RAYCHEM HTIT 72KV BUSBAR INSULATION TUBING
Description
TE Connectivity’s (TE) Raychem HTIT high voltage thick-wall, heat shrink busbar insulating offer improved insulation and protection against accidental induced discharge and flashover. These tubes are useful in confined spaces on circular and rectangular copper or aluminum busbars. They are applicable to both outdoor and indoor environments.
Our HTIT tubes feature an extra-thick wall of 5.1-5.2 mm, optimizing phase-to-phase and phase-to-ground clearance for highly compact equipment according to IEC 60071 for any applications where busbar insulation is up to 72 kV, such as in the manufacture of switchgear cabinets where space is at a premium. When heated, the tube shrinks snugly over the busbar profile to obtain the minimum required wall thickness. The HTIT tubes can be installed easily during large-scale production using an oven or in-field using a gas torch or hot air.
The BPTM tubes are manufactured from a halogen-free polymer with excellent performance in high-voltage environments, reducing the toxic and corrosive effects in fire situations. They offer exceptional insulation and long-term reliability, even at high continuous operating temperatures.
The tubings have good thermal emissivity, long shelf life, and storage temperatures of up to 50 °C without
performance loss.
