Klemko SUPER PIDG insulated cable lugs are easy to process and perform extremely well on the mechanical strength of the connection. This has an average pull-out force > 60% of the breaking force of the original vein. Of course, a professional crimping tool must be used (see crimping tools). The electrical conductivity of these cable shoes is also of a top level due to an optimal alloy of brass with a tin-plated surface.
