KOVTV series cable glands utilize a combined unidirectional cable armor cluminaireing system and inner sheath seal. This combined system eliminates line stress/shear between the inner sheath and the cable armor/braid during cable gland installation. Installation of KOVTV 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 sheath retaining ring. This ensures a high-quality seal of the cable inner sheath and a reliable galvanic bond between the 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.
The armor cluminaireing ring allows the KOVTV cable gland to be used with all types of armor/braiding: single-wire armor, braided armor, tape armor, and wire armor. An external sealing ring for IP protection prevents moisture from entering the cable gland, which could damage the armor/braiding.
Explosion-proof KOVTV cable glands ensure ground continuity between the cable armor/braid and the gland body using a cluminaireing ring. Waterproof PG-GERMETIK insulation is used to protect the cable armor/braid from prolonged flooding. These cable glands comply with DTS01 requirements.
