High Voltage Electric Ntauwd fabrication siv Q345B siab-tensile steel nrog qhov tsawg kawg nkaus tawm lub zog ntawm 345 MPa los tswj cov kab ntev ntev heev. Txhua yam khoom raug kho nrog kub -dip galvanization mus rau qhov tsawg kawg nkaus thickness ntawm 86μm rau ISO 1461 tus qauv, ua kom lub neej kev pab ntau tshaj 50 xyoo. Cov qauv no yog tsim los tiv thaiv cua ceev txog li 50m / s thiab 20mm ice loading, uas zoo txo lub hauv paus pob zeb ntim los ntawm 15-20% piv rau cov tsoos tubular ncej.

Daim ntawv thov sib txawv Grid
National Grid Expansion: Txhawb nqa ultra-high voltage (UHV) qaum kab rau kev xa hluav taws xob ntau dhau qhov kev ncua deb tshaj 1,000 km.
Industrial Feeders: Muab siab rau siab - muaj peev xwm kis tau tus mob rau lub zog- cov haujlwm hnyav xws li mining, smelting, thiab hnyav manufacturing.
Loj -Span Hla: Cov qauv tsim kho kom muaj kev ruaj ntseg ntawm tus neeg xyuas pib hla dej ntws, hav, thiab txoj kev loj uas muaj qhov ntev tshaj 500 meters.
Kev Siv Hluav Taws Xob Txuas Ntxiv: Txuas qhov loj - thaj chaw thaj chaw cua thiab hnub ci ua liaj ua teb rau cov chaw hauv cheeb tsam uas siv ntau - kev teeb tsa hauv Circuit Court.
Peb lub Hoobkas
Hebei Yifeng Steel Structure Co., Ltd. ua haujlwm siab - muaj peev xwm tsim khoom hauv Jing County nruab nrog 12 automated CNC kaum steel ntau lawm kab. Peb ua tiav qhov chaw qhov tseeb ntawm ± 0.5mm, kom ntseeg tau tias tag nrho cov khoom sib xyaw ua ke kom nrawm nrawm ntawm - qhov chaw sib dhos. Raws li cov chaw tsim khoom ncaj qha, peb muab kev hloov kho tag nrho ntawm ntauwd qhov siab thiab lub peev xwm thauj khoom raws li cov ntaub ntawv tshwj xeeb hauv cheeb tsam cua siab thaum muab cov neeg siv khoom lag luam nrog kev sib tw Hoobkas- tus nqi ncaj qha thiab cov sij hawm ua cov khoom lag luam.
