The SI-22 insulated sectors are to be used while performing works on electricity poles under voltage . They can be used as upper sections of aluminium ladders for DRS-1 or DRN-22 pole types, or as insulated ladders composed totally from SI-22 insulated sectors.
SI-22 sectors are made from foam filled glass-EP pipes. Such sectors ensure strong and simple construction allowing for easy assembly/disassembly on a pole.
