Mphete yonyamulira ya UX yotenthetsera

Mphete yonyamulira yooneka ngati U imapangidwa kuchokera kuzitsulo zozungulira ndipo imakhala ndi ntchito zambiri. Ikhoza kugwiritsidwa ntchito yokha kapena kuikidwa ndi mphete ziwiri pamndandanda.1 Mtundu wa kukula kwa 1.1 mphete yopachikika yooneka ngati U ndi U-mawonekedwe, mawonekedwe a UL.
1.2 Miyeso yayikulu ya mphete yopachikika yooneka ngati U iyenera kukwaniritsa zofunikira zomwe zasonyezedwa mu Chithunzi 1 ndi tebulo ili:
chithunzi 1
Chithunzi 1
Tanthauzo la zilembo ndi manambala mu zitsanzo zomwe zili patebulo ndi:
U——U-mawonekedwe; L——yakulitsidwa; Nambala——chizindikiro chodziŵika cholephera. 
2 Zofunikira zaukadaulo
2.1 Makhalidwe aukadaulo a mphete yolendewera yooneka ngati U azitsatira zomwe GB2314-85 "General Technical Requirements for Electric Power Fittings".
2.2 Kukula kolumikizana kwa mphete yopachikika yooneka ngati U kudzatsatira zofunikira za GB2315-85 "Nominal Damage Load Series of Power Fittings and Connection Dimensions of Parts".
2.3 Kupanga, kupanga, kuyesa, kuvomereza, kuyika chizindikiro ndi kuyika mphete yolendewera yooneka ngati U iyenera kutsatira zofunikira za DL/T759-2009 Electric Power Industry Standard "Connecting Fittings".
2.3 Zida ndi zomangira:
a. Thupi lopachikika lopachikidwa lopangidwa ndi U limapangidwa ndi chitsulo chokhala ndi mphamvu yosachepera 372.5N/mm2 (372.5MPa) malinga ndi GB700-79 "Technical Conditions for Common Carbon Structural Steels";
b. Mtedzawo umagwirizana ndi GB 41-76 "Hexagon Nut (Yoyipa)";
c. Ma bolts ali molingana ndi SD 25-82 "maboti amutu a Hexagon okhala ndi mabowo a pini";
d. Pini yotseka ikugwirizana ndi SD 26-82 "Pini yotsekedwa".
2.4 Kuwonongeka kwa mphete yopachikika yooneka ngati U sikuyenera kukhala yayikulu kuposa izi:
U-7, UL-7 mtundu 69kN;
U-10, UL-10 mtundu 98kN;
U-12 mtundu 118kN;

3 Malamulo ovomerezeka ndi njira zoyesera
Kuvomereza ndi kuyesedwa kwa mphete yopachikika yooneka ngati U kudzachitidwa molingana ndi GB2317-85 "Malamulo Ovomerezeka, Njira Zoyesera, Kulemba ndi Kuyika kwa Magetsi a Magetsi".
4 Kulemba ndi kulongedza katundu
Kuyika ndi kuyika kwa mphete yopachikika yooneka ngati U kudzachitika molingana ndi zomwe GB 2317-85.
