More models are not listed, and can be made according to the design.
In order to facilitate wiring in special occasions, our company has specially developed some special types of junction boxes and junction cabinet. The number, direction and size of inlets, outlets can be designed according to customer requirements. According to the capacity of the design load, the terminals in the junction box cavity can be arbitrarily changed to meet demand, the maximum terminal capacity can reach 200A.
Before installation, please carefully check the connection box (such as damage, deformation, looseness, etc.), otherwise it is not allowed to install and replace it in time. When connecting the internal wiring, the connecting screw should be tightened. It is strictly forbidden to entangle the cores in the connection box to ensure sufficient electrical clearance. The ground line shall be connected to the connection box or cabinet in explosion-proof area.
The size of the sealing rubber ring should be matched with the size of the power cable and electric heating cable during installation, and cannot be exchanged at will so as to ensure the explosion-proof performance.
In the case of explosion-proof, the inlet shall be equipped with an explosion-proof clamping granule to ensure explosion-proof performance
Check whether the sealing rubber ring on the cover of the explosion-proof power connection box (box) is complete after wiring to ensure the protection performance.
