CONDUCTOR PRETREATMENT
All kinds of copper conductors can be clamped without treatment. DO NOT solder tin stranded conductors. The solder yields and
fractures under high pressure. The result is increased contact resistance and excessive temperature rise. Additionally, corrosion has
been observed due to the fluxes. Notch fractures at the transition from the rigid tinned part to the flexible conductors are also possible.
Ferrules can be used as a protection when wiring stranded conductors. Copper ferrules prevent the current transfer from being
influenced by dissimilar metals and remove the risk of corrosion. Always use the correct tool to crimp the ferrule.
