CABLE GLANDS

ГОРЭЛТЕХ производит кабельные вводы для всех видов соединений с различными типами резьбы. Широкий диапазон выпускаемых кабельных вводов позволяет решать всевозможные задачи по подсоединению различного типа небронированных и бронированных кабелей, кабелей с оплеткой, металлорукавов и трубной проводки в корпуса электротехнических аппаратов. For direct insertion of cables and wires to Exd enclosure, specially developed Exd glands for direct insertion are applied. 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. (former "CORTEM-GORELTEX" Co. Ltd.) unique compared with products of other companies.

Wide range of produced cable glands helps to solve multiple tasks of connection of various types of non-armored and armored cables, cables in sheath, flexible conduit and pipe conduit into enclosures of electrotechnical apparatuses.

Due to material of construction and special coating, our cable glands can be used in moist and dusty rooms and in highly aggressive ambient conditions. Cable glands are resistant to salt spray and other chemical substances, including hydrogens sulfide and hydrochloric acid vapors, saline and acidic mine waters. For full range of cable glands please follow website page "Explosion-proof cable glands". Interactive selection of an explosion-proof cable gland...>>

*Note:

  1. The table shows corrosion resistance of the enclosure material, its resistance to exposure caused by pollution, as well as ingress protection degree.
  2. When choosing the enclosure it is important to take into account the ambient environment where the box will be operated. It is especially important for enclosures which are used in hazardous areas, since the enclosure is the essential component of protection. The attention should be particularly paid to the consequences of the corrosion and presence of chemical substances in the atmosphere, as well as probable mechanical impact.
