Cable blowing machines are special machines for laying fiber optic cables in protective tubes in cable ducts using compressed air or water. The Kabeleinblasverfahren (engl. Techique cable blowing) is compared to the pulling cables cost-effective, and there are less tensile forces on the cable. A cuff piston is attached to the cable tip for blowing in.

Structure of the blowing device

The blowing machine ( cable blowing machine or fiber blowing machine ) consists of the following components: a head piece, which ensures the secure attachment of the protective tube into which this cable is blown and the supply of air pressure or water to this tube, whereby the Cable is inserted over the head piece and several seals into the conduit, which do not allow the penetration of air or water to the blowing device; a cable encoder that specifies the cable to the head piece; a base plate (mounting frame) on which the individual parts of the blowing device are built; a cable guide in which the cable is guided to the head piece with the aid of sleeves or rollers; a compressed air or water connection for the safe and safe supply of compressed air or water to the blowing device; a counter that shows the total length (optionally also the speed) of the blown cable, and a cable control unit that controls the speed of the cable to be inserted and the contact pressure of the cable transmitter.

Types of blowing equipment

Blowing devices can be categorized according to various criteria. For example, according to the size of the cable (common sizes start with an outer diameter of 10 mm, micro cables are smaller). They can also be differentiated according to the type of cable encoder: with roller, chain or belt drive or entirely without cable encoder. The drive motor can also be a distinguishing criterion, a distinction being made between pneumatic, hydraulic or electric motors.
