BMC Contactor Insulation Barrier
The BMC insulator sleeve is made by compressing bulk moulding compound under controlled heat and pressure. It slips onto threaded studs at joint points, separating energised metal from earthed frames and adjacent components. Humidity and airborne dust are constant concerns at many power installation sites, and this sleeve holds up under continuous voltage load without easily forming conductive leakage paths on its outer surface.
Unlike thermoplastic alternatives, the material will not soften and deform if connection points see short heat spikes during normal operation. Its outer surface finish is formed directly in the mould, which reduces how much grime sticks to the part over months of service. Inner diameter, overall length, and wall thickness can be adjusted to match the stud size and creepage needs of individual switchgear or transformer terminal builds.
Samples pulled from each material lot go through voltage withstand and tracking resistance checks before full production runs start. These sleeves are fitted into terminal blocks, transformer bush fittings and indoor switchgear structures where reliable compact insulation around bolted connections is needed.
