Prysmian BICON BX1-3kg Bucket Electrical Joint Compound (U8644201)

Product overview

Prysmian BICON BX1-3kg Bucket Electrical Joint Compound (U8644201), like all BICON Inhibitor compounds, is designed to prevent galvanic corrosion and to enhance connections in electrical joints. It is especially effective when used on copper to aluminium and aluminium to aluminium connections.

Prysmian BICON BX1-3KG – General Information

In general, BICON Inhibitor compounds consist of a liquid base vehicle in which zinc particles are suspended. The base vehicle is a natural or synthetic grease which prevents water and other contaminants from influencing the connection and prevents the formation of surface oxides. The zinc particles help to break down existing oxide on the conducting surfaces when those surfaces get together under pressure. These particles form electrical bridges which improve the connection.

BX1-3kg Bucket Electrical Joint Compound (U8644201) has a natural (petroleum) grease base. It is ideal for all bare outdoor applications because of its excellent weathering properties. This petroleum base reacts chemically with rubber insulation and to a lesser degree with polyethylene insulation. The result is swelling and a reduction in the tensile characteristics of the insulation material. If the installer takes reasonable care to remove any excess from a connection, the resulting effect on insulating material is negligible.

Our experience shows that BICON BX1 Bucket Inhibitor Compound enhances the performance of electrical connections, particularly in aluminium to aluminium and aluminium to copper joints. The compounds, in bulk, are highly resistive, however, when applied as a thin film, with the aid of zinc particles, they decrease the contact resistance of a joint.

BX1-3kg Bucket Electrical Joint Compound (U8644201) – Use

  • Necessary in all aluminium to aluminium and aluminium to copper joints. The contact surfaces of the elements to be joined should be thoroughly scratch brushed. Liberally apply BICON BX1-3KG and remove any excess, after securing the joint.
  • Suitable for use in all applications where installer will not apply insulation to the joint, such as substations and switch-gears.
