    Cable entry KNVTVS with compound and female thread

    Cable entry KNVTVS with compound and female thread KNVTVS cable entry with compound and female thread - image 2

    Product Description

    The KNVTVS is an explosion-proof cable gland with Ex d and Ex e protection types, designed for connecting unarmored cables when installing pipework in hazardous areas. Its female thread and compound sealing ensure a secure connection to pipelines, complete containment of any potential flame within the gland, and an additional safety barrier. This design is particularly popular when using cables with complex or loose insulation, as well as in environments with increased explosion protection requirements.

    Advantages

    • Eliminates the possibility of flame spreading through the cable cores.
    • High resistance to mechanical stress, vibration and aggressive environments.
    • The optimal solution for operation in extreme climatic conditions.
    • Increased operational reliability when using cables with loose or non-standard insulation.

    Additional information

    A two-component epoxy compound, included in the kit, is used as a sealant. The main advantage of using this compound, as opposed to liquid compound, is its flexibility, which facilitates cable installation. In addition to its flexibility, the epoxy compound provides high bond strength, does not shrink, and is resistant to water, oils, and solvents.
