Factory Cheap Hot Shear Head Bolt Connector - SICON – the first stepless shear bolt. – Waxun Detail:
The design strength of the multi-stage shear bolt – the integral predetermined breaking points – is at the same time its decisive weakness. Each breaking point forms a discontinuity in the load- bearing thread, and the maximum clamping force can- not be achieved. A further disadvantage: The stages must be very accurately matched to the conductor of the cable- used – otherwise the bolt will break at the wrong position. New from PFISTERER: Stepless shear bolts. Special design feature: No predetermined breaking points in the thread. This ensures the optimum thread load for any range of cross-sections. The bolt always breaks even with the surface of the clamp body – nothing protrudes, and nothing has to be filed to make the sleeve fit.
Advantages
Up to 30 % increased contact force compared with conventional type terminals
Bolt base plate for uniform friction and increased contact force
Nothing protrudes, no need for filing
Full utilisation of the thread loading for any size of conductor
No special tool needed
Smooth breakage of the shear bolt simplifies tightening process
The remains of the bolt stay on the tool and can be disposed safely
