2021 China New Design Bimetal Shear Bolt Connector - stepless shear bolt connectors – Waxun

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.  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
