Overview

The GJS05-W series optical cable joint box products belong to an openable mechanical pressure-sealed joint system, widely used for direct burial, pipeline, and overhead laying methods for direct and branch connections.

Features

The box body is made of high-quality engineering plastic (PC), and all external fasteners and components are made of high-quality stainless steel materials.
The product uses secondary cable pressing technology to ensure that the optical fibers inside the box have no additional attenuation.
The product has the function of disconnecting the electrical connection of the incoming and outgoing optical cables.
The product has multiple reuse and expansion capabilities.
A valve can be installed on the shell for easy inflation and pressure measurement during sealing inspection.
A grounding lead device can also be installed on the shell.

Main Technical Indicators

- Tensile Seal: After sealing the box body and inflating it to 60kPa, it can withstand a tensile force of 1000N without leaking.
- Impact Seal: After sealing the box body and inflating it to 60kPa, it can withstand three impacts of 16Nm without cracks or leaks.
- Insulation Resistance: The insulation resistance between the metal components at both ends inside the box and between the metal components and the ground is not less than 20000MΩ.
- Dielectric Strength: The insulation between the metal components at both ends inside the box and between the metal components and the ground does not break down under 15kV DC for 1 minute, with no arcing phenomenon.
- Service Life: ≥25 years.
