Ol 'Strain Triangle Yoke Plates' em ol i save yusim long ol 'overhead transmission lines', na ol i save yusim long bungim, tilim, na salim 'tension' namel long planti 'insulator strings' na 'conductors'. Long wok tru, 'yoke plate' i save sanap strong long 'conductor tension', 'wind-' induced vibration, 'icing loads', 'temperature stress', 'lightning strikes', na planti kain 'corrosion' i kam long win, 'salt spray', na 'industrial pollution'. Strong bilong en, strong bilong en long sait bilong masin, na strong bilong en long sakim bagarap i makim stret seif operesen level bilong olgeta transmisin lain. As tingting na samting ol i mas mekim pastaim long ol dispela samting em long makim ol samting bilong saiens long taim bilong wokim ol samting.
Seleksen bilong ol samting bilong wokim em i no long makim wanpela kain ain tasol, tasol em i wanpela gutpela disisen we i kamap long planti samting, olsem 'voltage rating', 'design tension', 'operating environment', 'procesing technology', ol samting bilong lukautim 'corrosion', 'cost control', na ol 'domestic' na 'international standards' na 'specifications'. Ol kemikel komposesen, ol samting bilong masin, ol samting bilong weldim, ol samting bilong wok long kol, ol samting bilong mekim wok long hat-dip galvanising, pasin bilong sakim korosen, na ol samting bilong les bilong dispela samting i save mekim stret long kwaliti bilong pinis prodak, sevis laip, na sefti mak bilong Strain Triangle Yoke Plate.
Taim yu makim ol samting bilong wokim Strain Triangle Yoke Plate, ol bikpela mak bilong pefomens we yu mas inapim em yu mas tingim long ol dispela samting:
Strong inap long: inkludim strong bilong 'yield' na 'tensile strength', na bai i no gat plastik i bruk o bruk aninit long bikpela disain lod;
Gutpela 'plasticity' na 'toughness': stopim 'brittle fracture' aninit long liklik tempereja, 'impact', na 'vibration';
Gutpela 'fatigue resistance': i no inap long win i seksek longpela taim na ol hevi i save senis senis, na i no inap long kamapim 'fatigue crack';
Gutpela wok: inkludim pasin bilong katim, sutim, bendim, weldim, stretim, hot-dip galvanising, na ol narapela samting;
Korosen resistens: inapim ol hot-dip galvanising rikwaemen, wantaim wankain 'zinc layer', strongpela adhesion, na nogat inkomplit galvanising, 'brittleness', o 'pitting';
Stebol kemikel komposesen: ol samting nogut olsem kabon, salfa, na fosforas i stap aninit long ol standet mak bilong mekim welding na galvanising i kamap gutpela.
Longpela taim ol i bin mekim wok long wokim ol 'transmission line fittings', ol i brukim ol samting bilong Strain Triangle Yoke Plate i go long 4-pela lain: 'carbon structural steel', 'low alloy high-strength structural steel', 'weather-resistant structural steel', na 'high alloy -strength structural steel.
Kabon straksel stiel em i nambawan samting nau we ol i save yusim na em i nambawan samting bilong wokim ol 'strain triangle yoke plates' long ol 'medium' na 'low voltage transmission lines' insait long kantri na long ol narapela kantri. Em i gat ol gutpela samting olsem em i no gat bikpela pe, em i gutpela long wokim long masin, em i gutpela long weldim, na em inap long stretim gut long 'galvanizing'. Kabon i stap insait long en i no bikpela tumas, planti taim em i liklik o wankain olsem 0.20%, na dispela i mekim na em i ken kamap strong, strong, na inap long weldim. Ol samting nogut olsem salfa na fosforas ol i save bosim gut long mekim ol samting i stap klin. Em i no gat ol gutpela 'alloying elements' insait long en, na i gat bikpela pe tru. Strong bilong 'tensile' em 370-500 MPa, strong bilong 'yield' em 235 MPa na 345 MPa, 'elongation' bihain long bruk em i bikpela moa o wankain olsem 21%, na 'impact energy' i inapim ol samting we i mas kamap long 'rum temperature impact'.
Low-alloy high-strength structural steel: Long low-carbon steel, sapos ol i putim liklik hap bilong ol alloy elements (Mn, Si, Nb, V, Ti, na ol narapela) i save mekim strong bilong en i kamap gutpela moa, na tu, i gat gutpela 'plasticity', 'toughness', na 'processability'. Liklik kabon i mekim na ol i ken weldim na strong; taim ol i putim ol liklik samting bilong 'alloying elements' dispela i save mekim ol 'grain' i kamap gutpela moa, na dispela i save mekim ol i kamap strong na i no hat tumas; strongpela 'sulfur' na 'phosphorus' kontrol i save strongim 'fatigue' na 'fracture resistance', na dispela i mekim em i gutpela long ol 'high-strength, laitweit straksel disain. Strong bilong 'yield' em 355MPa-460MPa, strong bilong 'tensile' 470MPa-650MPa, na gutpela 'low-'tempereture impact toughness, we i gutpela long yusim long ol ples we i gat -20 digri i go inap long -40 digri.
Struktural steel we i save bagarapim win: Taim ol i putim ol samting olsem Cu, P, Cr, na Ni, wanpela strongpela na strongpela 'rust layer' i save kamap long win, na dispela i save daunim tru 'corrosion rate'. Em i gutpela tru long ol ples we i gat planti hevi olsem sol long nambis, polusen bilong ol indastri, bikpela humiditi, na asid ren. I gat ol samting we i no inap bagarap olsem kopa, kromiam, nikel, na fosforas, na wanpela gutpela 'pasivation film' inap kamap hariap long pes bilong en, na dispela inap long stopim bagarap long go insait. Liklik kabon insait long en i mekim na em i ken wok gut wantaim welding na galvanising. Em i gutpela long ol ples klostu long nambis, ol ailan, ol hap we ol i save tromoi sol, ol hap we ol i save wokim ol kemikel, ol hap we ol i save wokim ol indastri, na ol hap we i gat 'sulfide- polusen.
Strongpela 'alloy structural steel': Sapos ol i yusim 'Strain Triangle Yoke Plate' long ol 'extra-long span o 'super-hevi lod lain, orait ol i mas makim 'high-strength alloy structural steel. Em i gat ol 'alloying elements' olsem Cr, Mo, na Mn, i gat ol bikpela 'comprehensive mechanical properties', gutpela 'hardenability', na 'top-' strong, strong, na 'fatigue' pefomens.
