All terminals are annealed, to avoid cracking and splitting when crimped and electrotin plated to combine maximum electrical conductivity with mechanial strength. An inspection hole is provided to check cable location prior to crimping.
Compression Terminal (Bimetal type)
Manufactured from a friction welded joint between high conductivity copper and aluminium to provide the ideal means of interconecting copper and aluminium conductors whilst avoiding bimetallic corrosion.
These washers have two sides, aluminum and copper, to protect from galvanic corrosion between copper alloy clamps and steel structures.
