I believe that many people have a certain understanding of the fiber optic splice closure, because its application range is relatively wide, but the insulation problem of the fiber optic splice closure has been plaguing everyone, then how can we get rid of or damage the problem to The smallest?
Regarding the insulation problem of the fiber optic splice closure, we can make a suitable choice by combining the dielectric properties and plasticity of the material itself. Therefore, the structure and material of the insulation and the surface condition have a great influence on the withstand voltage strength performance of the fiber optic splice closure.
Insulation adjustment strategy of fiber optic splice closure! If we want to improve the withstand voltage performance of the fiber optic splice closure, then we must use a better insulating material such as Teflon to increase the surface finish, reduce the insulator and between the pole and the pole and between the pole and the ground. Curvature. In general, the insulating gasket used in the fiber joint box generally consists of two upper and lower gaskets.
The upper gasket is a recessed gasket and the lower gasket is a convex gasket. Since the fixing bolt is connected to the reinforcing core of the optical fiber, the upper and lower insulating spacers are combined to form an insulation between the metal member of the fiber optic splice closure and the optical fiber reinforcing core (ie, the fixing bolt).
In the compressive strength test, a DC voltage of 15 kV will be applied between the fixing bolt and the metal member. Most of the materials used for insulating gaskets are high molecular polymers. The main feature of this method is to improve the combination of the upper gasket and the lower gasket. In this way, we can effectively adjust the insulation of the fiber optic splice closure.
