Medium voltage heat shrink tubing
KeHong manufacture medium voltage heat shrink tubing for 20 Kv copper bus bar, and also produce low voltage and high voltage bus bar heat shrink tube, there are many technical requirement during busbar tubing installation.
The busbar heat shrinkable tube will appear below problem before use:
The surface scratches usually happened during the copper production, storage and handling process, resulting in burr. If the busbar heat shrinkable tube was set on copper bar with burr, the heat shrinkable sleeve will be scratched, so heat shrinkable busbar tube will be cracking or cracking after running for a period of time.
During heating the tubes, the heat shrinkable tube mainly depends on the huge internal stress to achieve the purpose of shrinkage, and the heat shrinkable tube in the heating state is soft, so it is easy to be scratched, before the heating, please be sure to ensure copper busbar without burrs.
