Explosion-proof cable entry KOVS with compound sealing

Product Description

The KOVS is an explosion-proof cable gland with Ex d protection, designed for inserting armored cables into electrical equipment enclosures operating in hazardous areas. The KOVS design utilizes a sealing compound, creating an additional protective barrier and increasing equipment reliability. This design is particularly effective when using cables with complex insulation structures.

Advantages

  • Enhanced explosion protection level due to cable sealing with compound.
  • Increased operational reliability when using cables with loose or non-standard insulation.
  • Eliminates the possibility of flame spreading through the internal cores of the cable.
  • Higher resistance to aggressive environments and extreme climatic conditions.

Additional information

An explosion-proof bushing for sealing with compound allows the cable entry to be used for inserting armoured cables of non-circular cross-sections or those with a structure where the wires do not fit tightly.

The grommet consists of two components: a sleeve and a release element. A two-component epoxy compound, included in the package, 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 the gland. In addition to its flexibility, the epoxy compound ensures high bond strength, does not shrink, and is resistant to water, oils, and solvents.

The armor cluminaireing ring allows the KOVS cable gland to be used with all types of cable armor/braiding: 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 cable glands KOVS ensure continuity of the grounding circuit between the cable armour/braid and the entry body with the armour/braid cluminaireing ring, and provide protection against electromagnetic interference.

Explosion-proof KOVS cable glands are designed to relieve cable strain. These cable glands provide protection against pull-out without damaging the cable sheath or conductors, and prevent them from being pinched.
