Heat Shrink Tape (Bustape)
Bus Tape is heat shrinkable tape specifically designed for insulating and protecting medium voltage Bus Bar Connections, where tubing can not be used.It is very conformable, tough, waterproof tape with special adhesive coating which bonds well to most surfaces over a wide range of temperature.The shrinking action achieves exceptional conformation to contours, squeezing the adhesive into all surface irregularities, forming an effective seal.
Features and Benefits
- Meets ANSI C37.20.2 standards for MV switchgear application up to 36 KV.
- Reduces Bus Bar clearance requirements.
- It is mainly used for insulating, anti-corrosive and mending purposes at the bending part.
- Protects against accidental flash-over.
- Highly resistant to UV ray and ozone.
- Halogen free & anti-tracking.
