Technical Advantages Of Using Aluminum Hydroxide In Copper Terminal Blocks

In the design of electrical connection systems for type copper terminal block, using aluminum hydroxide (Al(OH)₃) as a flame retardant offers significant advantages to the structure and performance of type copper distribution block. Aluminum hydroxide begins to decompose at approximately 200°C, releasing water vapor and absorbing heat, thus slowing down the rapid temperature rise.

Type copper terminal strip may experience localized heat concentration under high current density or short-circuit conditions. Incorporating aluminum hydroxide into the plastic casing or composite structural materials used for terminal blocks can trigger an endothermic reaction at the initial stage of heat source activation, thereby delaying the occurrence of thermal runaway.
