Dawnergy's direct burial type fiber optic Cross-connect Cabinet (OCC) is suitable for installation in the underground communication manhole environment, it is a high-performance IP68 waterproof, anti-condensation, moisture-proof, anti-corrosion buried underground can be used in a new OCC product, successfully solve the underground manhole waterproof, anti-condensation and other problems.

Features

The shell material is made of high-quality 304 stainless steel plate material, which has strong anti-corrosion performance and can be used in harsh environment for a long time.
The sealing of the cabinet is different from the original seal strip extrusion waterproof, the forced extrusion of passive waterproof concept into active waterproof, the use of air pressure high-performance waterproof principle structure, the installation of waterproof and pressurized air pressure sealing cover device referred to as "air pressure cover", the waterproof performance of this structure IP68.
The door is equipped with a waterproof vent, which can internal and external air circulation, so that the internal air and external air of the cabinet can be circulated to solve the condensation problem.
The cable inlet and outlet holes are sealed with metal double-locking 304 stainless steel gran head device, which has the waterproof function of double-sealed cable and the tensile performance of cable, and the waterproof grade is IP68.
The locking between the cabinet shell and the "air pressure cover" is provided with a (gravity self-locking) structure, which has a reliable closing locking function.
