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 line bushings are designed to connect Ethernet cables between two shells of explosion-proof equipment. Line bushings can usually be used between an Ex d enclosures and an input Ex e enclosures, or between two Ex d enclosures.

Line bushings are made of stainless steel, easy to install, and have a sturdy design for long-term use. Line bushings are installed in the body using metric threads.

One or two CAT 7 or CAT 5e Ethernet cables can pass through the separating line bushings.

Line bushings on both sides are equipped with industrial Ethernet cable and industrial GG45 or RJ45 connectors. The GG45 or RJ45 connector allows for easy and safe hot-plug installation in open Ex d enclosures or Ex e enclosures.

For high-speed applications, CAT 7 industrial Ethernet cable, type STP and S/FTP are used, which provide data transfer rates of up to 10 Gbps. Line bushings with Ethernet cable and CAT7 GG45 connectors provide high-speed communication in hazardous areas where safety and reliability are critical.

For data transmission, an industrial CAT 5e Ethernet cable is used, a type of UTP, which provides data transfer speeds of up to 1 Gbps. Line bushings with Ethernet cable and CAT5e RJ45 connectors provide communication in hazardous areas where safety and reliability are critical.
