TTSh-35 heat shrink tubing for busbar insulation rated for up to 35 kV
Type: TTSh-35 (TU 2291-049-97284872-2012)
- Designed for insulation of copper and aluminum busbars in electrical substations and switchgear cabinets. Can be installed outdoors
- Shrinkage ratio: 2.5:1
- Operating voltage: 35 kV
- Material: polyolefin, halogen-free
- Equivalents: BBIT (Raychem); BBI (3M)
- Resistant to tracking and UV radiation
- High dielectric strength
- Color: Brick red
- TSh tubes allow to reduce the distance between the phase buses and significantly reduce the dimensions of the device design
- The tubes protect electrical busbars against chemical corrosion
- They protect the equipment from short circuits resulting from animals and birds coming into contact with the switchboard
- Installation tools: TT-1800 heat gun or PG burners
If two tubes of different sizes can be installed on the desired busbar, choose the larger one
