CABLE TRAY FABRICATION TECHNIQUES:
THEORIES FOR BEGINNERS 👇
Measurements:
1. Using the size of the cable tray, and multiply by (0.8).
e.g (150 size of cable tray is = 15 size. )
( 200 = 20) (100 =10) (75 = 7.5)
(50 = 5 )
Examples: 200 size >> calculate 0.8 x 20 =16
Now, you have to use 16cm for the measurement. that's 8cm by 8cm.
> for 150 Sizes >> calculate 0.8 x 15 = 12
Now , you have to use 12cm for the measurement. that's 6cm by 6cm.
>for 100 Sizes >> calculate 0.8 x 10 = 8
Now , you can use 8cm for the measurement. That's 4cm by 4cm
> for 75 sizes >> 0.8 x 7.5 = 6
Now , you can use 6cm. that's 3cm by 3cm
> for 50 sizes >>0.8 x 5 = 4
Now, use 4cm. That's 2cm by 2cm
CREATING A 90 DEGREE TURNING/ ANGLE 90 AS YOU MAY CALL IT:
The 90 degree can be created using the earlier stated measurements, based on the Sizes of the cable tray. e.g 200 size cable tray. Use 16cm, that's 8cm by 8cm to fabricate in two different points, depending on the length of twist.
e.g one point using 16cm, and another point using same 16cm = 90 degree.
DIFFERENT KINDS OF CABLE TRAY FABRICATION TWIST:
1. Backwards and upwards unilateral twist: this is done, when you create a cable tray twist, by forming a bend downward in one joint and upward bend in another joint depending on your length of measurement or where the twist are needed.
2. Sideways unilateral twist: the same thing applicable here as the backwards & upwards unilateral twist. But with different style and pertern applied.
3. backwards and Sideways twist:
4. Upwards and sideways twist:
