BBIT
Heat Shrinkable Busbar Insulation Tubing (BBIT):
Raychem BBIT thick-wall, heat shrink tubing provides insulation enhancement and protection against flashover and accidentally induced discharge. Particularly useful in con fined spaces, Raychem BBIT tubing can be used on both circular and rectangular copper or aluminium busbars. The use of the BBIT tubing allows equipment designers the freedom to reduce air spacing between busbars such as in the manufacture of switchgear cabinets where space is at a premium. The BBIT tubing provides flashover protection up to 36 kV.
Features:
- Suitable for voltage upto 36kV, application ∅11-125mm.
- High flexibility ideal for curved or bent busbars without cracking or creasing.
- Excellent thermal emissivity means no busbar derating is required.
- Flame retardant and non-halogen based material.
- Exceptional insulation and long term reliability even at high continuous operating temperature.

HVBT
High Voltage Busbar Tape (HVBT):
Raychem HVBT heat-shrinkable tape is ideal for use on complex shapes and where busbars cannot be disconnected. Raychem HVBT tape shrinks 30% longitudinally while a factory-coated hot melt adhesive flows and seals the layers of tape during installation. As with other components in the system, the adhesive does not bond to metalwork, allowing easy removal for inspection and maintenance. Available in three widths: 25mm, 50mm and 100mm.
Features:
- A single layer of tape with two-third overlapped is suitable for 17.5kV AC voltage and dual layer for 36kV AC voltage.
- Wide operating temperature -40°C to 90°C.
- Excellent thermal emissivity means no busbar derating is required.
- Adhesive-coating produce complete lap to lap seal.
- Non Adhesive to metal or porcelain, allowing easy removal for maintenance.
MVFT
Medium Voltage Fusion Tape (MVFT):
For cold applied applications Medium Voltage Fusion Tape is also available which performs the same function.
Features:
- Silicone self amalgamating fusion tape.
- A single layer of tape with two-third overlapped is suitable for 15kV AC voltage and dual layer for 35kV AC voltage.
- Wide operating temperature 0°C to 90°C.
- Design to combine the integrity of a Silicone polymer with the versatility of wraparound product.
- It sticks to itself and other insulating material, it will not adhere to metal porcelain allowing easy removal for maintenance.
Creepage Extender
Creepage Extenders:
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.
Features:
- Increases creepage length
- Improves insulator shape
- Bonds to insulator surface
- Rugged
- Proven materials
- Simple to install

Raychem BPTM medium-wall, heat shrink tubing provides insulation enhancement and protection against flashover and accidentally induced discharge. Particularly useful in confined spaces, the BPTM tubing can be used on both circular and rectangular copper or aluminium busbars.
Features:
- Suitable for Voltage upto 25kV, application ∅6.5-150mm.
- Assured performance even at continuous high operating temperatures.
- Good thermal emissivity and contact with busbars means no derating is required.
