Heavy Power Connector

We specialize in precision mold manufacturing and injection molding. This heavy power connector is designed for mining machinery and industrial energy storage systems, where extremely high current capacity and long-term reliability are required.

The housing is produced using one-piece injection molding with high-temperature, high-strength engineering plastic. It has passed strict voltage and flame resistance tests. It is suitable for environments with long-term exposure to oil, dust, and heavy industrial conditions. We perform 100% inspection on all products to ensure consistent quality.

We use a one-piece injection-molded silver-plated terminal design. Each pin supports up to 300A of continuous current. The silver plating ensures very low resistance and minimal voltage drop, enabling stable and efficient high-power transmission.

This heavy power connector is suitable for large-scale industrial equipment such as excavators and energy storage battery systems. With over 10 years of experience, we understand the requirements of high-power applications and ensure reliable performance.

We use an injection-molded silicone rubber sealing ring combined with a twist-lock mechanism to achieve IP67 protection. The connector remains secure even under long-term high-frequency vibration, preventing loosening or disconnection.

It is suitable for direct outdoor use without additional protective covers. We also support custom mold development based on core count and housing size. Many clients ask about 300A high-current applications-we provide stable and reliable solutions for such demanding requirements.
