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 preventcorrosion, contamination, flashoveroccurs, increase insulation margin, effectively shortening the distance between thestage, the pole distance, create favorable conditions for switchgear compact design.
