Prysmian BICON Cable Joints

For many years, BICON has been in the forefront of jointing technology, from designs using bituminous filling compounds, to the development of the highly successful BICAST acrylic resin jointing system.

Most recently, we have supplemented these ranges with heat shrink and pre-moulded products (BIMOLD). We can now offer a unique package to satisfy all requirements.

All four systems are available at voltages up to or above 33 kV. Depending on application, each may offer benefits over the others.

For instance, termination of high voltage polymeric cables requiring the facility to disconnect or add in additional cables at a later stage, means that BIMOLD is the logical choice. Likewise, BICAST provides a fast, comprehensive jointing method with a versatile range covering low and high voltage and all cable types.
