Kev Piav Qhia Luv:

Cov Khoom Nta :: Cov Tshuab Txiav Tsob Ntoo Uas Muaj Cov Khoom Siv Insulated yog qhov tsim nyog rau kev txiav cov ceg ntoo thiab cov ceg ntoo hauv qab cov kab hluav taws xob faib tawm. Cov tshuab txiav ntoo uas muaj cov khoom siv insulated txais yuav lub hauv paus ntsiab lus ntawm cov levers thiab pulley blocks. Lawv tau tsim los ntawm txiab, saws thiab insulating ncej. Cov ncej insulating yog ua los ntawm cov raj insulating muaj zog heev. Cov ncej insulating tuaj yeem hloov kho raws li tus neeg siv xav tau. Nrog rau kev sib txuas ntu lossis telescopic. Qhov siab tshaj plaws ua haujlwm ntawm cov tshuab txiav ntoo insulated yog 6m, qhov qhib siab tshaj plaws ntawm cov txiab yog 38mm, thiab qhov hluav taws xob ntawm kab ua haujlwm tsis siab dua 35kv. Nws yog ib qho cuab yeej zoo tshaj plaws rau lub zog thiab kev tsheb ciav hlau los txiav cov ntoo raws kab hluav taws xob.
