- Description
-
- Commodity name: Signal acceptance tower snow melting system
With the intensification of global climate change, extreme weather events such as snowstorms are frequent, which poses a huge threat to communication infrastructure. As an important part of the wireless communication network, the signal tower faces serious icing problems in winter, which will not only lead to the degradation of signal transmission quality, but may even cause serious accidents such as tower collapse.
► Application scenarios
With the intensification of global climate change, extreme weather events such as snowstorms are frequent, which poses a huge threat to communication infrastructure. As an important part of the wireless communication network, the signal tower faces serious icing problems in winter, which will not only lead to the degradation of signal transmission quality, but may even cause serious accidents such as tower collapse.
The snow melting system can effectively reduce the negative impact of snow and ice on the signal tower, and ensure the normal operation of communication facilities in adverse weather conditions. By actively melting snow and ice, equipment life can be extended and maintenance costs reduced.
►Composed of a snow-melting and ice-melting system
The main components of the snow melting and ice melting system: electric heat tracing control box, special electric heat tracing for snow melting, ice and snow sensor controller, power junction box, terminal junction box, special card for snow melting, weather-resistant fixing glue, fixed protection plate, snow melting fixed cable tie, etc.
System Advantages:
1. Cost-effective: The special electric heat trace designed and selected by our company for snow melting has a long service life, low maintenance rate and high heat transfer rate. The advantages of YATALO's special electric heat trace for snow melting: anti-aging material, long service life, low maintenance costs, low power consumption for long-term operation, and high heat conversion rate. We pay attention to the quality of each single product and the professional quality of system integration products, so as to achieve the effect of reducing costs and increasing efficiency in the real sense.
2. Safety guarantee: The main performance items of YATALO electric heating product manufacturing standards meet the GB/T19835-2015 standard, and the product materials are made of high-quality materials to ensure that the performance of electric heat tracing meets the standards, with good thermal stability, uniform heating temperature, heating temperature is within the standard range, will not overheat or short circuit lead to heat tracing combustion or burning, long service life, low attenuation of power meter, and high cost of replacement cycle due to short life.
► How it works
A snow and ice melting system typically consists of an electric heat tracing, a temperature sensor, an electric heat tracing temperature control box, and a power supply. Electric heat tracings are arranged along the cable and provide heat by means of electric heating. The temperature sensor monitors the temperature of the cable surface in real time and feeds the data back to the control unit. The control unit automatically adjusts the heating power according to the set temperature range to maintain the proper temperature of the cable surface.

► Construction and installation
1. Preparation
Site Survey: Detailed documentation of the structural characteristics of the tower, the surrounding environment, and historical snowfall. Particular attention is paid to snow and freezing conditions at the top of the tower and in the antenna area.
Formulate the plan: According to the survey results, formulate a detailed installation plan, including the selection and layout of the heating cable, the power access point and the configuration of the control system.
2. Installation Steps
Foundation construction: If required, the foundation of the receiving tower is reinforced or modified to ensure that it can withstand the weight and wind load of the new equipment.
Heating cable arrangement: According to the design scheme, the heating cable is evenly arranged in the snow-prone part of the signal receiving tower. Take care to keep the cables spaced and fastened to ensure that they transfer heat effectively. Power connection: Connect the heating cable with the power supply system to ensure that the circuit is safe and reliable. At the same time, sufficient power capacity is reserved for future expansion.
Control System Installation: Install control systems, including sensors, controllers, and actuators, in or near the signal receiving tower. Ensure that the system can monitor snowfall, air temperature and heating cable temperature in real time, and automatically adjust the heating power and working mode according to preset algorithms. Remote monitoring platform construction: Build a remote monitoring platform to realize remote monitoring and management of the snow melting system. Through the platform, managers can check the system status, adjust parameters and receive alarm information at any time.
3. Testing and acceptance
Preliminary Testing: After the installation of the system is complete, a preliminary test is carried out to check that the heating cables, power supply system, and control system are working properly. At the same time, the snowfall situation is simulated to observe whether the snow melting effect is as expected.
Full acceptance: After passing the preliminary test, a full acceptance will be carried out. The acceptance content includes the stability, reliability, safety and energy-saving performance of the system. Ensure that the system can meet the design requirements and usage requirements.
►Precautions and Recommendations
1. Precautions
Ensure that the insulation performance of the heating cable is good to avoid the occurrence of short circuit or leakage accidents.
Regularly check the wear and tear of the heating cable and replace the damaged cable in time. Ensure that the software version of the control system is up-to-date and regularly update software patches and bug fixes.
Regularly back up the data of the control system to prevent data loss or corruption.
2. Recommendations
According to the actual snowfall and usage needs, the heating power and working mode are flexibly adjusted to achieve the best snow melting effect and energy saving effect.
Strengthen the linkage and coordination with other devices to improve the reliability and stability of the entire communication system.
Constantly pay attention to the development of new technologies and methods, and introduce advanced technologies and equipment in a timely manner to improve the performance and efficiency of the snow melting system.
