Product Description

Product Introduction

Product Features

The box body can be opened before or after the door, the box has sufficient cloth fiber, fiber storage space, there are enough winding reel, hanging line hook, convenient for users to operate.
The box body is made of high-quality stainless steel plate, and after electroplating and plastic spraying treatment, it not only has good corrosion resistance and aging resistance, but also has good sealing performance of the box body, which can withstand severe climate changes and harsh working environment, and the protection level reaches IP65 requirements in GB4208.
The junction box is divided into upper, middle and lower layers. The upper layer is the top of the box, which can be naturally ventilated. Through the adjustment of the natural wind on the top of the box and the double-layer insulation on the four sides of the box, the temperature change range in the box is smaller than the outdoor temperature change range, so as to improve the reliability of the junction box. The junction box has more tenacious field resistance and can withstand severe climate changes and harsh working environment.
The extra weld disk can be used as a direct melt.
The fiber optic cable reinforcing core can also be used in the form of fiber optic cable fixing cover according to the needs of users, which is suitable for ordinary and ribbon fiber optic cables.
USES the flying saucer type direct melting plate, small volume, direct melting capacity.
Grounding mode: the box has two floors, one of which is protective ground, and the fiber optic cable reinforcing core is connected with the protective ground. The other layer is the rack ground, which is not connected to each other and leads to the ground of the machine room through their respective grounding wires.
