The thermal softening temperature of the fiber optic splice box is greater than 90℃, and it can be used for a long time under the temperature of ﹣40℃~﹢60℃.
In the case of continuous operation of optical cable splice box equipment, the change of power supply is very normal, and the on-site environment is quite harsh, so lightning protection is extremely important. The quality of lightning protection measures directly determines the probability of failure of the cable junction box. However, it has become the main fault point in the distribution station area, and the damage and loss caused by it are many times that of other faults. The main manifestation is that in the peak summer, due to high temperature and heavy load operation, the connection of the incoming terminal of the watt-hour meter is loose and heated. , and due to untimely maintenance, short circuit is caused, and the entire junction box is burned.
In an objective aspect, since the use environment of Fiber Optic Splice Boxes Suppliers is basically outdoors, their use environment may be buried, overhead or pipeline. In order to prevent the influence of lightning strike or other factors, it is required that the "withstand voltage strength" of the optical cable splice box must meet the requirements of no breakdown and no arcing phenomenon within 1 minute after applying 15kV DC voltage in the standard.
The test after construction and deployment is to check whether there is any damage in the deployment process, in the two basic areas of the FTTP network - the interface between the feeder segment and the distribution equipment. Therefore, higher requirements are put forward on the design of the fixing and grounding devices of the optical cable splice box and the insulating materials used.
