A chart for sizing the correct gauge cable is towards the bottom of the page, as well as guidelines for installation.
To order an air cooled cable, you need to know several specifications for that cable. The following will walk you through this process.
1. Select Styles of Terminal
|End Styles||End Combinations|
|2. Taking Measurements:
Length of the Cable = L
The terminal thickness is dependent on the terminal face width, and the gauge of the cable, as outlined in the table below.
|MCM||1.250" Wide||1.375" Wide||1.500" Wide|
3. More Cable Options:
Cables with isolated, individually wrapped conductors increase cable life by preventing common failure points:
Increased strand life at the cable terminal is the advantage of a stabilizing collar. It slightly increases the minimum flex radius for the jumper, reducing over flexing.
36 AWG copper rope stranding and an extra flexible protective cover are used to create an extra flexible jumper. The result is a jumper that is over twice that of a regular jumper. This makes it ideal for robotic applications and where limited space makes standard cables a hard fit.
The DJ-XF is available in 750, 1000, and 1200 MCM. Other options include a perforated cover or a special Hypalon high temperature cover, able to withstand 300°F to -30°F.
How to install air cooled cables
Bend radii should not be sharp, and should be distributed throughout as much of the jumper as possible, in order to distribute the frictional wear over the greatest possible area. See the below charts for suggested minimum bend radii.
Lay one side of a straight edge across the graph at the six cycles of current "one time" point (the left hand vertical scale of the conversion factor chart).
Now proceed to the Air Cooled Jumper Selection Chart to read complete the selection.
Line up your straight edge on the 3200 continuous duty amp mark, and find the intersection with your desired length line (from below).
Any cable whose line is above this point may be safely used, since the load it would carry will be within its thermal capacity. In this example a 1200 MCM cable can be used and stay within design tolerances.
