PURPOSE AND SCOPE OF APPLICATION
KNVM series cable glands with possibility to connect a flexible metal hose ensure explosion-proof sealing of cable outer sheath and environmental protection at the same time, excluding air circulation and ensuring reliable fastening of the metal hose. The structure of KNVM series cable gland comprises an adapter for direct connection of the metal hose thus eliminating the need to select it.
The most important development is the use of one sealing ring for the whole range of diameters of crimped cable, which reliably crimps the incoming cable and ensures Exd type of protection. One sealing ring together with mandrel or cable withstand the force in newtons, which is equal to the twentyfold diameter value (in mm) of the mandrel or the cable. This helps to use KNVM explosion-proof cable glands without additional unloading of cable.
KNVM series cable glands comprises dimension types with standard and increased ratio of diameter of crimped cable to inside diameter of the metal hose.
Increased wall thickness of bodies of GORELTEX cable glands considerably enhances their strength compared with cable glands of other manufacturers.
KNVM explosion-proof cable glands are suitable for use with equipment having ExnR marking.
Thanks to their design, KNVM explosion-proof cable glands ensure cable unloading, protection against pulling out without causing damage to the structure of cable sheath and conductors, as well as prevent cable overcompression.
Explosion-proof cable glands of KNVM series are designed in Russia (Patent No. 155936, rightholder "ZAVOD GORELTEX" Co. Ltd. , operating characteristics of which significantly surpass Russian and foreign analogues.
Scope of application – outdoor and indoor hazardous areas as per explosion protection marking, GOST 30852.13-2002 (IEC 60079-14:1996), dangerous production facilities of I, II, III, IV hazard class supervised by Rostechnadzor of the RF and national technical supervision bodies of the Customs Union and CIS countries.
