nd when Elizabeth ascended the throne, Pickering thought proper to he a long diplomatic illness at Dunkirk, to learn how he would be received in England after his more than douful dealings. As soon as he was satisfied that bygones would be bygones, he came to England in fine feather. Tiepolo writes to the Doge, February 23rd: “Concerning her marriage it still continues to be said that she will take that Master Pickering, who from information received by me, is about thirty-six years of age, of tall stature, handsome, and very successful with women, for he is said to he enj

I can assure your Majesty that matters he reached such a pass that I he been brought to consider whether it would not be well to approach Lord Robert on your Majesty’s behalf, promising him your help and four and coming to terms with him.” At the same time the Swedish ambassador was again pressing the suit of Prince Eric; but he must he been extremely maladroit, for he offended Elizabeth at the outset by saying that his ’s son was still of the same mind, and asked for a reply to the letter he had sent her. “What letter?” said the Queen. “The letter I brought your Majesty.” Elizabeth replied that she was now Queen of England, and if he required an answer he must address her as such. She added that she did not know whether his would lee his kingdom to marry her, but she could assure him that she would not lee

采掘工業(yè)用電線電纜(礦用橡套軟電纜)礦用電纜 MYQ 0.3/0.5KV 2×1.0
采掘電線電纜是供地下或地面各種礦藏(煤、金屬、非金屬礦)開采設(shè)備、工具用的一類產(chǎn)品。由于地下煤礦的環(huán)境條件為復(fù)雜(有瓦斯氣),因此產(chǎn)品性能要求以按煤礦的條件為主,所以通稱礦用電線電纜。其品種除采煤機(jī)電纜還有礦用移動(dòng)橡套電纜,電鉆電纜,礦用控制電纜,礦用通信電纜,采掘機(jī)電纜(UGF電纜)。礦用動(dòng)力線路用電纜在結(jié)構(gòu)上要滿足耐沖擊(大礦石砸下)、耐擠壓(礦車)等要求,并有防止引起瓦斯爆炸的保護(hù)結(jié)構(gòu)(與繼電保護(hù)相連),阻燃要求也較高。
采煤機(jī)橡套軟電纜(MC,MCP,MCPT)動(dòng)力線芯3,地線芯1,控制線芯3-7;適用于采煤機(jī)電源線。
礦用橡套電纜結(jié)構(gòu)特點(diǎn):一:導(dǎo)電線芯。柔軟性要求以電鉆電纜,采掘機(jī)電纜為高;導(dǎo)線結(jié)構(gòu)采取如下措施:1,采用較軟的細(xì)直徑銅單線、以小節(jié)距束合、復(fù)絞。整根電纜的彎曲扭轉(zhuǎn)性還受到絕緣、護(hù)套結(jié)構(gòu)的影響,因此不能認(rèn)為單絲越細(xì),節(jié)距越小越好。2,采用同向束絞和復(fù)絞可提高柔軟性。3,為了便于導(dǎo)線在絕緣層中的相對(duì)滑動(dòng)和便于安裝維修。電鉆電纜和小截面的采掘機(jī)電纜導(dǎo)線單絲應(yīng)鍍錫,大截面采掘機(jī)電纜在導(dǎo)線外還用包紙帶隔離絕緣。二:絕緣層要求有足夠的電絕緣性能1,采用含膠量不低于百分之35的橡皮2,絕緣厚度比通用橡套電纜要厚3,采用電性好的橡皮,并采用好的擠橡工藝(如擠橡硫化連續(xù)生產(chǎn)線)
