At present, greentel Fiber Optic Splice Closure has a wide range of applications, but the insulation problem of the fiber optic splice closure has always been a big problem, and the appropriate choice is made based on the dielectric properties and the degree of plasticity of the material itself. Therefore, the structure, material, and surface condition of the insulation also have a great influence on the withstand voltage strength performance of the fiber optic splice closure.
Reasonable insulation material is the fundamental guarantee for withstand high voltage DC breakdown. Therefore, the structure, material, and surface condition of the insulation also have a great influence on the withstand voltage strength performance of the fiber optic splice closure.
In order to improve the withstand voltage performance of the fiber optic splice closure, better insulating materials must be used to increase the surface finish and reduce the curvature between the insulator and the pole and pole and between the pole and the ground. With other parameters being the same, this situation can be increased by at least 100%.
The fiber closure is an indispensable and important part of the optical cable communication line. The main function is to realize the connection of the optical fiber cable, and at the same time, 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 component of the fiber optic splice closure and the grounding device and the cable reinforcing core are ensured. Insulate from each other to avoid adverse effects from the environment on the cable splice closures.
Since the environment in which fiber optical are used is basically outdoor, their use environment may be buried, overhead, or pipeline. Therefore, higher requirements are placed on the design of the fixing and grounding devices of the fiber optic splice closure and the insulating materials used.
Greentel Fiber Optic Splice Closure includes a connector body, a front and rear dust cover, an extrusion sleeve, and the like. The front part uses a ceramic tube with a very light connection surface to ensure the contact of the optical fiber and improve the durability. An elastic sleeve at the rear prevents the fiber from being torn.
Fiber optic splice closures are widely used today. It is precisely because of the development of optical fiber communication technology and the coverage of the national network. The requirements for fiber optic splice closures are also gradually increasing. There are also requirements on the length of the reinforcing elements for fiber optic splice closures, and the length of the reinforcing parts is required. Suitably, if the fiber optic splice closure reinforcement is pressed on the core bundle tube, the core bundle tube will be deformed by force and cause excessive loss, and the optical fiber in the core bundle tube will also be fractured due to long-term stress, leaving the project with Hidden danger.
The fixing of the optical cable must ensure that the position of the optical fiber in the fiber optic splice closure does not loosen, thereby avoiding the increase of optical fiber loss or the problem of fiber breakage due to the displacement of the optical cable. The fixing of the optical cable is divided into fixing of the reinforcing member and fixing of the rest of the optical cable.
The reinforcement must be fixed in its length. It is too long to fit in the fiber optic splice closure; it is too short to fix the cable. Generally, when cutting reinforcements, the distance between the clamping plate of the fixed cable and the screws of the fixed reinforcement should be equal to the length of stay. The rest of the fiber optic cable is fixed after the reinforcements are fastened, tighten the clamping plate with screws, and tightly fix it on the fiber optic cable inlet of the joint box.
