Обзор
The YOCL ELECTRIC BDM-1 Ex e Unarmoured Cable Gland uses single compression construction for non-armored elastomer- and plastic-insulated cables in indoor and outdoor industrial applications. It may also be used with braided cables where the braid and outer sheath pass into the enclosure.
A claw-type clamping arrangement secures and seals the cable. The rounded entry helps reduce the risk of cable damage during insertion. The supplied marking is Ex eb IIC Gb and Ex tb IIIC Db.
