GRL Shines at 2025 Low-Voltage Electrical Industry Conference

2025-06-27

GRL attended the 9th General Low-Voltage Electrical Industry Conference on June 24–26, 2025, in Hangzhou, China, bringing our latest electrical protection solutions and renewable energy components to over 460 industry delegates from 210 member companies.

Under China’s carbon neutrality and “Dual-Carbon” targets, the low-voltage sector is embracing smart grid technology, high-current switchgear, and new energy electrical protection. GRL’s General Manager, David Liu, joined peers in shaping industry standards and roadmaps.

GRL’s “New Energy Protection & Connection Solutions”

“Wind, solar, and energy storage demand high-voltage, high-current, high-capacity components,” noted GRL Product Manager Chen. “Our challenge is to deliver safe, reliable photovoltaic protection devices, energy storage safety solutions, and charging station components that meet these evolving requirements.”

In a featured presentation—“GRL’s New Energy Electrical Protection and Connection Solutions”—our senior experts highlighted:

1、Wind Power Trends:

Floating Offshore Wind: Corrosion-resistant composite insulators and high-purity copper busbar connectors for marine environments.
Turbine Grid Integration: Smart surge protective devices and high-speed current-limiting fuses to handle lightning and grid disturbances.

2、Photovoltaics & BESS :

High-Voltage PV Systems: Introduction of 1500 VDC PV fuse links (DNPV1085/1065) paired with GRL’s DNH50 PV isolator switches for string-level safety.
Energy Storage Safety: Modular ESS fuses (up to 3000 A, DC1500 V) alongside our DNRH8 combined switch for compact, all-in-one BESS rack protection.

3、Digitalization & Lean Manufacturing:

Smart Monitoring Modules: Undervoltage trip and JDQMK relay modules provide real-time feedback and remote control via SCADA/BMS integration.
Lean Digital Factory: Over 30 automated production lines and digital performance dashboards ensure consistent quality and rapid order fulfillment

Popular Science Explainer:

1、What Is a Current-Limiting Fuse?

It rapidly “chokes” a short circuit, limiting peak currents to protect sensitive components, such as inverters and transformers.

2、How Does a Combined Switch Work?

By integrating pre-charge, main switching, and undervoltage trip in one unit, it simplifies wiring and prevents inrush damage in battery and solar systems.

3、Why IP67 Matters？

An IP67 rating means the device is fully dust-tight and can withstand immersion in water up to 1 m for 30 minutes—critical for outdoor solar and marine applications.
