Insulating Tapes FullScreen

Medium Voltage Heat Shrink/ Fusion tapes. HVBT heat-shrinkable tape is ideal for use on complex shapes and where busbars cannot be disconnected. HVBT tape shrinks 30% longitudinally and an adhesive layer flows and seals the layers of tape during installation. As with the other components in the system, the adhesive does not bond to metalwork, allowing easy removal for inspection and maintenance. Available in four widths from 25 mm to 100 mm. A spiral formed tape is also available for ease of use on overhead conductors. MVFT is a self-amalgamating tape providing insulation enhancement and protection against accidentally induced discharge. Quick and easy to install, upon application the tape amalgamates the overlapped layers together, producing a complete seal.
