Byose-dielectric yifashisha (ADSS) umugozi ni ubwoko bwa fibre optique ya fibre optique ifite imbaraga zihagije zo kwibeshaho hagati yimiterere idakoresheje ibyuma byayobora.Ikoreshwa namasosiyete akoresha amashanyarazi nkuburyo bwitumanaho, yashyizwe kumurongo usanzwe wohereza hejuru kandi akenshi ugabana ibyubaka nkibikoresho byamashanyarazi.
Mwisi yisi yitumanaho, ikoreshwa ryaByose-Dielectric Kwishyigikira (ADSS) insingayarushijeho kumenyekana bitewe nuburyo bwinshi kandi burambye.Ariko, gushushanya no gutanga umugozi wa ADSS iburyo birashobora kuba inzira igoye kandi itoroshye.
Igishushanyo cyingenzi cyubwubatsi
Kugirango dushushanye neza imiterere yumugozi wa ADSS, hagomba gutekerezwa ibintu byinshi. Harimo imbaraga zubukanishi, umuyoboro wa sag, Umuvuduko wumuyaga b urubura rwubushyuhe c ubushyuhe d topografiya, Span, Umuvuduko.
Mubisanzwe, mugihe uri mubikorwa, ugomba gusuzuma ibibazo bikurikira.
Ubwoko bw'ikoti: AT / PE
PE sheath: icyatsi gisanzwe cya polyethylene.Kumurongo w'amashanyarazi uri munsi ya 110KV, na ≤12KV imbaraga z'umuriro w'amashanyarazi.Umugozi ugomba guhagarikwa ahantu ingufu z'amashanyarazi ari nto.
KURI sheath: anti-track sheath.Kumurongo w'amashanyarazi hejuru ya 110KV, ≤20KV imbaraga z'umuriro w'amashanyarazi.Umugozi ugomba guhagarikwa ahantu ingufu z'amashanyarazi ari nto.

Aramid Yarn Ibisobanuro: Ikintu nka (20 * K49 3000D) Iyi mibare nyamukuru yimbaraga zingutu.
Ukurikije formulaire yo guhangayika, S = Nmax / E * ε,
E (Modulus ya Tensile) = 112.4 GPa （K49 1140 Ifunguro rya nimugoroba）
ε = 0.8%
Mubisanzwe byashushanyije <1% （Guhagarara Tube） UTS;

Nmax = W * (L2 / 8f + f);
L = span (m); mubisanzwe 100m, 150m, 200m, 300m, 500m, 600m;
f = Umugozi sag ； mubisanzwe 12m cyangwa 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 mm²
Saramid (K49 2840D) = 3160 * 10-4 / 1.45 = 0.2179mm²
N imibare aramid yarn = S / s = 2 / 0.2179 = 9.2
Rusange aramid fibre hinge ikibanza ni 550mm-650mm, inguni = 10-12 °
W = Umutwaro ntarengwa (kg / m) = W1 + W2 + W3 = 0.2 + 0 + 0.5 = 0.7kg / m
W1 = 0.15kg / m (Ubu ni uburemere bwa kabili ya ADSS)
W2 = ρ * [(D + 2d) ²-D²] * 0.7854 / 1000 (kg / m) (Ubu ni uburemere bwa ICE)
ρ = 0,9g / cm³, ubwinshi bwa bara.
D = Diameter ya ADSS.Mubisanzwe 8mm-18mm
d = Uburebure bwa barafu; Nta rubura = 0mm, Urubura rworoshye = 5mm, 10mm; urubura rukomeye = 15mm, 20mm, 30mm;
Reka tuvuge ko urubura ari rwinshi ni 0mm, W2 = 0
W3 = Wx = α * Wp * D * L = α * （V² / 1600） * (D + 2d) * L / 9.8 (kg / m)
Reka tuvuge ko umuvuduko wumuyaga ari 25m / s, α = 0,85;D = 15mm; W3 = 0.5kg / m
Wp = V² / 1600 formula Inzira isanzwe yumuvuduko ， V bisobanura umuvuduko wumuyaga）
α = 1.0 (v ＜ 20m / s); 0,85 (20-29m / s); 0,75 (30-34m / s); 0.7 (＞ 35m / s);
α bisobanura Coefficient yuburinganire bwumuyaga.

RTS: Ikigereranyo cyimbaraga
Yerekeza ku gaciro kabaruwe k'imbaraga z'igice cyo gutwara (cyane cyane kubara fibre izunguruka).
UTS: Ultimate Tensile Imbaraga UES> 60% RTS
Mubuzima bwiza bwumugozi, birashoboka kurenza umutwaro wogushushanya mugihe umugozi nuburemere ntarengwa.Bivuze ko umugozi ushobora kuremerwa mugihe gito
MAT: Max yemerewe guhagarika akazi 40% RTS
MAT ni ishingiro ryingenzi rya sag - impagarara - kubara umwanya, kandi nubuhamya bwingenzi buranga imiterere-karemano iranga insinga ya optique ya ADSS. Yerekeza ku gishushanyo mbonera cyimiterere yubumenyi bw'ikirere ukurikije kubara k'umutwaro wose, umurongo wa kabili.
Muri iyi mpagarara, fibre fibre ntigomba kurenga 0,05% (laminated) kandi ntigomba kurenga 0.1% (umuyoboro wo hagati) utabanje kwiyongera.
EDS: Buri munsi Imbaraga （16 ~ 25）% RTS
Impuzandengo yumwaka yumwaka rimwe na rimwe yitwa impuzandengo ya burimunsi, yerekeza kumuyaga kandi nta rubura hamwe nubushyuhe bwikigereranyo cyumwaka, kubara mubyerekeranye no kubara insinga zumutwaro, birashobora gufatwa nka ADSS mubikorwa byigihe kirekire byimpuzandengo yikigereranyo (igomba) imbaraga.
EDS muri rusange (16 ~ 25)% RTS.
Munsi yiyi mpagarara, fibre ntigomba kugira imbaraga, ntayindi attenuation, ni ukuvuga, ihamye cyane.
EDS nayo ni umunaniro wo gusaza wibikoresho bya fibre optique, ukurikije igishushanyo mbonera cyo kurwanya fibre optique.
Muri make, gushushanya no gutanga umugozi ukwiye wa ADSS bisaba kumva neza ibisabwa byumushinga, guhitamo ibikoresho byujuje ubuziranenge, no gushyira mu bikorwa ingamba zikomeye zo kugenzura ubuziranenge.Hamwe nibitekerezo, abatanga itumanaho barashobora gukoresha byimazeyo insinga za ADSS zujuje ibyifuzo byumunsi wo guhuza.
