Issues related to the use of explosion-proof flexible hoses
Thread Content
Guys, how are the power supply lines connected to the explosion-proof motors on site? Is it the protection tube that leads to the explosion-proof flexible tube before reaching the motor? However, the wiring terminals of ordinary explosion-proof motors are not threaded; so how can they be connected to explosion-proof flexible hoses? Do any of you have good examples for learning*?
The wiring of explosion-proof motors must be threaded. Yours is not an explosion-proof motor.
The inlet ports of the wiring boxes for explosion-proof motors all have threads; if there are no threads, they can be sealed with explosion-proof putty
There are various ways to connect power to explosion-proof motors: flared ends, clamping types, and threaded connections. Generally, whatever type of connection fitting is used for explosion-proof fittings, that will be the same type of connection used for supplying power to the motor. If a flexible pipe connection is used, it must be specified in advance to the manufacturer, so that they will use motors equipped with threaded flanges.
