With the rapid growth of optical communications, the application of greentelftth Fiber Optic Splice Closure is more and more extensive. More and more new optical cable lines are being built, and the fiber optic splice closure is widely used in the access network line except for the core backbone network in the province and the province. It is flexible in use and plays a good role in connection and division of optical communication lines.
The fiber optic splice closure is an indispensable part of the optical cable communication line. Its main function is to realize the connection and disagreement of the fiber optic splice closure; at the same time, in order to ensure the grounding function of the fiber optic splice closure, the internal grounding device and the grounding portion of the optical cable must be electrically connected, and the metal components and grounding device of the fiber optic splice closure should be ensured. The cable reinforcement cores are insulated from each other to avoid adverse effects from the environment on the fiber optic splice closures. Fiber optic splice closures, like fiber optic cables, have their own quality and play a vital role in the transmission of communications.
Most of the Fiber optic splice closures are used in areas where high levels of lightning and wet weather occur. The requirement for the insulation and lightning protection of the Fiber optic splice closure is very high. It is suggested that the combination of the upper and lower insulating spacers of the Fiber optic splice closure can form insulation between the metal components of the Fiber optic splice closure and the optical fiber cable reinforcing core ( the fixing bolt). It is required that the "voltage withstand strength" of the Fiber optic splice closure is up to 15 kV DC voltage, and no breakdown or arcing occurs within 1 minute. It is recommended to install a professional and reliable lightning protection grounding device to ensure reliable internal electrical connection between the grounding device and the grounding portion of the optical cable. The connection resistance is less than 0.1Ω.
