● Polymer insulator tau los ntawm silicon roj hmab rau gallee cov rwb thaiv tsev sab nraud; lub zog siab nthuav tawm sab hauv rwb thaiv tsev rau cov khoom lag luam thiab siv tshuab txuag hluav taws xob. Cov khoom siv cov thev naus laus zis tshiab, uas nias txuas ntawm pwm, Mandril thiab cov khoom siv hlau uas muaj. Txhim kho cov khoom lag luam, kev ntseeg tau, cov charaters raws li nram no:
● Kev siv hluav taws xob zoo nkauj, kev sib tw me me, lub teeb yuag, zoo heev impulse tiv thaiv, poob siab, thiab tawg tsis taus.
