Classification:

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.

Prefabricated customized boxes are used, which are divided into low-voltage warehouse, medium-voltage warehouse, machine warehouse and spare parts warehouse according to different functions, including all power distribution units such as medium and low-voltage power distribution cabinets, transformers and various monitoring components in Shengdao. Decoration, equipment installation, wiring, system integration and debugging are completed in the factory. At present, there are mainly two types of container-type square warehouse and skid-type square warehouse.

Product Description

Product Introduction

Product Features

The junction box has the functions of wiring, welding, fiber storage and fiber adjustment, has strong resistance to field environment, and can withstand severe climate changes and harsh working environment. The box has good sealing performance and the protection level reaches IP65 requirements.
The box body is made of high-quality stainless steel plate, which not only has good corrosion resistance and aging resistance, but also has beautiful appearance.
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.
Modular design, reasonable layout, multi-function and high density.
It adopts anti-theft door lock shape, which is safe and reliable, and has good anti-damage function. The box has a flexible incoming and outgoing optical cable structure and a flexible internal connection structure.
USES the flying saucer type direct melting plate, small volume, direct melting capacity.
Adopt six adapter card structure; FC type or SC type adapter can be used according to user needs.
The box is compact, lightweight and easy to install.
Can use FC or SC type adapter, adapter 40 ° oblique angle, can avoid the arc of the human eye.
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.
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.
There is a special fiber optic cable straight-through fusion zone in the box, and the two ends of the fiber optic cable are connected in the straight-through fusion zone.
The bottom of the box is high and the space is large, so that when the optical cable is introduced, it has a larger radius of curvature, and the installation and operation are convenient.
The radius of curvature of the optical fiber ≥ 30mm (internal control 40mm).
The rack has a good grounding system.
The plastic parts in the machine are made of flame retardant materials.
