How To Install A Strain Relief Clamp
Guide to cable strain relief and protection

How to strain relief wires? Wire strain relief methods explained:
Whenever yous're working with any type of conductor or cable, protecting them from impairment is essential. When working with them inside or outside of an enclosure, this entails keeping them from undue strain, whether from an excessive curve radius, pulling or tugging, or from the cable sheathing itself.
There are a variety of cablevision and wire strain relief methods available. Of course, when using voltage carrying conductors, protecting the cable likewise protects personnel and equipment from harmful exposure to electrical electric current. Let'due south start our guide there.
Electrical strain relief fittings and bushings
As mentioned, protecting electric conductors from damage is essential from both an equipment- and human-protection standpoint. Frequently, some type of flexible metal conduit – sometimes with the wiring already installed – is used instead of a rigid type conduit.
Then there are electric cords such as SEOW (S=Service, Due east= Elastomer, O= Oil-resistant insulation and West=Atmospheric condition and water resistance). For these jacketed cords, in that location are diverse types of wire strain relief methods. For case, string grips, sometimes called cable glands, are a type of electrical cord strain relief that provides 2 types of protection for flexible cords. Not only does it prevent the cable insulation from being penetrated by the sharp edges of the enclosure or electrical box, but from beingness pulled out of the box as well.
Depending on the environment, y'all can use either a metallic blend or plastic cable strain relief grip. These electrical cable strain relief grips come up in either a straight or angled configuration.
Some cable strain reliefs don't provide protection from pulling strength. Instead, they are used to allow cables to pass through holes in furniture, enclosures, and other surfaces without causing harm to either the string or the device. For example, a universal bushing can be inserted into a hole drilled into a desktop and several cables of various sizes can be run through the bushing.
Some have a carve up design, every bit seen below, to conform to the hole size, while others are of a fixed bore. A carpenter or electrician will know how to install strain relief bushing types like this. Special cutting tools, such as a pigsty saw, are needed to install these bushing and ensure a snug, clean fit.
Compression strain relief bushing types
While often used for small-scale or apartment electric cords, there are compression plastic strain relief bushing and grommet styles that are unproblematic to install. In electronic equipment, they absorb button, pull, and twisting forces that the cord may exist subjected to during utilize.
They snap into either a round or anti-rotation hole and when inserted, they shrink against the cord or cable. To remove them for cord replacement, you can purchase a set of strain relief bushing pliers that go far easier. Notwithstanding, slip fit or aqueduct locking pliers are oftentimes how many technicians remove strain relief bushing and cablevision installations.
Plainly, there are many electric cord strain relief bushing and grommet options from which to cull. Consider the surroundings, purpose, and other special situations to ensure making the correct choice.
Cobweb and low-voltage wire strain relief methods
When installing cobweb optic cable and other low voltage cables like ethernet, you tin use some of the same electric strain relief bushing and grommet sets as with electrical cables.
However, at that place are some specialized cable strain relief bushing products fabricated specifically for fiber and related cabling. Some products aren't bushings per se, but guides to route the fiber and cabling smoothing in an enclosure. Because of the rather frail nature of these cabling systems, yous need to foreclose kinking or an excessively small radius bend when installed.
Hither are a few other options:
As with electrical cabling, take all environmental and occupational weather into account when choosing the products you demand for fiber installation.
