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.
BPTM
Heat Shrinkable Busbar Insulating Tubing (BPTM):

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
EHV Dry Compact Switchgear & Transformer Termination
EHV Dry Compact Switchgear & Transformer Termination:
The dry compact switchgear termination for voltage classes up to 245 kV is designed to be installed in cable entry housings of gas-insulated switchgear (GIS). It complies with IEC 62271-209 standard, which essentially specifies the interfaces between the termination and the switchgear. Therefore the termination will fit into all GIS complying with IEC 62271-209. Adapters are available to match the dimensions of wet (oil-filled) type terminations, and older designs specified in IEC 60859. The termination operates in SF6 but also in insulating liquids like transformer oil.
Features :
- Dry interfaces, no oil-filling
- Dimensions comply with IEC 62271-209
- Pressure-tight resin housing
- Operates in SF6 and insulating liquids
- Pre-fabricated and factory tested
- Si-rubber stress cone
- Torque controlled or wedge-type multi-contact conductor bolt
- No special tools required to install the termination Isolated cable gland for sectionalization
- Type tested according to IEC 60840, IEC 62067 and IEC 62271-209 standards
