Explosion-proof cable glands are used on equipment where an explosion may occur, as well as at industrial facilities, in automation systems, electronics, robotics, in places where sealing of the IP 66/67/68 cable sheath is required.

Twisted pair is one of the components of modern structured cabling systems. It is used in telecommunications and computer networks as a physical signal transmission medium in many technologies, including Ethernet. Currently, due to its low cost and ease of installation, it is the most common solution for building wired (cable) local networks. The cable consists of several pairs of insulated conductors twisted together (with a small number of turns per unit length), covered with a plastic sheath. Aluminum foil and copper braid are also used to shield the cable and individual pairs for additional EMI protection. There are voids in the cables, which makes it difficult to use in explosive areas. Sometimes, the voids in the cables are filled with water-repellent gel, but this is not enough for safe entry, especially in Exd enclosures.

Explosion-proof cable glands of the Ethernet  series with a special seal are designed to enter 4-pair twisted pair in Exd enclosures.
