    Explosion-proof cable entry KNVTN with external thread

    Explosion-proof cable entry KNVTN with external thread Explosion-proof cable gland KNVTN with external thread - image 2

    Product Description

    The KNVTN is an explosion-proof cable gland with Ex d protection, specifically designed for connecting unarmored cables when installed in conduits in hazardous areas. The gland's external thread design ensures secure cable retention and a watertight connection to the pipeline, maintaining system integrity and the required level of explosion protection. This design allows for the integration of cable lines into conduits, which is particularly important for installations with high mechanical strength requirements.

    Advantages

    • Optimal solution for systems with pipe wiring.
    • Sealed and safe connection of cable to pipeline.
    • High resistance to mechanical stress and vibration.
    • Versatility of application: can work with various types of cables.
    • Reliability and durability in aggressive environments and a wide temperature range.
