Yog vim li cas Expansion Joints Installed On Hard Busbars

Cov khoom muaj cov yam ntxwv ntawm thermal expansion thiab contraction, thiab qhov ntev ntawm busbar yuav hloov vim thaum tshav kub kub ua haujlwm.

Txhawm rau kom tsis txhob muaj kev ntxhov siab ntau dhau thiab kev puas tsuaj rau lub busbar thiab kev txhawb nqa insulator vim muaj kev hloov pauv hauv thermal expansion thiab contraction, expansion pob qij txha yuav tsum tau nruab rau ntawm lub hard busbar.
