Product Description

Heat Shrink Bus bar Protection Tubing

heat shrink bus bar protection tubing, HV heat shrink tubing, LV heat shrink tubing, HBBT

Model: HBBT

APPLICATION:

Heat Shrink Bus bar protection Tubing (HBBT) Provides high resistance to tracking and arching and used to enhance the insulation properties of bus bar in switchgear and substation. The continuous length of supplied products makes it to be used more conveniently and economically. Avoid short circuit fault caused by small animals such as mice, snakes and so on. Prevent bus bar from chemical corrosion effected by strong acid, alkali, salt, etc. Avoid accidental injure, for instance, that overhaul person enter electriferous clearance by mistakes. Be suit to the trend of smaller switch cabinets. Be applied in bus duct for insulation among buses.

COLORS: Red, Green, Yellow, Black(Other colors available on request.)
