Explosion-proof cable entry KNVTV with female thread

Product Description

The KNVTV 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 female 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.
