Pre-construction inspection
The load tension of the steel belt clamp and wedge clamp must reach 6kN and 3kN respectively, and there must be no deformation or damage.
The location of the fixed point needs to be planned in advance in combination with factors such as the span and sag to ensure smooth cable laying.
Laying requirements
The bending radius of the optical cable should not be less than 30 times (static) and 20 times (dynamic) of the outer diameter to avoid excessive bending and structural damage.
Special tools (such as a pay-off rack) are required for the installation of the suspension wire to avoid twisting or back buckling of the optical cable. After laying, the cable needs to be stored in an "8" shape.
Fixed operation
After the pre-wiring is completed, install a wedge clamp at each fixed point, tighten the clamp and adjust the sag after the suspension wire is placed in the wedge groove.
When cutting the suspension wire, use a utility knife to separate the sling and the suspension wire at 15~2 0cm from the cable section to prevent damage to the cable structure.
