What is the role of a bushing in cable installations?

The role of a bushing in cable installations primarily involves providing insulation. Bushings are installed at points where electrical conductors enter or exit a piece of equipment, such as transformers or switchgear, ensuring that the high-voltage conductors are insulated from the grounded parts of the equipment. This insulation is critical for safety and the efficient operation of electrical systems, as it helps to prevent electrical arcing and short circuits that could lead to equipment failure or safety hazards.

The effectiveness of a bushing in insulating electrical components makes it vital for safeguarding both personnel and equipment by maintaining proper electrical isolation and preventing accidental contact. In addition to insulation, bushings may assist in providing mechanical support, but their primary purpose remains focused on electrical insulation.
