Explosion-proof equipment plant
"ZAVOD GORELTEX" Co. Ltd. manufactures cable glands for all types of connection with various thread types. 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 hydrogen sulfide and hydrochloric acid vapors, saline and acidic mine waters.
For full range of cable glands please follow website page "Explosion-proof cable glands".

For products with Exe type of protection terminals shall be of type Exe, for Exia products terminals shall be Exia.
Terminal shall correspond to wire cross-section (for spring terminal - to the type of clamp).
Maximum voltage and current of connected conductor shall be taken into consideration.
Type of DIN rail shall be taken into account (especially when it is required to install various terminals next to each other).
For boxes with Exe and Exia type of protection it is recommended to use terminals with copper and zinc alloy conductor, as they have the lowes power dissipation.
Operation of Exe terminal and wire clamping
In case of contact loss or increase of resistance on terminals due to incorrect installation or corrosion, devices with "e" type of protection become DANGEROUS for application. Electrical connections in Exe equipment shall be periodically checked and maintained in proper order.

Detailed information on explosion-proof terminals >>>
If it is necessary to install into the box terminals for a cable with different cross-section, the following formula shall be used for check when defining their approximate quantity:
where X, Y… - quantity of terminals of required cross-section;
A, B… - maximum possible quantity of terminals of this cross-section (refer to Table).
If inequality is fulfilled, then such arrangement of terminals in the given box is possible. Otherwise, the next size of box shall be chosen, and modular structure shall be used if maximum size is exceeded.
| Dimension type of the box |

*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.
