Fabricating signal cable S03-74
1. Remove the anti-corrosive sheath by 500
mm. Remove the armor and vinyl sheath
leaving 50 mm each approximately.
2. Fold back the armor and trim to suitable
length. Then, slide the washer, rubber gas-
ket, washer and clamping ring onto the
cable in that order.
3. Unravel the outer shield to expose the cores
in the outer layer. Then, unravel the inner
shield to expose the cores in the inner layer.
Label all inner cores for later identification.
4. Attach EMI cores to all inner cores and
outer cores, and tie them with cable ties,
etc..
Note: There are two types of EMI core, thick
and thin.
5. Trim each core (except coaxial core) con-
sidering its location on the terminal board.
6. Trim the inner and outer shields leaving 50
cm each. Twist shields together and attach
crimp-on lug FV5.5-4 (blue, ø4).
7. Remove insulation of each core by 6 mm
approximately. Attach crimp-on lug
FV1.25-M3 (red, ø3) to each core.
8. Fabricate the coaxial cable. Make the length
10 mm longer than the shield to prevent
wire strain. Attach crimp-on lug FVD1.25-3
(red, ø3) to coaxial cable.
