The Pre-insulated Bushing Has Certain Flame-retardant Properties.

Typically, pre insulated sleeve undergoes specific flame retardancy testing to meet flame retardancy standards set by certification bodies such as UL Solutions. Through this certification, pre insulated junction sleeve flame retardant behavior includes resistance to continued combustion upon flame contact, minimal production of toxic or excessive smoke, and minimal dripping of molten material, thereby enhancing the overall safety standard of the cable system.

Using insulated joint sleeve in electrical equipment and cable systems provides an additional layer of protection for wiring and equipment in the event of abnormal heat sources, short circuits, or the initial stages of a fire.
