GP31-2-a22 outdoor fiber optic cable transfer box
The box body can be opened front or back. There is sufficient space for cloth fiber and fiber storage, sufficient winding reel and hook for user operation. The box body is made of high-quality stainless steel plate, and is electroplated and sprayed. It not only has good corrosion resistance and aging resistance, but also has good sealing performance. It can withstand severe climate changes and harsh working environments. The protection level Reach the IP65 level requirement in GB4208.

The transfer box is divided into upper, middle and lower layers. The upper layer is the top of the box, which can be naturally ventilated. After the natural wind adjustment of the top of the box and the double-layer heat preservation on the four sides of the box, the temperature change range in the box is smaller than the outdoor temperature change range. Improve the reliability of the transfer box, the transfer box is more tenacious anti-field performance, can withstand severe climate changes and harsh working environment.
The surplus splice tray can be used for direct welding.
According to the needs of users, the fiber optic cable reinforcement core can also be in the form of a fixed cover for the fiber optic cable, which is suitable for ordinary and ribbon fiber optic cables.
Using flying saucer type direct melting plate, small volume, large direct melting capacity.
Grounding method: The box body has two layers of ground, the first layer is a protective ground, and the fiber optic cable reinforcement core is connected to the protective ground. The other layer is the rack ground. The grounds of the two layers are not connected to each other, and they lead to the ground of the machine room through their respective ground wires.
