In the world of electrical installations, the way rigid fittings are attached to conduits is of utmost importance. There are several common methods that ensure a secure and proper connection.
One of the methods is through threadedhubs. The threading allows for a tight and firm connection. The threaded hubs on conduitscan be used to hold the wires firmly in junction boxes and terminal boxes, ensuring the stability and safety of wire connections. The conduits, withthreaded hubs at their ends, are installed to provide a physical barrier andprotect the wires from external damage. They provide a threaded hole for screwsor bolts, ensuring a tight and stable connection between different componentsof an electrical device or system.
Another approach is using set screws. Set-screws are used to secure fittings such as elbows, tees, couplings, and so on. They are tightened onto the conduit surface, creating a clamping force that keeps the fitting from moving. This method isrelatively simple and can be a cost-effective solution in some cases. The proper selection and installation of set-screws are crucial to ensure the integrity and safety of the assembled components. It is important to considerfactors such as the material of the screw, the size and shape of the head, andthe torque requirements for installation.
The compression type nuts with gland rings also plays a significant role in attaching rigid fittings to conduits. In theelectrical industry, compression nuts are usually used together with glandrings, mainly for cable sealing and fixation. When the compression nut istightened, it will apply uniform pressure to the gland ring, causing the ringto deform and fill the gaps between the nut, the cable and the equipment interface, thus forming a reliable sealing environment. This combination has a wide range of applications in various electrical equipment, including junctionboxes, control cabinets, distribution boxes, etc.
To sum up, whether it's through threadedhubs, set screws, or compression type nuts with gland rings, each method has its own advantages and is chosen based on the specific requirements of theproject. These attachment methods contribute to the overall integrity and functionality of the conduit system, ensuring that it can perform its intendedtasks effectively.
