    Product Description

    The RKN-ZK is an explosion-proof cable transition element with a threaded connection, designed for the entry and connection of flat or round electrical wires and optical cables between the enclosures of Ex-rated equipment (e.g., between Ex d and Ex e or between two Ex d equipment). The connection is sealed with a compound, ensuring the explosion protection is maintained.

    Advantages

    • Wide range of threads (NPT, metric M, pipe R, G) for various connection systems.
    • Available in nickel-plated brass, galvanized steel and AISI 304 stainless steel.
    • Operating temperature range from –60 °C to +135 °C (in cold versions up to –75 °C).
    • Transition cable elements RKN-ZK are included in the Register of Russian Industrial Products.
