1.  Check the labels at both ends (0.3 m) of the primary feeder 
to ensure that it is the right cable.  
2.  Wrap the main feeder connector with a piece of flax or an 
antistatic plastic bag filled with foam, and then bind it tightly 
with cable ties. 
3.  Knot the hoisting rope at the place about 0.4 m away from 
the connector and knot the rope again at the place about 3.4 
m away from the connector to allow cooperation between 
personnel on the tower and ground and  protect the feeder 
and its connector from being damaged by hitting the tower. 
4.  After the feeder has been hoisted to the tower top, fasten it 
tightly at multiple points to prevent it from sliding from the 
tower.

Main Feeder Laying and Fixing 
Laying requirements 
„ 
The main feeder  must be laid in good order, without 
crossing. 
„ 
Learn its route before connecting the main feeder. You 
are recommended to mark the actual route on the 
drawing to avoid reworks  due to crossings of the main 
feeder.  
„ 
The minimum bending radius of the main feeder must be 
no less than 20 times of the radius of the main feeder. 
The radius of a single bend must not be less than 90 mm. 
The minimum bending radius of repeated bends must be 
200 mm. 
„ 
Spacing of the triple feeder clip: 1.65 m for the maximum.  
Main feeder connecting steps: 
1.  Triple feeder clips  must  be installed in advance along the 
tower or cable rack at spacing of about 1.5 m. The spacing 
can be lengthened or shortened depending on the actual 
situation, but must not exceed 1.65 m. The spacing between 
the triple feeder clips must be as even as possible and in the 
same direction. If two rows of feeder clips are installed on 
one cabling ladder, keep them in parallel and in good order.
