Pre-insulated Bushings Are Mainly Used At The Transition Between Cables And Busbars.

At the cable termination and busbar connection points, pre insulated sleeve is matched to different conductor sizes according to specifications and installed via mechanical crimping or specialized equipment. During installation, the sleeve must be placed along the conductor direction, ensuring its centerline aligns with the conductor's direction, which facilitates a stable contact interface between the metal terminal and the conductor.

Common insulation methods for busbars include insulating sleeves or heat-shrinkable material coverings, but using pre insulated junction sleeve at connection points simplifies construction steps and reduces on-site processing. The outer insulation layer of insulated joint sleeve is generally made of weather-resistant material, adaptable to various indoor and outdoor operating conditions, and compatible with different cable and busbar system configurations.
