Explosion-proof equipment plant
Explosion-proof high-voltage power boards are made in the form of suspending structure consisting of the main enclosure and indicating enclosure connected with each other. Explosion-proof boards are equipped with a voltage indication device.
For direct insertion of cables and wires to Exd enclosure, the following specially developed Exd glands for direct insertion with sealing are applied: KNV, KOV, KNVTN, KNVTV, KNVM series and with encapsulation KNVZ series. According to the mandatory requirements, this characteristic is specified in the certificate. This helps to refuse from inlet junction box (except for mining version РВ), which makes the products of "ZAVOD GORELTEX" Co. Ltd. unique compared with products of other companies.
Scope of application – outdoor and indoor hazardous areas of I, II, III, IV hazard classes as per explosion protection marking, GOST 30852.13-2002 (IEC 60079-14:1996), regulating application of electrical equipment in hazardous areas and areas with presence of combustible dust as per GOST 61241-3-2011.
X sign placed after Ex marking indicates that it is prohibited to use the device in hazardous mixtures of acetylene with air.
