CYG-BT (1T/10M) is halogen-free, low smoke track-resistant polyolefin heat shrinkable bus bar sleeving. It is widely used to protect the rectangular bus bars found in low or medium voltage switching equipment.
Application: This product is widely used in low voltage switch cabinet bus insulation protection, effectively prevent personal injury or death caused by the charged row naked; to avoid a small animal and the conductor ride then cause a short circuit, discharge failure occurs, to prevent corrosion, contamination, flash over occurs, increase insulation margin, effectively shortening the distance between the stage, the pole distance, create favorable conditions for switchgear compact design.
