The maximum permissible number of wires, depending on the core cross-section, for sealing in a bushing.
The specified values correspond to clause 2.1.2, Appendix "C", GOST IEC 60079-1-2011.
Options
Additional information
An explosion-proof bushing for sealing with compound allows the cable entry to be used for inserting unarmored 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.
Explosion-proof KNVS 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.
