PURPOSE AND SCOPE OF APPLICATION

Explosion-proof terminal boxes KSRV are rectangular enclosures with cover made of modified corrosion-resistant aluminum-silicon alloy, resistant to salt spray and other chemical substances, including hydrogen sulfide and hydrochloric acid vapors.

Sealing system of explosion-proof boxes series KSRV has labyrinth shape, where seal is protected against environmental exposure, and due to that the enclosure has excellent degree of ingress protection IP66 which is confirmed by test results. Mounting holes located within perimeter of the box are arranged in such way that they are connected neither to labyrinth sealing system nor to fastening bolts of the cover. All fastening bolts are made of stainless steel which guarantees high reliability of fastening.

Inner and outer ground clamps are made of stainless steel and can be connected to mounting rail for terminals, mounting plate or earth bus bar. As aluminum is excellent conductor, grounding for cable glands is provided through contact with the wall of enclosure with no need to apply additional measures on provision of grounding circuit continuity.

Full production cycle starting from casting molds and to ready product is performed at the explosion-proof equipment plant “ZAVOD GORELTEX” Co. Ltd. (former “CORTEM GORELTEX” Co. Ltd.) on the territory of the Russian Federation.
