    Explosion-proof cable entry KNVM for unarmored cable in a metal sleeve

    Explosion-proof cable entry KNVM for unarmored cable in a metal sleeve Explosion-proof cable gland KNVM for unarmored cable in a metal sleeve - Figure 2

    Product Description

    The KNVM is an explosion-proof cable gland with Ex d protection, designed for connecting unarmored cables in metal sleeves to electrical equipment operating in hazardous areas. The gland's design ensures secure attachment of the metal sleeve, a tight seal, and maintains the required level of explosion protection during operation in harsh conditions. This design is ideal for use in areas subject to increased mechanical stress and vibration.

    Advantages

    • Special design for connecting metal hoses.
    • Reinforced design, resistant to increased mechanical loads and vibrations.
    • A sealed connection that prevents moisture, dust and flame spread.
    • Versatility of use with various types of cables.
