The protection procedure is related to the exposure of the line to direct lightning discharges and includes the selection of cable characteristics/installation, use of shield wires, bonding/earthing of the cable shield, installation of surge protective devices (SPD) and.

Eupen Pipe is producing PE and PVC pipes for the protection of cables and wires. They can be used in all areas of general construction and civil engineering, in road construction and also in the construction of tunnels and tracks. Our cable protection solutions offer excellent mechanical resistance. Here is a quick breakdown of the cable types that show up on modern construction projects. Low Voltage Copper Cables The bulk of low voltage work on most projects involves copper cabling. The most common types include: Cat5e - Still functional for basic networks up to 1 Gbps, but it is increasingly. Fiber optic cables enable high-speed, long-distance data transfer, forming the backbone of modern communication. Yet, outdoors, they face temperature swings, moisture, UV exposure, rodents, and human interference. Protecting them is essential for long-term reliability.
