Secure Conductor Material Transition From Aluminium To Copper

PFISTERER Sicon offer a range of mechanical shearbolt cable connectors with stepless shear-off bolts providing the right connector for any termination application for medium voltage power cables up to 66/72kV.

For years now, bolted clamps, connectors and cable lugs have been gaining ground as bolted connectors offer technical and practical advantages that conventional cable crimping and compression technology such as copper tube lugs cannot match.

With the Sicon CopperTop range of electrical connectors PFISTERER connects both the well-known SICON technology and the material transition from aluminium to copper in one cable lug. At the same time the copper/aluminium material transition is shifted to an area that easily can be covered with a heat shrink tube and can be secured against environmental impacts.

SICON CopperTop

This allows for example a safe and corrosion resistant connection to copper bus bars, especially in outdoor use. Additionally, the SICON CopperTop 332 907 082 is an alternative for connections in elbow connectors from aluminium cable to copper connection elements.

SICON technology

Like all other SICON connectors the CopperTop can be used independently of the conductor material and type*. The special aluminium alloy allows a safe and corrosion resistant connection of both aluminium and copper material with perfect electrical characteristics.

Thanks to the patented SICON step-less shear off bolts, optimal contact force is always achieved and avoids mounting failures.
