近些年来,聚乙烯绝缘(TП)市话电缆经历了一些重大修改,目前约占到供各地区电缆网用的现有市话电缆生产量的80％。已出现了采用憎水填充料的电缆;异向扭绞代替了单向扭绞;停止了四芯扭绞电缆的生产;除采用实心聚乙烯绝缘外,同时也采用泡沫聚乙烯绝缘。在ГOCT(全苏国定标准)中推行五种修改方案代替以前的八种方案,生产了22种型号电缆。在本文中,应戈尔洛夫卡市顿巴斯动力基地电工别雷依、列宁格勒市技术科学候补博士克莱辛诺依、水利煤炭自动化研究所工程师利斯特温斯基等的请求,阐述了(TП)型电缆的基本修改方案及其在标准化文件中的反映情况。
In recent years, polyethylene insulated (TП) municipal cables have undergone some major changes and currently account for about 80% of the current production of local cables for cable networks in various regions. Cables that use hydrophobic fillers have emerged; shrouds replace unidirectional twisting; halt the production of four-core twisted cables; and use polyethylene foam insulation, in addition to solid polyethylene insulation. In the ГOCT (All Su-set standards) to implement five modifications to replace the previous eight programs, producing 22 kinds of cables. In this paper, at the request of the electrician Berediger in Donbasa Power Station in Gorlovka, Kleininhoi, candidate candidate for technical scientific lending at Leningrad, and Liskevinski, an engineer at the Institute of Water Conservancy and Coal Automation , Elaborated the basic modification plan of (TП) type cable and its reflection in the standardization document.
