SIMABUS is an Extra high voltage range of clamps and connectors for AC & DC applications up to 500kV (phase-to-phase voltage) These products are designed to support and connect Ø80 to Ø250mm aluminium bus conductors to Copper or Aluminium Equipment Terminals.

The main technical benefit of this range is to offer compact connectors with high electrical and mechanical performances obtained by a design with optimized parameters.


  • Top electrical performances
  • High mechanical strengths of components
  •  High quality casting components
  • Components submitted to mechanical stress such as mechanical supports and keepers are advantageously die casted
  • The products have been designed to withstand actual mechanical strengths required in EHV Substations
  • The design of the products avoids any transfer of torsional moment to the Post Insulators or Terminal Equipment’s
  • FEM Calculation has been used to meet EHV connector design requirement
