| Why do we have to use phosphate steel wire for optical cable | |
According to the industry standard, the young's modulus of the steel wire shall not be lower than 190gpa, the young's modulus of the steel wire shall not be lower than 170gpa, and the non-metal reinforcement shall not be lower than 50gpa, while the requirements of the optical cable with large structure and core number are higher, which needs to meet the short-term and long-term pulling requirements of certain type of optical cable. Precautions for use: ·During transportation, it shall be handled with care to prevent impact and damage to the outer package; it shall be kept away from moisture and rain, and stored in a dry and ventilated place. ·In the process of use, I-shaped wheel shall be used for setting out, and pay attention to the direction of setting out to avoid additional stress. ·During field use, pay attention to the running direction of wire rope to avoid additional stress and bending of wire rope. Phosphating steel wire for optical cable is divided into metal and non-metal models, which can be made of single steel wire or high-strength steel wire, while non-metal optical cable is generally made of FRP. The use of reinforcement of optical cable is determined according to the model of optical cable, and the specification of reinforcement is determined according to the requirements of tensile strength of optical cable. | |
