Cembre Copper Tube crimping lugs have a much high copper content than many of its competitors. The cross section of the lug has the same copper content as the conductors it's attached to, allowing the joint to carry the same current as the conductor without the risk of burning out. They are annealed (slowly cooled) which plays a vital role in avoiding cracking or breaks between the barrel and palm, particularly if the application subjects them to vibration. The lugs are electrolytically tin plated to avoid oxidation and the presence of an inspection hole facilitates full insertion of the conductor. Each lug is stamped with the manufacturer and lug size for confidence in fitting and traceability.
