To avoid physical injury and damage to buildings,
... the formation of hoarfrost and icicles on guy ropes must be prevented.
Cell towers used to receive and transmit radio and television frequencies are often constructed as narrow tubular towers with a diameter of around 2 metres and a height of up to 250 metres. The antennas required for the reception and transmission are located in protective cylinders on the mast. To stabilise the entire cell tower against potential wind loads, it is secured by guy wires. In most cases, guy wires are braced in three directions, which are offset from one another by 120 degrees when viewed from the top. Guy ropes often must be attached at different heights to achieve sufficient stability for the tower. For each level, three such guy ropes are attached around the tower at an angle of 120° each. In general, they are anchored to the ground with solid concrete foundations.
Weather-related environmental effects involving high humidity and cold temperatures can lead to the formation of large hoarfrost area and icicles. If these fall down as a result of strong winds, they pose a major risk to people and neighbouring buildings. By using electrical heat tracing, the formation of hoar frost is prevented, thus ensuring maximum safety.
An electrical heat tracing system installed on the guy wires of a radio tower increases safety,
... because hoarfrost or icicles don't get a chance!
To prevent the formation of hoarfrost or icicles under wet and cold weather conditions and thereby reduce the risk of accidents for pedestrians and motorists while protecting surrounding buildings, guy wires on cell towers must be heated.
For this purpose, a variant of the "EL-Rail" fixed resistance heating cable is utilised. In this case, it consists of nine serial resistance heating cables insulated with fluoropolymer to protect against moisture. The heating cable is attached directly to the guy wire. Thanks to the measurement and control technology used, the heating is controlled precisely and individually. The system offers high performance and has been operating smoothly and with low maintenance for a decade.
- moisture-resistant
- structural robustness
- durable and virtually error-free
- low need for maintenance
- high performance
FAQ
If hoarfrost or icicles dislodge due to wind at a certain height and fall down, they can cause bodily injury and damage to buildings. Vehicles in the vicinity can also be affected. To prevent this, electrical heat tracing systems are used along the guy wires.
To prevent hoarfrost and icicles from forming on guy ropes in the first place, the guy ropes must be heated. Thanks to the resistance heating cables used, high humidity and cold temperatures don't stand a chance. Our "EL-Rail" resistance heating cable heats the guy ropes - the measurement and control technology used determines the right time for heating.
