What key considerations influence the proper selection of cable glands for industrial applications?

The selection process for cable glands requires evaluation of multiple critical factors, starting with cable specifications: type (such as SWA armoured variants requiring specialized glands), core material, construction type, and cross-sectional dimensions. Environmental compatibility is equally essential, encompassing installation location constraints (space limitations, electromagnetic interference risks), ingress protection ratings (typically IP68 or IP69K for waterproofing), and hazardous area classifications necessitating intrinsically safe designs.   Mechanical requirements include bonding/earthing provisions, resistance to dissimilar metal corrosion (often addressed through nickel-plated finishes), and armour compatibility parameters for armoured cables—specifically inner bedding dimensions, armour material composition, and short-circuit current ratings. Connection specifications demand verification of thread standards (metric vs. PG7), mating component material compatibility, and inclusion of stopper plugs for unused entry points to maintain system integrity.
