FIELD: electricity.
SUBSTANCE: cable tension device is used in coiling machines for winding a thin optical cable onto a suspended carrier element. It is installed in the reel (2) of the cable coil and/or in the cable pulling roller. A device, rotated on a fixed shaft (9) by a coiling cable (5) comprises a spiral flat spring-accumulator (14), the inner end of which consists of several tight turns (15) tightly surrounding the shaft portion (12) forming an overtaking clutch. The outer end of the battery spring is engaged with the spring brake shoe (20), which is embedded in the brake drum (22), forms a friction pair of long-acting action with it.
EFFECT: creation of a tension device having low weight, which is a requirement for winding machines for the construction of aerial FTTH networks.
