Enclosure Cable Entry

Cable entry is a crucial aspect of any cable management setup, especially in scenarios involving electrical cabinets, control cabinets, or any other types of enclosures that house electrical equipment. The right cable entry system can make a significant difference in how well cables are organized, protected, and accessed.
For example, modular cable entry systems often feature different frame sizes and are made of durable materials like stainless steel to offer a strong connection between the cable and the enclosure. They are generally equipped with round cable entry plates, or sometimes a cable entry frame, to allow cables of different diameters to pass through. Cable glands are another commonly used component in cable entry systems, providing strain relief and ensuring a tight seal around each cable.
For cases where you have pre-assembled or pre-terminated cables, specialized cable entry plates or frames are available that allow these types of cables to be installed without requiring the connectors to be removed. This is a significant advantage, as it saves both time and space.

Similarly, non-terminated cables can also benefit from well-designed cable entry systems. Strain relief mechanisms can be integrated into the system to protect the integrity of the cables. For instance, thermoplastic elastomer components can offer a high degree of flexibility and durability, ensuring that cables remain secure and protected.
Easy assembly is another feature often sought in cable entry systems. The aim is to reduce the amount of time needed for the installation process, which can be especially valuable in industrial settings or other environments where downtime is costly. The right product range can offer options for easy assembly, ensuring that a single enclosure can handle multiple types of cables and wires through one opening.
Overall, the choice of cable entry systems and their accessories significantly influences how effectively cables are managed, how much space is used efficiently, and how well electrical components are protected. It's a key aspect to consider when planning and installing any cable management infrastructure.
FAQs
Does a control cabinet sometimes come with pre-assembled cables or integrated strain relief?
Yes, some control cabinets come with features like pre-assembled cables or integrated strain relief to make the installation process easier and more efficient. These features can be particularly useful in industrial settings where downtime for setup or maintenance can be costly.
Are a cable shield and a cable gland the same thing?
No, a cable shield and a cable gland are not the same thing; they serve different purposes in cable management and protection. A cable shield is typically a conductive layer that surrounds the conductive cores of a cable, while a cable gland is a mechanical device used to secure and seal a cable as it passes through an enclosure.
Control Panel Fabrication: Best Practices
Use a larger enclosure whenever possible.
This allows room in the panel design to properly space all of the hardware and to install larger wire ducting. Panels that have ample space tend be me more organized, while panels that have everything crammed into a small space tend to be more difficult to work in and are often less organized.
Tap holes instead of using self-tapping screws.
It is common for panel builders to use self-tapping screws to save time during the fabrication process. While it can save time, this type of fastener does not always provide the consistent, strong connection that may be needed for the mounted hardware. This is especially true when hardware may need to be removed at some point and then later reattached. Holes that have been tapped prior to hardware installation will offer a stronger, more consistent connection point that will last longer.
Ensure that wire ducting is large enough.
It is very easy to undersize wire ducting when designing a panel. It is important to always plan for wire ducting to have extra room available once all wires have been run through it, including field wires.
When in doubt, label it.
It is a very good practice to label wires in a control panel, but it is not always required to label the other types of hardware in the panel to meet code. It is important to understand that any operators that may access this panel at a later date may not understand what the hardware in the panel is intended for. To make the panel is as safe as possible, and to allow operators to function in the panel more efficiently, it is a good idea to label everything that may come into question.
