Structure Overview:
The outer shell of the switchgear is made of 2.5mm thick cold-rolled steel plate, which can withstand the impact strength and strength test specified by national standards and the technical conditions of this product. The cable is led into the cable trench and sealed with explosion-proof adhesive after installation. The switchgear is fixed. The unused inlet during installation is blocked with explosion-proof adhesive.
Usage conditions and environment:
Altitude: 1000m;
Environmental temperature: -20¡æ¡«+40¡æ;
Relative humidity: 95%;
In a gas or steam environment that does not damage insulation;
Before installation, check whether the nameplate, specifications, and explosion-proof type meet the requirements.
It is strictly prohibited to open the cover with electricity during use and maintenance.
The cable is led into the cable trench and sealed with explosion-proof adhesive after installation. The switchgear is fixed
The switchgear is equipped with internal and external grounding terminals, which must be reliably grounded during installation
When connecting wires, multiple strands of wire must be crimped with suitable terminal heads and safely pressed onto the terminal blocks. There should be no scattered wire heads outside to avoid discharge.
