Hoobkas Nqe tus pin hom porcelain isolators SHF20GS1
| HV porcelain pin insulator ntawm SHF20G1 hom | |||
| Muaj peb qhov kev hloov kho ntawm lub insulator tom qab nws txoj kev sib txuas: nrog polyethylene capsule, nrog cov khoom sib xyaw xov sib haum rau cov kev xav tau ntawm SFS (Finland) tus qauv thiab BS (Great Britain) - lub taub hau me me. Insulator raws li TU 3493-170-00111120-2000 yuav tsum tau. | |||
