    KNV Explosion-Proof Cable Glands for Unarmored Cable

    KNV Explosion-Proof Cable Glands for Unarmored Cable Explosion-proof cable glands KNV for unarmored cable - Figure 2

    Product Description

    The KNV is an explosion-proof cable gland with an Ex d protection rating, designed for inserting unarmored cables into electrical equipment enclosures operating in hazardous areas. The gland's 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.
    • KNV cable glands are included in the Register of Russian Industrial Products.

    Additional information

    KNV cable glands can be used for armored/braided cables. Sealing and grounding of the armor are performed outside the cable gland. The cable's inner sheath is inserted into the gland. To ensure continuity of the grounding circuit with the device's metal housing and protection from electromagnetic interference, an A32 grounding element is used.

    Explosion-proof cable glands KNV are designed to relieve cable strain, provide protection against pull-out without damaging the structure of the cable sheath and conductors, and prevent them from being pinched.
