Snow Melting Cable
- Snow Melting Cable
- Snow melting system is an innovative ice- and snow-removing facility which buries heating cable at a certain depth under the pavement in order to automatically detect temperature and humidity when snow falls or ice occurs in the winter. Installed on places such as steep slope on roads, tunnel entrances and exits, and parking lot entrance for apartments, it helps safe walk and drive, reduces damage on buildings, and ensures safety of people, vehicles, and buildings.

- Durability
-
- Double insulation by silicone and Teflon ensures excellent durability.
- It is an eco-friendly product which is not caused worries for vehicle corrosion or reduction of road lifespan.
- Utility
-
- Can be used easily in narrow places or places where it is difficult to use ice-removing equipment
- Using KIT work (Cold Lead work), convenience of construction is maximized and defect rate is zero
- Economic feasibility
-
- Auto control method does not require snow-removing manpower when it snows or when ice occurs.
- No separate maintenance cost is required after initial installation.

Considerations when using snow melting cable
- 1. Does the heating energy consider the average temperature of the construction site?
- – Heating energy required for melting ice and snow according to average temperature and snowfall by region are shown below.
| Lowest average temperature (Jan. ~ Feb.) |
Snowfall (cm/hr) |
Road and street (W/m²) |
Bridge (W/m²) |
Stairs (W/m²) |
Port (W/m²) |
|---|---|---|---|---|---|
| -2℃ | 1.7cm | 170W | 200W | 170W | 250W |
| -6℃ | 2cm | 200W | 250W | 200W | 300W |
| -10℃ | 2.5cm | 250W | 300W | 250W | 350W |
| -15℃ | 3cm | 300W | 350W | 300W | 400W |
| -20℃ | 4cm | 350W | 400W | 350W | 450W |
- 2. Is there a clear understanding on incoming electricity?
- – Types and diameters of the cable vary by the type of incoming electricity.
- 3. Is the installation section designed with accuracy?
- – Required electricity ought to be calculated by accurate installation section.
- 4. Is the system installation technique confirmed?
- – Precise discussion and execution must be performed regarding installation technique.
- 5. Composition of SMP (Snow Melting Panel)
- – Auto control method suitable for the site prevents safety accidents against freezing and in heavy snowfall.
