CADWELD放热放接 艾力高在1938年开发了CADWELD放热焊接工艺，现在CADWELD焊接作为最终的电力连接已经被业界广泛地接受。 可靠性 由于分子焊接能消除表面接触，电解质等不会渗透到导体交界面上从面导致氧化和并随时间老化 能承受大电流冲击
由于CADWELD材料的熔化温度要高于铜的熔点（1082℃）。所以，在由于大的故障电流导致的非常温升时，导体本身会先比接头处先熔化。 导电率 由于CADWELD放热焊接是真正的分子焊接，导体不会被破坏并且没有接触面，导体交界面的整体有效性没有改变。 For through
cable connections to the side of ground rods, there has never been a faster or
easier way to make a reliable CADWELD® connection. The two-piece GY mold lets
you make connections in a trench in about half the time it would take with
compression connections or other exothermic connections and at a fraction of the
cost. GY molds are simple to use and provide for easy cable alignment. The
molds include a baffle mold cover that reduces emissions and extends handle
clamp life. Features Ergonomic two-piece molds use standard L160 and L159
handle clamps - the same clamps you use with other CADWELD® molds Saves labor
costs. A GY connection can be made by one person in about one minute - much
faster than other methods Simple to use Easy cable alignment Includes a new
baffle mold cover which reduces emissions and extends the handle clamp life
