PISL Series

MEDIUM VOLTAGE BUS-DUCT INSULATORS

for indoor installation

Bus-duct insulators series PISL for indoor installation are manufactured for rated voltages 12, 24 and 38 kV, and comply with IEC 60137. Bus-duct insulators are suitable for busbar conduction through metal sheet walls (thickness up to 5mm). They are made of high-quality epoxy cast resin compound.

Internal surface is made of conducting material, in galvanic contact with busbar system. Bus-duct insulators are equipped with aluminium plates for busbar-holding. Contact rings of spring wire hold the busbar holders at place and also provide galvanic contact between internal surface and busbars.
The insulators can be fixed at site by steel nuts (at versions PISL12 a, b) or fixing tubes (versions PISL12 c-g, PISL24, PISL38).
