I. Grand Exhibition: Focusing on the Frontier, Participating in the Industry's Grand Gathering The 32nd China International Power Equipment and Technology Exhibition (EP China 2025) came to a successful conclusion on November 20th. As a highly influential power industry event in the Asia-Pacific region, this exhibition gathered the world's top technologies and innovative achievements. Jiayi Electric Co., Ltd., a high-tech enterprise and undertaker of the National Torch Plan Industrialization Demonstration Project, participated deeply in the exhibition. With the theme of "Smart Power Distribution, Safe Future", it showcased its full range of intelligent miniature circuit breakers and new-generation intelligent residual current devices (RCDs) as core products. It set up a professional and interactive exhibition space at the exhibition site, attracting a large number of industry professionals to stop and exchange ideas, making it one of the highlights on site.

II. Product Core: The full matrix of intelligent products made a sensational debut, precisely matching diverse scenarios. At this exhibition, Jiayi Electric systematically showcased its technological achievements from years of deep exploration in the field of intelligent power distribution. The product line is clear and covers a wide range, forming a powerful solution matrix.

1. Safety Guardian Pioneer: The new generation of intelligent small residual current devices (RCDs) stands as the star product of this exhibition. Jiayi Electric's new generation of intelligent small RCDs integrates safety, intelligence, and reliability, marking the company's technological breakthrough in the field of intelligent power distribution. The research and development of this product spanned a year, embodying the hard work and wisdom of Jiayi Electric's R&D team, and reflecting the company's determination to persist in technological innovation and overcome industry challenges.

Overcoming Challenges: In a Compact 12-Month R&D Cycle, the Jiayi Electric R&D Team Tackled Technical Difficulties Faced by Traditional Leakage Protectors, Which Are Passive in Response and Reliant on Manual Operation. To Implement the Core Function of "Intelligent Continuous Power Self-Inspection", the R&D Staff Conducted Hundreds of Circuit Design Optimizations and Thousands of Hours of Stability Testing, Overcoming Technical Challenges Such as Current Surge Protection and Bypass Switching Reliability During the Self-Inspection Process. The Technical Team Often Worked Late into the Night Just to Find a Better Solution. It Was This Spirit of Craftsmanship, Striving for Excellence, That Ultimately Achieved Reliable Self-Inspection While Ensuring Continuous Power Supply.

This product has achieved a revolutionary leap from traditional "passive response" to "active early warning": intelligent regular self-inspection: through innovative bypass unit design, the device can automatically complete monthly functional tests without any power interruption, completely eliminating the safety hazards caused by human forgetfulness leading to protection failure. It is particularly suitable for homes, data centers, and other places with high requirements for power supply continuity.

Real-time temperature monitoring: Equipped with a precise built-in temperature sensor, it continuously monitors the temperature of the terminal blocks, promptly detecting overheating risks caused by faulty connections or aging. Through local or remote alerts, electrical fires can be prevented before they occur.

Highly integrated design: A single device integrates leakage protection, automatic reset over-voltage and under-voltage protection, electric energy metering, and remote control, achieving a "four-in-one" function. This not only enhances system reliability but also significantly reduces installation costs and space occupation.

2. Smart Electric Energy Meter External Circuit Breaker Series: Basic Fee Control Type: Offers a variety of pole options from 1P+N to 4P, with rated currents ranging from 32A to 125A. It features remote control of on/off switching, making it a stable and reliable choice for upgrading traditional fee control systems and implementing intelligent modifications.

Bluetooth communication type: On the basis of basic functions, it integrates a Bluetooth communication interface and supports the DL/T698.45 protocol, providing great convenience for on-site debugging, data reading, and near-field operation and maintenance. It is suitable for scenarios that require flexible access and mobile operations.

3. Professional Photovoltaic Grid-Connected Solution Series: In response to the special needs of photovoltaic power generation systems, we have launched cost-controlled, Bluetooth, and RS485 types of photovoltaic dedicated micro-breakers. All products in the series feature overload, short circuit, and over/under-voltage protection functions, effectively ensuring the grid-connected safety of photovoltaic systems. Multiple communication methods (AC220V signal, Bluetooth, RS485) are provided to meet the data acquisition and control needs of different levels of monitoring platforms. The rated current ranges from 63A to 125A, suitable for various household and commercial photovoltaic projects.

4. Small residual current device (with terminal temperature detection): Based on conventional residual current protection, it adds a crucial terminal over-temperature protection function, providing an additional "smart defense line" for the safety of the electrical end.

III. On-site Interaction: In-depth Exchanges and Wide Recognition During the exhibition, the Jiayi Electric booth was always bustling with visitors and lively interactions. The technical expert team focused on demonstrating the self-checking process, temperature alarm mechanism, and convenience of multi-protocol communication of the new generation of intelligent leakage protectors, allowing visitors to intuitively experience the safety and convenience improvements brought by technological innovation. Many power grid companies, design institutes, system integrators, and end users highly praised Jiayi Electric's products for their high integration, proactive safety concept, and flexible networking capabilities, and conducted in-depth negotiations on specific project cooperation.

IV. Value resonance: Addressing core industry pain points with innovative technology. Jiayi Electric's product matrix precisely responds to the core demands of the current distribution field, which is moving towards intelligence, high safety, and high reliability. From addressing the pain point of "monthly manual maintenance" due to leakage protection, to preventing fire hazards caused by overheating of wiring terminals; from meeting the management needs of grid-connected distributed energy, to achieving comprehensive monitoring and remote control of electrical parameters, Jiayi Electric is driving a profound transformation of the distribution system from "passive response" to "active early warning and intelligent management" through solid product innovation.

V. Looking Ahead: Continuous Innovation, Building a New Ecosystem of Smart Energy As a premium supplier to the State Grid and China Southern Power Grid, as well as an industry technology benchmark, Jiayi Electric fully demonstrated its determination and strength in driving development through innovation at this exhibition. In the future, the company will continue to rely on the research and development platform of high-tech enterprises, deepen the integration of IoT, sensing technology, and electrical protection, expand a richer intelligent power distribution ecosystem, and strive to become a trusted smart electrical solution partner for global customers. It aims to collaborate with the industry to empower the construction of a new power system and embrace a safer, more efficient, and greener energy future.
