Short Description:

The raw material of the silicon core tube substrate is high-density polyethylene, the inner layer used a lowest friction coefficient silica gel solid lubricant. It is corrosion resistance, smooth inner wall, convenient gas blowing cable transmission, and low construction cost. According to the needs, different sizes and  colors of  small tubes  are concentrated by external casing. The products are applied to optical cable communication network system for freeway, railway and so on.
