Сигнальная лента «Осторожно кабель!» (ЛСЭ)
LSE signal tape is an effective and inexpensive way to identify an underground electrical cable. This tape fixes the place where the cable is laid and prevents the possibility of mechanical damage when doing earthwork in the future.
The use of a signal tape when laying cable power lines complies with the requirements of the PUE ed. 7, p. 2.3.83. According to the said "Rules", when laying power cable lines with voltage up to 20 kV in a trench with no more than two cables, it is allowed to use signal plastic tapes that meet the requirements approved by the Ministry of Energy of the Russian Federation. LSE is not used over cable sleeves and at the intersection of cable lines with other utilities at a distance of 2 meters on either side of the intersection. It is also not allowed to use it within a radius of 5 meters from switchgears and substations. In such areas, LZS should be used.
LLC "Brandlenta" offers to buy a signal tape for the identification of an electrical cable.
LSE characteristics and the procedure for its application
LSE - signal tape "Electra" of bright red color with a black inscription "Caution, cable!" in Russian and English, he will promptly inform the excavation workers about the presence of a cable line in the ground.
The tape is made of dense, durable and resilient polyethylene, which is resistant to temperature changes, high humidity and aggressive environments. The material does not decompose, does not rot, and is environmentally friendly. The tape is perfectly visible when opening the ground, it does not lose its properties and color saturation over the years.
The tape is produced with a thickness of 300 microns. The width of the tape is selected depending on the cross-section of the cables and their number. Standard tape width 150; 250; 300; 450; 600; 750 and 900 mm. The tape is supplied in rollers.
In addition to the inscription "CAUTION: CABLE", the signal tape may have other markings: "Electric cable", "Do not dig below, cable!" or others, as well as the logo of the company that laid the cable.
FEL should be laid in a trench above the cable at a distance of 250 mm from its outer sheath. When laying one cable in a trench, the tape is located along its axis; with two cables, the edges of the tape should protrude at least 50 mm beyond the outer cables. When laying several belts across the trench width, adjacent strips should be overlapped with a width of 50 mm or more.
Signal tape is the most affordable, simple and effective means to attract attention and protect cable lines in the ground from possible damage.
