The most important Construction design

In order to properly design the structure of the ADSS cable, many aspects must be considered, including mechanical strength, conductor sag, wind speed b ice thickness c temperature d topography, Span, and Voltage. 

Usually, when you are in production, you need to consider the following questions.

Jacket Type: AT/PE

PE sheath: ordinary polyethylene sheath. For power lines below 110KV and &#;12KV electric field strength. The cable should be suspended where the electric field strength is small.

AT sheath: anti-tracking sheath. For power lines above 110KV, &#;20KV electric field strength. The cable should be suspended where the electric field strength is small.

Out Cable Dia.: Single Jacket 8mm-12mm; Double jacket 12.5mm-18mm

Fiber Count: 4-144Fibers

Aramid Yarn Details: Something like (20*K49 D). This main calculation of tensile strength.

According to the stress formula, S=Nmax/E*ε,

E (Tensile modulus)=112.4 GPa&#;K49 Dinner&#;

ε=0.8%

Usually designed strain<1%&#;Stranded Tube&#;UTS;

&#;0.8%&#; evaluation

Nmax=W*(L2/8f+f);

L=span(m);usually 100m,150m,200m,300m,500m,600m;

f=Cable sag; usually 12m or 16m.

Nmax=W*(L2/8f+f)=0.7*&#;500*500/8*12+12&#;=1.83KN

S=Nmax/E*ε=1.83/114*0.008=2 mm&#;2;

Saramid(K49 D)=*10-4/1.45=0.mm&#;2;

N numbers aramid yarn=S/s=2/0.=9.2

General aramid fiber hinge pitch is 550mm-650mm,angle=10-12°

W=Maximum load (kg/m)=W1+W2+W3=0.2+0+0.5=0.7kg/m

W1=0.15kg/m(This is the weight of ADSS cable)

W2=ρ*[(D+2d)&#;2;-D&#;2;]*0./(kg/m) (This is the weight of ICE)

ρ=0.9g/cm&#;3;, the density of ice.

D=Diameter of ADSS. Usually 8mm-18mm

d=Ice cover thickness;No ice=0mm,Light ice=5mm,10mm;Heavy ice=15mm,20mm,30mm;

Let's say the ice is thick is 0mm, W2=0

W3=Wx=α*Wp*D*L=α*&#;V&#;2;/&#;*(D+2d)*L/9.8 (kg/m)

Let's say the wind speed is 25m/s, α=0.85; D=15mm;W3=0.5kg/m

Wp=V&#;2;/ &#;Standard partial pressure formula, V means wind speed&#;

α= 1.0(v&#;20m/s);0.85(20-29m/s);0.75(30-34m/s);0.7(&#;35m/s) ;

α means Coefficient of the unevenness of wind pressure.
