    KOV Explosion-Proof Cable Glands with Double Seal for Armoured Cable

    KOV Explosion-Proof Cable Glands with Double Seal for Armoured Cable Explosion-proof cable glands KOV with double seal for armoured cable - Figure 2

    Product Description

    The KOV is an explosion-proof cable gland with an Ex d protection rating, designed for inserting armored cables into electrical equipment enclosures operating in hazardous areas. The gland design meets modern installation requirements, ensuring precise installation, tightness, and maintaining the equipment's explosion protection rating.

    Advantages

    • Modern technological design that speeds up and simplifies cable installation.
    • Reliable sealing prevents dust and moisture from entering the equipment.
    • High mechanical strength and vibration resistance during long-term operation.
    • Stable performance characteristics over a wide climatic range.
    • Protection against pulling out, without damaging the structure of the cable sheath and conductors.
    • KOV cable glands are included in the Register of Russian Industrial Products.

    Additional information

    KOV 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 KOV 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.

    The armor cluminaireing ring allows the KOV cable gland to be used with all types of cable armor/braiding: 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 KOV cable glands ensure ground continuity between the cable armor/braid and the gland body with a cluminaireing ring, providing protection against electromagnetic interference. Waterproof PG-GERMETIK insulation is used to protect the cable armor/braid from prolonged flooding. The cable glands comply with DTS01 requirements.

    Explosion-proof KOV cable glands are designed to relieve cable strain. These cable glands provide protection against cable pullouts without damaging the cable sheath or conductors, and prevent them from being pinched.
