电线电缆产品主要分为五大类:
Wire and cable products are mainly divided into five categories:
1、裸电线及裸导体制品本类产品的主要特征是：纯的导体金属，无绝缘及护套层，如钢芯铝绞线、铜铝汇流排、电力机车线等；加工工艺主要是压力加工，如熔炼、压延、拉制、绞合/紧压绞合等；产品主要用在城郊、农村、用户主线、开关柜等。
1. Bare wire and bare conductor products the main features of this kind of products are: pure conductor metal, no insulation and sheath layer, such as steel cored aluminum strand, copper aluminum bus bar, electric locomotive line, etc; The processing technology is mainly pressure processing, such as melting, calendering, drawing, stranding / compression stranding, etc; The products are mainly used in suburban, rural, user main line, switch cabinet, etc.
2、电力电缆本类产品主要特征是：在导体外挤(绕)包绝缘层，如架空绝缘电缆，或几芯绞合(对应电力系统的相线、零线和地线),如二芯以上架空绝缘电缆，或再增加护套层，如塑料/橡套电线电缆。主要的工艺技术有拉制、绞合、绝缘挤出(绕包)、成缆、铠装、护层挤出等，各种产品的不同工序组合有一定区别。产品主要用在发、配、输、变、供电线路中的强电电能传定网站建设  伺服液位仪  防撞墙模具 唐山护栏 遮阳网 输，通过的电流大(几十安至几千安)、电压高(220V至500kV及以上)。
2. The main features of this kind of power cable products are: extruding (winding) the insulation layer outside the conductor, such as overhead insulated cable, or several cores stranded (corresponding to the phase line, zero line and ground wire of power system), such as overhead insulated cable with more than two cores, or adding sheath layer, such as plastic / rubber sheathed power line cable. The main process technologies include drawing, stranding, insulation extrusion (wrapping), cable forming, armor, sheath extrusion, etc. different process combinations of various products are different. The products are mainly used for strong electric energy transmission in power generation, distribution, transmission, transformation and power supply lines, with large current (tens of amps to thousands of AMPS) and high voltage (220V to 500kV and above)
