The Open Terminal Blocks are designed to align with the latest advancements in terminal block technology. The insulating base material is high-grade Polybutylene Terephthalate (PBT), a robust, non-hygroscopic material with excellent insulation resistance and high impulse voltage endurance. For 100A terminal blocks, high electrical-grade Phenol formaldehyde resin (Bakelite) is used, offering superior insulation resistance and impulse voltage handling capabilities.
The electrical conductors are crafted from premium copper alloys, combining copper and zinc in an optimal ratio to ensure minimal current transmission loss and controlled temperature rise within specified limits. Screws and washers are made from high-tensile mild steel, with options for customization to stainless steel 304 grade or brass. Mild steel screws undergo zinc passivation with a specific grade of zinc, providing exceptional corrosion resistance in harsh environments, while brass screws are coated with bright nickel for added durability and a polished finish.
