6KV及以上電纜接頭：①安裝電纜終端頭時(shí)，必須剝除半導(dǎo)體電屏蔽層，操作時(shí)不得損傷絕緣，應(yīng)避免刀痕凹凸不平的情況，必要時(shí)用砂紙磨平；屏蔽端部應(yīng)平整，并要把石墨層（碳粒）清除干凈。②塑料絕緣電纜端頭銅帶屏蔽和鋼鎧必須良好接地，對(duì)短路也遵循這項(xiàng)原則，避免三相不平衡運(yùn)行時(shí)鋼鎧端部產(chǎn)生感應(yīng)電動(dòng)勢(shì)，甚至“打火”及燃燒護(hù)套等事故。
三菱pIc的傳送指令MOV,和比較指令CMP程序設(shè)計(jì)中Zui常用的指令。學(xué)會(huì)掌握這兩個(gè)指令將會(huì)使程序設(shè)計(jì)更簡(jiǎn)單，設(shè)計(jì)出的程序更顯智能化。MOV指令：MOV指令是功能指令中的基礎(chǔ)指令，是Zui常用的指令。MOV傳送指令簡(jiǎn)單說(shuō)就是把一個(gè)值賦予另一個(gè)值。我們把被傳送值叫源址S。那么S里有哪些操作數(shù)（被傳送值）呢？它包括KnX，KnY，KnM，KnS，T，C，D，V，Z，K，H。被傳送值傳送到的地址為D。那么D有那些數(shù)值呢？KnY，KnM，KnS，T，C，D，V，Z。

The cross section of the control cable is generally no more than 10square meters, and the power cable is mainly used to transportpower, which is generally large. Due to the above all when it comesto the reason, the specifications of the power cable can generallylarger, to 500 square feet (normal manufacturer can produce range),again big cross section of the general factory is relatively less,you can do and control cable section generally small, generally notmore than 10 largest square, tell from some cable, power cableaccording to the request of power grid, most commonly for fivecore, and control cable transmission control signal, some more,according to the standard terms of more than 61 core, but also canproduce according to user re
常用全塑電纜規(guī)格代號(hào)的意義一般常用全塑電纜規(guī)格代號(hào)排在電纜型號(hào)的后面，常用數(shù)字表示。（2）市內(nèi)用市話全塑電纜的結(jié)構(gòu)（H）凡是電纜的芯線絕緣層、纜心包帶層和護(hù)套，均采用高分子聚合物塑料制成的，就稱為全塑電纜。
