Fiber Optic Splice Closure and optical fiber splice closures, also called barrels, are suitable for straight through and branch connections of various structured optical cable overheads, pipelines, direct embedding and other laying methods. In an optical communication network, the length of the optical cable is limited and the optical cable needs to branch on the transmission path, so that an optical cable connector is generated and the optical fiber splice closure is an optical cable that provides conditions for connection and branching Protect the connector and protect the connector.

At present, the application of optical fiber splice closure is very wide, but the insulation problem of optical fiber splice closure is always a big problem, and the dielectric properties and plasticity of the material itself are combined to make an appropriate choice. Therefore, the structure and material of the insulator and the state of the surface also have a great influence on the withstand voltage strength performance of the optical fiber splice closure.

If you want to improve the withstanding voltage performance of the optical fiber splice closure, use a better insulating material such as Teflon to increase the surface finish and increase the curvature between the insulator and the poles and poles and between the poles and the ground It is necessary to make small. Insulation gaskets conventionally used in optical fiber splice closures generally consist of two upper spacers and a lower spacer. The upper gasket is a concave gasket and the lower gasket is a convex gasket. Since the fixing bolt is connected to the reinforcing core of the communication cable, insulation is formed between the metal member of the optical fiber connecting plug and the cable reinforcing core (fixing bolt) by combining the upper and lower insulating spacers. In the compressive strength test, a DC voltage of 15 kV is applied between the fixing bolt and the metal member. Most of the materials used for insulating gaskets are polymeric polymers. The main feature of this method is to improve the combination of the upper gasket and the lower gasket.
