Tapes signal (LS) are used as underground warning signals about grounded cable networks and pipelines. The signal tapes are made from a high pressure polyethylene composition with a warning text along the tape.
When carrying out excavation work on the sections of the pipeline and cable lines, the warning tapes warn of the communications pushed deeper down.
“Production Pack” produces the following types of signaling tapes (warning tapes):
- Do not dig! Lower power cable
- Caution! The cable is 1kW!
- Danger of gas!
- Communication cable
- Tapes signal connection
- Ribbons signal optics
- Signal gas tapes
The signal tapes are wound around the bobbins. The length of the drug in the skein is 500 or 1000 meters. The thickness of the tape can be almost anything, check with the manager.
Signal tapes have found application in the territory of Ukraine and the CIS countries, including on sites being built by foreign companies.
Fencing belts (zebra)
Fencing belts, the so-called zebra, are used in situations where it is required to protect or designate any territory. For example, places of work, places of incidents, zones of possible snow from roofs, other dangerous zones, as well as places for holding mass events.
Fencing belts are made of high-density polyethylene and very strong to break and stretch. Two types of fencing tapes are produced: “economy” and “standard”. Typical colors – red-white and yellow-black. The protective bands LO “Standard” have a thickness of 100 mkm and a width of 75 mm, the standard winding of the roller is 100, 250, 500 lm. LO “Econom” – 50 mkm, width 50mm or 75mm, the winding of the roller 200 lm.
Instruction on the use and laying of a tape alarm in trenches with power cables up to 35kW and control cables
1.1 The instruction is intended for organizations, regardless of the form of ownership, which performs work for the construction and operation of cable power lines with voltage up to 35 kV and control cables for various purposes that are laid in cable trenches.
1.2 The purpose of the instruction is to regulate normatively the requirements for the application and laying of the tape signal in trenches with power cables up to 35 kV and control cables.
The following terms and definitions apply to the instruction:
cable line is an electrical transmission line that consists of one or more parallel cables with connectors, end clutches and fasteners;
control cable – a cable to which control signals, measurement results or other process signals are transmitted;
tape signal – tape, usually polyethylene or polyvinyl chloride, of a corresponding color and with inscriptions, which is placed in trenches to prevent the location of the cable.
To determine the mandatory nature of the requirements, the Instruction uses the words “must”, “necessary” and derivatives from them. The words “as a rule” mean that this requirement is important, and a deviation from it requires justification. The word “allowed” means that such a decision is used as an exception (due to circumstances, limited resources, it is necessary to harmonize equipment, materials, etc.). The word “recommended” means that this solution is the best, but not necessary.
The cable that fits in the trench is protected:
– in accordance with the requirements of the PUE (§ 2.3.83);
– in accordance with the requirements of Chapter 2.3 of the PUZ-86 with changes to it in accordance with the decision of the Main Scientific and Technical Directorate of the Ministry of Energy of the USSR of June 10, 1990 No. 3-4 / 90 and GKD 34.21.206-2003 – taped signal.
