Power Generation and New Energy

Copied to clipboard

Overview

High-current connectors (ranging from 10A to several thousand amps) and high-current distribution boxes serve as the core connection and power distribution hubs in power generation, new energy power generation, energy storage, and charging applications. They are designed to address four key challenges: high-power transmission, safety and reliability, efficient maintenance, and adaptability to extreme environments. These solutions cover the entire chain of photovoltaics, wind power, energy storage, new energy vehicles, and traditional power generation.
