replacement
Transformers are engineered to match the mounting dimensions and terminal positions of widely used legacy models, minimizing the need for panel modifications or additional construction work.

2.Accelerated Delivery
Through integrated management of design, testing, and shipment, GBP K.K. is able to offer an indicative lead time of two months for standard builds, assisting customers in recovering delayed project schedules.

3.Cost Efficiency
By leveraging standardized design and scale-based procurement, GBP K.K. ensures competitive cost performance without compromising quality or reliability.

4.Technical Expertise and Support
GBP K.K.’s Japan-based engineering and technical teams provide comprehensive support, from site inspection and design to installation and re-energization. Documentation—including drawings, specifications, and test certificates—is prepared in client-specific formats to streamline internal approval processes.
