BUSBAR INSULATION TUBING (BBIT)
VOLTAGE CLASS 36 kV, APPLICATION ? 11-125 mm
? Exceptional insulation and long term reliability even at high continuous operating temperatures
? Extremely durable, resists damage from solvents, ultraviolet light, weathering, mechanical impact
? Flame retardant and non-halogen based material reduces flammability and the toxic and corrosive effects in fire situations
? Good thermal emissivity and contact with busbars means no derating is required
KEY FEATURES
TE Connectivity’s (TE) Raychem thick wall, heat-shrinkable BBIT tubing provides insulation enhancement and protection against flashover and accidentally induced discharge. Particularly useful in confined spaces, Raychem BBIT tubing can be used on both circular and rectangular copper or aluminium busbars.
On application of heat the tubing shrinks snugly over the busbar profile ensuring that the required minimum wall thickness is obtained. Raychem BBIT tubing can be installed easily during large scale production using an oven or in the field using a gas torch or hot air. Raychem BBIT tubing is manufactured from a non-halogen based polymer which has excellent performance in high voltage environments and reduces the noxious and corrosive effects in fire situations.
The use of Raychem 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. Raychem BBIT tubing provides flashover protection
up to 36 kV.

CLEARANCE REDUCTION
The tables indicate the clearance
reductions which are possible using Raychem
BBIT tubing. These are derived from BIL, AC withstand, DC withstand and
discharge extinction tests. These clearances should not be adopted without
testing by the user. Sharp electrodes and unusual geometries may require wider
clearances.
