FIELD: measurement equipment.SUBSTANCE: invention relates to equipment for measurement of cable parameters and may be used to measure stiffness of optical cables with high rupture strength under low temperatures. Substance: one end of a sample of an optical cable is fixed on the platform with the help of the first clamp, and the second end of the optical cable sample is bent from its axis by the angle ?>45° and is fixed on the platform with the help of the second clamp, afterwards the platform with the cable sample on it is placed into a climatic chamber, setting the specified temperature in it, under which they measure the radius of optical cable bend at the outlet from the first clamp. Previously for the same values of the angle ? and the distance 1, under normal temperature they measure relative radii of bend at the outlet from the first clamp Rand R, for two samples of the optical cable, for which stiffness values under normal temperature Band Bare available and differ from each other, afterwards for the same values of the angle ? and the distance 1 they make the measurements of the relative radius of the bend at the outlet from the first clamp of the tested sample of the optical cable Rat the specified low temperature. The relative radius of the bend is determined as the ratio of the radius of optical cable bend at the outlet from the clamp to the radius of the optical cable, and stiffness of the tested sample of the optical cable at the specified low temperature Bis determined according to the dependence.EFFECT: expanded area of application and reduced costs.3 dwg |
