How much is a kilogram of second-hand cable recycled ☎ 15075225912 “how much is the recovery of copper core cable? How much is the recovery of Bengbu high voltage cable? (2) select the cable section according to the economic current density: the calculation method is the same as that of the conductor section* 1) Izmax — the maximum load current (a) that the cable passes through for a long time
. 
How much does Bengbu cable recycling company pay for a ton of na-vv22, nb-vv22, PVC insulated steel strip armored, PVC sheathed a (b) fire resistant power cables, which are suitable for buried laying when fire resistance is required, but not suitable for laying in pipelines
. 
XLPE insulated cable is a kind of cable suitable for distribution network and other fields, which has incomparable advantages over PVC insulated cable
. 
It has the advantages of simple structure, light weight, good heat resistance, strong load capacity, non melting, chemical corrosion resistance and high mechanical strength., Bazhou cable recycling, Yangzhong cable recycling, Yanshi cable recycling, Anshun cable recycling, Laiyang cable recycling, Tai’an cable recycling, Guixi cable recycling, Daqing cable recycling, Xuzhou cable recycling, Fuxin cable recycling, Yichun cable recycling, Zhangshu cable recycling, Wusu cable recycling, Xingcheng cable recycling, Zixing cable recycling, Turpan cable recycling, Zhangye cable recycling, Weifang cable recycling, Nanxiong cable recycling, Wuwei cable recycling, Jiangshan cable recycling, Zhangjiajie cable recycling, Ji’an cable recycling, Hegang cable recycling, Yangzhou cable recycling, Xiangfan cable recycling, Yidu cable recycling, Shaowu cable recycling, Changning cable recycling, Ordos cable recycling, Yuzhou cable recycling, Lingwu cable recycling, Hailin cable recycling, Wuzhong cable recycling, Yibin cable recycling, Qinyang cable recycling, Shenzhou cable recycling, Pingdu cable recycling, Puyang cable recycling, Jiayuguan cable recycling, Taishan cable recycling, Linfen cable recycling, Leping cable recycling, Dezhou cable recycling, Fuyang cable recycling, Quanzhou cable recycling, Hezuo cable recycling, Xiangxiang cable recycling, Jinghong cable recycling, Yizhou cable recycling, Lanxi cable recycling, Kaiping cable recycling, Nanning cable recycling, Longnan cable recycling, Qianjiang cable recycling, Wendeng cable recycling, Beihai cable recycling, Jinchang cable recycling, Shaanxi cable recycling, Hainan cable recycling, Shifang cable recycling, Pingdingshan cable recycling, Laibin cable recycling, Shaoxing cable recycling, Lijiang cable recycling, Shenzhen cable recycling, Yanji cable recycling, Daye cable recycling, Xining cable recycling, Dongtai cable recycling, Kaili cable recycling, Shuangyashan cable recycling, Qingyang cable recycling, Bole cable recycling, Jinjiang cable recycling, Bengbu wire and cable recycling how much is it? The outer sheath is a protective covering layer wrapped outside the cable sheath (inner sheath), which mainly plays the role of mechanical strengthening and anti-corrosion
.
There are two kinds of cables in common use: the outer sheath whose inner sheath is metal sheath and the outer sheath whose inner sheath is plastic sheath
.
The outer protective layer of metal sheath is generally composed of backing layer, armor layer and outer coating layer
.
The liner layer is located between the metal sheath and the armor layer, which plays the role of anti-corrosion of the liner and metal sheath
.
The armor layer is metal belt or wire, which is mainly used for mechanical protection, and the wire can bear tensile force
.
The outer coating layer is outside the armor layer, which has anti-corrosion effect on the metal armor
.
The village cushion and outer cover are composed of asphalt, polyvinyl chloride tape, impregnated paper, polyvinyl chloride or polyethylene sheath, etc
.
According to the different environment and conditions of various cables, the composition and structure of the outer sheath are also different
.
The outer sheath structure of various types of power cables is shown in the table of various cable types
.
