If there is an aluminum laminate or a corrugated steel sheet in the, the cable peeling can be done as
follows:
•
Remove the cable jacket and other protective layers in several parts to approximately 50 mm
from the starting point of the peeling.
•
Remove the jacket from top of the aluminum laminate or steel sheet using pliers and hot air
blower.
•
To ensure electrical contact, remove the plastic film on top of the aluminum laminate or steel
sheet, e.g. with a steel brush or knife.
•
Bend the cable traction elements parallel to the side of the cable and approximately 30 mm
from the cable. Try to get the traction elements as straight and close as possible to each
other so that they can be inserted as easily as possible into the grounding connector.
•
Cut the traction elements to the same length as aluminum laminate or steel sheet.
The protection of fibers in CLT cables with SPA-U installation kit:
•
Insert the fastener of SPA-U installation kit to the base of the central tube.
•
Cut the central tube of the cable at approximately 30 mm from the edge of the aluminum
laminate or steel sheet and with a metal-free cable at approximately 30 mm from the cable
jacket. Cut the central tube, first making a transverse incision around the tube, and then
gently bending the tube on both sides until it breaks.
•
Pull the center tube off the fibers while holding the fibers at the cutting point.
•
Clean the fibers from gel.
•
Push the SPA-U installation kit divider over the center tube while controlling the fiber
bundles through the slots. Fasten the divider to the central tube with a previously threaded
fastener. If the attachment is not tight enough, use the fitting pieces supplied with the
installation kit.
•
Pull the fibers in bundles into the protective tubes of the installation kit using the pull spring
in the set. The minimum length of the installation kit is 110 cm.
•
Mark the ends of fiber tubes with numbers.

Placing the fibers on the splice tray
•
Remove the cover and the protective tape from it.
•
Measure the fiber lengths on the splice tray. The fibers needed for Naficon's universal splice
trays are about 120cm.
