Explosion-proof cable entry KOVTV with female thread

Product Description

KOVTV is an explosion-proof cable gland with Ex d protection, specifically designed for connecting armored 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 explosion protection level. 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.

Additional information

KOVTV series cable glands utilize a combined unidirectional cable armor cluminaireing system and inner sheath seal. This combined system eliminates line stress/shear between the inner sheath and the cable armor/braid during cable gland installation. Installation of KOVTV series cable glands is more convenient and error-free: the single combined locking element eliminates the need for constant balancing between the armor cluminaire and the inner sheath retaining ring. This ensures a high-quality seal of the cable inner sheath and a reliable galvanic bond between the gland body and the cable armor during subsequent operation. Furthermore, the overall size of the cable glands is significantly reduced, saving space and reducing the overall weight of the explosion-proof product.

The armor cluminaireing ring allows the KOVTV cable gland to be used with all types of armor/braiding: single-wire armor, braided armor, tape armor, and wire armor. An external sealing ring for IP protection prevents moisture from entering the cable gland, which could damage the armor/braiding.

Explosion-proof KOVTV cable glands ensure ground continuity between the cable armor/braid and the gland body using a cluminaireing ring. Waterproof PG-GERMETIK insulation is used to protect the cable armor/braid from prolonged flooding. These cable glands comply with DTS01 requirements.
