Shearbolt Connectors (pre-assembled screw) Properties

  • Screw Material: brass for minimum friction
  • Partition
  • Pre-assembled shear-off screws for easy handling
  • Voltage Range: 1kV.
  • Meets the requirements of standard IEC 61238-1.
  • PEN is a filler piece for use when connecting the cable’s copper screen.

General Information

Elpress shearbolt terminals are available as through connectors and terminals for:

  • stranded and solid Al and Cu cables
  • round cross section 10 to 630mm2
  • sector cross section 16 to 240mm2

The screws used are made of brass, which offers a lower friction compared to aluminium or steel. This makes it easier for the user to install. Installation tools can be a socket wrench or an impact wrench with torque force > 100Nm. We recommend that the fitter uses a counterhold toolto secure the shearbolt terminal more easily when tightening the screws.

The following apply for bright galvanised type nuts and screws, with strength class 8.8, used for connecting terminals with Cu and Al palms:

  • Always use a torque wrench to be certain the right torque is achieved. Ensure it is calibrated regularly according to supplier’s instructions.
  • Use the recommended torque according to the screw manufacturer’s instructions.
  • Always use a hard flat washer to reduce friction against the connection surface and the edge pressure, hardness min HB200.

Labelling & Tightening

Elpress marking of shearbolt terminals shows logo, product name, cable area (for stranded and solid conductors) and installation order. The terminal palmis marked with screw size M-thread for bolted joints.

Recommended tightening torque for wet lubricated screws and nuts of bright galvanised zinc type with strength class 8.8 and coarse threaded (normal thread), used with corresponding washer for connection of terminals with Cu- and Al palm.
