The base material of the silicon core tube is high density polyethylene, and the inner wall of the tube is a silicone solid lubrication layer with low friction coefficient. Corrosion resistance, smooth inner wall, easy to blow through the cable, low engineering cost. According to the requirements of the use of different numbers and colors of the tubular by the external sleeve together. Products used in highway, railway and other optical cable communication network system.

  The production line can realize simultaneous high speed unwinding of multiple base tubes and fast and uniform coating of extruded outer protective casing. Synchronous traction, cutting and finished product winding are centralized controlled by computer, with high production speed and efficiency.
