2、 Structural features:

1. The instrument insulation box body is made of a shell (made of composite epoxy resin) made of fiberglass or steel plate through special processes;

2. The box body is divided into an upper box body and a lower box body (with a sloping matching surface, and the upper and lower ends of the matching surface are arc-shaped). The upper and lower boxes are connected by stainless steel hinges, sealed with rubber strips, and the lower end is equipped with stainless steel hooks for compression. The front door is equipped with an observation window and a tilted rainproof top cover. The splash proof structure is used between the door and the box, which can prevent rain and dust and is suitable for indoor and outdoor installation;

3. The upper box can be opened up 90 degrees, and there is an opening support inside the box. Tightening the butterfly nut can fix the opening position, making it convenient to install and debug the instrument inside the box;

4. The bottom of the box is equipped with an instrument bracket that can move back and forth, left and right on the slide rail, making it convenient to adjust the installation position of the instrument and providing a comfortable working environment for engineering and technical personnel;

5. There is a disassembled piping board on the back of the box for installing various pipelines. Use a certain number of plastic seals at the bottom of the box to seal cable joints.
