High Voltage Creepage Extenders. HVCE creepage extenders represent a long-term solution to pollution flashovers by making a permanent addition to the creepage distance. This increases flashover voltage, reduces leakage currents and surface electrical stresses. They are available to fit insulators and bushings up to 500 kV, with shed diameter 80 mm to over 390 mm. Wrap-around HVCE-WA creepage extenders are cold applied and custom-made from semi-rigid polymer and bonded in place with a pressure sensitive track-resistant mastic. These are available to fit insulators and bushings up to 500 kV.

Heat Shrink Insulation Tubing
Heat-shrinkable busbar insulation tubing. Busbar heat-shrinkable tubing are suitable for use on long runs of rectangular or round busbars. The tubing shrinks down to 40% of their original diameter and, due to excellent flexibility, conform tightly to a wide range of sizes. BBIT/BPTM tubing can be slid easily into place, even around several bends and awkward shapes. The wall thickness is controlled by heat-shrink process. Available for over fifteen sizes of busbars from 5 mm to over 250 mm, BPTM/RBPM is suitable for applications up to 24 kV. BBIT is suitable for applications up to and over 36 kV.

Medium Voltage Insulating Boots. Cold applied unscreened elastomeric insulating boots (in Silicon or EPDM) are moulded parts, fitted over the connection between a cable lug and inline or right-angled equipment bushing, to improve phase-to-phase and phase-to-ground insulation. They are used in switchgear and transformer cable boxes where the air clearances are insufficient for normal operation or protect against flashover due to rodents or high humidity. The non-tracking elastomeric housing has excellent erosion resistance, dielectric properties, and environmental resistance, giving superb performance in areas of high humidity and electrical stresses.

Medium Voltage Insulating barriers. BCIC preformed covers provide connections for insulators, bushings and busbars. Customized covers can be made simply and economically by vacuum forming non-shrinkable sheet material. Installation is very simple often with no need to disconnect busbars. BCIC covers are held in place with UV-stabilized plastic nuts and bolts, rivets or tie-wraps, and can be easily removed for maintenance, or else sealed with Raychem sealing mastic. Suitable for applications up 36 kV. Rigid Red Barrier Board (RRBB) is a non-structural, interphase barrier for switchgear applications. The RRBB board has excellent track resistance, especially following a power-arc. It can be easily fabricated into a shape; produces less nuisance dust and less tooling wear than other boards.

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.

Overhead Line Cover
Overhead line covers for bare conductors. MVLC provides state-of-the-art insulation to help prevent electrical outages. It is designed to insulate existing bare lines without costly conductor replacement expenditures or additional line hardware. MVCC provides high quality electrical insulation and made from non-tracking silicone material suitable for harsh medium voltage outdoor environments. MVCC is suitable for applications up to 25 kV phase to ground. Covers protect energized conductors from flashovers due to contact from birds and animals.
