Ferrules and Heat-Shrink Tubes

The ferrule , either smooth or threaded, minimizes the electrical resistance of the connection, dampens the mechanical force and prevents cable breakage. Also, the heat shrink tube prevents moisture penetration and relieves mechanical stress.

The ferrules and the shrink tubes mechanically reinforce the bypass connection and help avoid a hot spot, protect the cable and extend its life.
