Baker zunanji končni pokrov za visoko napetostno varovalko z nizkim tokom

Copper Outer End Cap for High Voltage Low Current EV Fuse is a component used in electrical fuses designed for high voltage and low current applications in electric vehicles. The outer end cap is made of copper and serves as a terminal for the fuse, allowing it to be connected to the electrical circuit. Its design is optimized for high reliability and performance in the demanding conditions of Evs .

The T2Y2 Copper End Cap for Fuse exhibits good electrical and thermal conductivity, corrosion resistance, and excellent processing performance. It can be easily welded and brazed. The copper element content in T2Y2 is 99.95%, and the phosphorus content is only 0.02%. Meanwhile, T2 Copper End Cap is pure copper, which is named after its purple color. It contains minimal impurities that could otherwise reduce electrical and thermal conductivity. Though a small amount of oxygen does not affect its properties much, it is prone to "hydrogen disease." Copper End Cap is unsuitable for processing in a reducing atmosphere at high temperatures (>370 stopinj), kot so žarjenje in varjenje ter poznejša uporaba .

Na učinkovitost varjenja bakrenih delov, vključno s končnim pokrovčkom varovalke in stikom, vpliva več dejavnikov . Prvič, visoka toplotna prevodnost zahteva visoki vir toplote in predgrevanje varjenja pred varjenjem. Additionally, copper has a large coefficient of linear expansion, leading to significant thermal expansion and cold contraction during the welding process, resulting in significant deformation. Copper's susceptibility to oxidation leads to the formation of cuprous oxide, which reduces plasticity and causes cracks during crystallization. Lastly, the solubility of hydrogen in liquid Baker ustvarja luknje za vodik med varjenjem, medtem ko kuprozni oksid pri visokih temperaturah, ki reagirajo z vodikom in ogljikovim monoksidom, povzroči nastanek por, če ni ustrezno pobegni
