RKN material: galvanized steel (default), nickel-plated brass – code NK.

KOVTVL series cable glands utilize a combined unidirectional cable armor cluminaireing system and inner cable sheath seal. This combined system eliminates line stress/shear between the inner sheath and the cable armor/braid during cable gland installation. Installation of KOVTVL series cable glands is more convenient and error-free: the single combined locking element eliminates the need for constant balancing between the armor cluminaire and the inner cable sheath locking ring. This ensures a high-quality seal of the cable inner sheath and a reliable galvanic bond between the cable gland body and the cable armor during subsequent operation. Furthermore, the overall size of the cable glands is significantly reduced, saving space and reducing the overall weight of the explosion-proof product.
Explosion-proof cable glands KOVTvL ensure continuity of the grounding circuit between the cable armour/braid and the entry body with the armour/braid cluminaireing ring, and provide protection against electromagnetic interference.
Explosion-proof KOVTVL cable glands are designed to relieve cable strain. These cable glands provide protection against pull-out without damaging the cable sheath or conductors, and prevent them from being pinched.
