Xiongan International Convention Center, as an important meeting place to guarantee a new area in the next 5-10 years, is an important part of the Xiongan International Hotel project. The Xiongan International Hotel project includes an international conference center, an international hotel and thirteen buildings for VIP receptions. The total investment is about 4.3 billion yuan!

In winter, due to cold air, the temperature in the New Shungang District can drop below-10 ° C, and the accumulation of snow exceeds 10 centimeters. If snow falls on the roof of the Xiong'an International Convention Center, it will not only affect the appearance but also pose a huge security threat. Therefore, snow and ice must be melted. After many comparisons, our heating cable has become a powerful tool for melting snow and ice on the facade of the Xiongan International Conference Center.

The external sheath of the special snow melting cable we offer is made of imported ptfe, which has obvious characteristics such as extreme frost resistance (-40 °C), heat resistance (65 °C) and UV resistance. The snow melting cable within ten years will not exceed 10%.

The snow melting system of this project uses self-heating cables that can adjust the output load based on facility conditions to maximize system energy saving.

1. Determine the number of heating wires according to the width of the gutter.

2. The snow cable is laid in the center of the gutter, and the heating cable is fixed on the surface of the gutter with a special fixing bracket, and the bracket is applied to the surface of the gutter with special glue.

3. Power distribution cables are laid along the network frame on the bottom surface of the roof, and the roof is broken from the side wall of the chute to exit into the outer chute, the perforation is sealed with a sealant.

4. Each junction box is equipped with a set of temperature control devices, and the temperature and humidity sensor is placed in the outer chute closest to the junction box.

The components and accessories of the snow melting system of this project mainly include: terminal box, passageway junction box and power junction box. The end box is used to seal the end of the heating cable, the pass-through connecting box is used to connect the heating cable itself, and the power connecting box is used to connect the heating cable and the power cable.

After processing the joints in the terminal box and the passageway junction box, since they are practically installed on the roof, all of them must be filled with insulating and waterproof silicone 704 to prevent water vapor and cause leaks, short circuits and other phenomena.

The power junction box is fixed on the outside of the trough (on the side of the covered horse track) via an externally treated bracket when mounted The bracket and iron plate are fixed by dovetail nails, and the power junction box and bracket are fixed by stainless steel cable ties.
