HV Cable Joints & Terminations

The Pfisterer SICON is the first cable connector system with stepless shear bolts. The patented stepless Sicon shear bolt allows the joint to be used with a wide range of cross-sections. Pfisterer bolted connections offer technical and practical advantages that compression connections cannot provide. The specially designed step-less SICON shear bolt feature enables the inline connector to exert the maximum clamping force onto conductor to be achieved, making the SICON screw connectors superior to other mechanical connectors on the market. Pfisterer Sicon Mechanical Shear Bolt Lugs are used to terminate high voltage cable conductors, stranded copper or solid aluminium, prior to installing heat shrink or cold shrink cable terminations.

Other features of the Pfisterer Sicon High Voltage Mechanical Lugs include:

•Smooth breakage of the shear bolt simplifies the tightening process.
•Shear bolt breaks off flush with the connector body, no need for port-hole filling.
•Superior compressive force, even suitable for Class 5 fine-stranded conductors.
•Internally grooved to aid electrical connection and protect against conductor oxidisation.
•Blocked design to provide an oil or water barrier.
•Shears at Torque level of 52Nm (+/-7Nm).
 

Installation of High Voltage Mechanical Shearbolt Cable Lugs requires stripping the high voltage cable insulation for the distance specified in the cable jointing procedure. With HV copper cable conductors, it may be necessary to wrap them with brass gauze.
With HV solid shaped aluminium conductors, it may be necessary to straighten or twist the core using special cable core twisting tools before inserting them into the connector. Wen tightening/shearing the bolts the HV connector can be held with an insulated holding tool. To prevent the High Voltage cable core from bending and damage to the insulation whilst shearing the bolts, always hold the body of the connector with a grip device before shearing the bolts. On completion of the connector installation, recover all the sheared off bolt heads and count them to check that the number of heads recovered is the same as the number of bolts fitted. This ensures that the cable jointer has not trapped bolt heads, for example inside the insulation tubes. Check that all bolts have sheared correctly, at or just below the surface of the connector.
