Model: CYG-MPG
Material: Radiation-crosslinked modified polyolefin
Shrink ratio: 2.5:1
Application
Low voltage heat shrink busbar insulation tubing can be widely used in the insulation protection of low-voltage switchgear busbar and effectively prevent the personal casualty accident caused by the exposed live part. Besides, it can avoid short circuit and discharge fault caused by small animals touching or wrong overlapping of conductor. At the same time, it can prevent the occurrence of corrosion, pollution and flashover, and extend insulation margin so as to effectively reduce distance between phase busbars, phase to ground distance and create good condition for miniaturization designation of switchgear cabinets.
