1. The outer shell of the product is an increased-energy outer casing. It adopts a die-casting process of cast aluminum alloy. The surface is smooth, the appearance is beautiful, the internal structure is high density and the impact resistance is strong.

2. After the surface of the outer casing is processed by industrial robots to remove burrs and high-speed shot blasting, the advanced automatic high-pressure electrostatic spray and heat-curing line technology is adopted, and the plastic layer formed on the surface of the shell has strong adhesion and good anti-corrosion ability.

3. The main cavity is an increased safety type housing with various explosion-proof Ex components such as explosion-proof indicator lights, buttons, voltage, ammeter and transfer switch.

4. The transfer switch function can be selected according to user requirements and the performance is reliable. The switch is connected to the external handle through the rotating shaft, and the sleeve is permanently fixed on the cover, which is firm and reliable.

5. The sealing strip adopts two-component polyurethane primary casting foaming process with high protection performance.

6. Outdoor products can be equipped with rain cover according to user requirements.

7. The installation method is generally column type, and can also be made into hanging type or bridge type, or can be specially made according to user requirements. Hanging and bridge mounting can be made into the upper or lower line.

8. All exposed fasteners are made of stainless steel.

9. Steel pipes and cable wiring are available.
