NIKOLAN 4 Series cables provide excellent performance at a reasonable price, which makes them the best choice for building networks in projects that do not require system support. The range of internal cables includes shielded (F / UTP) and unshielded (U / UTP) cables of categories 5, 5e and 6 with PVC or LSZH-comand shells. Depending on the specific model, the internal cables of the 4th series are delivered in “easy-pull box” cartons or on plywood drums. Unshielded cables (U / UTP) are the most popular and easy to install type of cable, but they do not have protection against electromagnetic interference. When laying in close proximity to the power lines, it is recommended to refer to shielded solutions.
