Why Do Pluggable Terminal Blocks Heat Up? ULO GROUP Uses High-Conductivity Copper Pins
The current-carrying performance of pluggable terminal blocks is closely related to the conductivity of their pin contacts. ULO GROUP's pluggable terminal blocks use high-conductivity copper pins, with temperature-rise testing demonstrating their current-carrying and thermal performance to support reliable electrical connections in industrial equipment.
Material Selection Determines Current-Carrying Capacity
Conductive materials are an important factor affecting the current-carrying capacity of terminal blocks. The material comparison in the video indicates that pure copper has a conductivity of approximately 100% IACS, or 58 MS/m, while brass has a conductivity of approximately 15%–35% IACS, or 10–20 MS/m. Compared with standard brass, copper offers higher electrical conductivity.
High-Conductivity Copper Pins for Better Performance
To meet the current-carrying requirements of pluggable terminal blocks, ULO GROUP uses high-conductivity copper for its pin contacts. Compared with standard brass pins, copper pins offer higher electrical conductivity, providing a material basis for improved current-carrying performance.
Temperature-Rise Testing Demonstrates Product Performance
The video shows the product testing process using an SH9408 multifunction temperature-rise tester. It highlights the ULO GROUP pluggable terminal blocks' stronger current-carrying capability and lower temperature rise, providing a demonstration of their current-carrying performance.
From conductive material selection to temperature-rise testing, ULO GROUP focuses on key details in terminal connections. Through material selection and product design, the company works to improve current-carrying performance and provide reliable electrical connectivity for industrial applications.
Reliable electrical connections begin with the right conductive materials. ULO GROUP remains committed to material quality and connection performance, developing well-engineered products to meet industrial application requirements and deliver dependable connectivity solutions.
