When the optical cable is subjected to external force or environmental temperature change, the optical cable generates tensile or shrinkage strain. By adopting the cable core structure of loose-sleeve layer twisting, when the optical cable is stretched (or contracted), the length change of the optical fiber which moves from the center of the loose sleeve to the inner side (or the outer side) compensates the change caused by the extension (or the contraction) of the optical cable, and the optical fiber in the loose sleeve is ensured not to be acted by force, so that the 'extra length' formed after cabling is of great importance, and the attenuation performance, the tensile property and the temperature characteristic of the whole optical cable are directly influenced.

Detailed Description
The present invention will be described in further detail with reference to the following embodiments.
As shown in fig. 1, the constant temperature stranding cage device in this embodiment includes a stranding cage and a warm air structure disposed in the stranding cage, the stranding cage is divided into three regions due to a long and narrow space of the stranding cage, each region is provided with the warm air structure, the warm air structure is disposed on a side surface of the stranding cage and is used for providing warm air circulation in the stranding cage region, so as to maintain a constant temperature environment, a temperature measurement point is disposed on the other side surface opposite to the warm air blower, and the temperature measurement points of the three regions are respectively connected with temperature control meter signals corresponding to the three regions.
The warm air structure comprises a mounting support 4, a cross flow fan 1, PTC ceramic heating sheets 2 and a hot air guide plate 3, wherein the cross flow fan is supported on the mounting support 4 and is emptied relative to the ground, an air inlet screen 8 is arranged on the side surface a of the mounting support 4, the cross flow fan is provided with an air inlet 5 for air inlet on the side surface, the air inlet 5 is right opposite to the air inlet screen 8, and cold air is sucked from the side surface a. The cross flow fan is provided with an upward air outlet 7, the PTC ceramic heating sheets 2 are arranged at the air outlet 7 and generate heat after being electrified, cold air sucked by the cross flow fan is heated at the air outlet 7 to become hot air, the PTC ceramic heating sheets 2 are provided with mutually parallel slits and generate resistance to the hot air, hot air with pressure is generated, and the flow speed is improved. The hot air guide plate 3 is in an inverted U shape, and a hot air outlet 6 is arranged on the side face a to form a hot air outlet channel facing the inside of the stranding cage.
For accurate temperature control, the whole stranding cage is divided into three areas: the device comprises a first twisting cage area, a second twisting cage area and a third twisting cage area, wherein a PTC (positive temperature coefficient) fan heater, a temperature measuring probe and a temperature control meter are respectively arranged in each twisting cage area. Taking the first area of the stranding cage as an example: firstly, pressing a start button on a temperature control instrument of a zone, enabling a cross flow fan in a PTC (positive temperature coefficient) heating machine of the zone to work, enabling the temperature control instrument of the zone to start working, feeding back real-time temperature of the zone to the temperature control instrument by a temperature measuring point of the zone, outputting a heating signal by the temperature control instrument of the zone when the feedback temperature is lower than a set temperature, enabling a PTC ceramic heating sheet of the zone to start heating, enabling cold air to enter the PTC heating machine through an air inlet, blowing the cold air onto the PTC ceramic heating sheet by the cross flow fan, and inputting hot air into a winch cage through a guide plate after the cold air is heated by the PTC ceramic heating sheet; when a temperature measuring point in one area detects that the temperature of the first area of the stranding cage is close to the set temperature, the temperature control meter in the one area intermittently outputs heating signals, and the closer to the set temperature, the lower the frequency of the heating signals output by the temperature control meter is, which is the constant temperature principle.
