Why Is The Conductive Tube Of The Cable Terminal Block Thickened?

The cable lugs conductive tube is responsible for the primary current transmission. When the wire lugs conductive tube is thicker, its cross-sectional area is larger, the current distribution is more uniform, and the metal resistance is reduced. Heat and resistance losses in the conductive path are also reduced.

If the electrical lugs conductive tube is not thick enough, it is prone to metal fatigue, deformation, or poor contact due to current concentration and localized heating during long-term use. Especially in high-current or vibration environments, a thin terminal lugs conductive tube may lead to unstable connections and increased contact resistance.

Appropriately increasing the thickness of the copper lugs conductive tube material helps maintain stable conductivity. This not only improves mechanical strength but also reduces the risk of failure due to thermal cycling, corrosion, or fatigue.
