在电力系统中，电缆以其施工维护方便、供电可靠性高等特点得以广泛应用。冷缩电缆头由于现场施工简单方便，其冷缩管具有弹性，只要抽出内芯尼龙支撑条，即可紧紧贴服在电缆上，不需要使用加热工具，克服了热缩材料在电缆运行时，因热胀冷缩而产生的热缩材料与电缆本体之间的间隙，因而得到了越来越广泛的应用。
In power system, cable is widely used because of its convenient construction and maintenance, high reliability of power supply. Due to the simple and convenient field construction, the cold shrinkable tube of the cold shrinkable cable head is elastic. As long as the inner core nylon support strip is pulled out, it can be tightly attached to the cable, without the use of heating tools, which overcomes the gap between the heat shrinkable material and the cable body caused by the heat expansion and cold shrinkage during the operation of the cable, so it is more and more widely used.
一、冷缩电缆头制作的基本工艺原理
1、 Basic process principle of making cold shrink cable head
利用冷缩管的收缩性，使冷缩管与电缆完全紧贴，同时用半导体自粘带密封端口，型线  流水槽模具 景观石 检查井钢模具 保定通风管道 隔离墩模具 保定保洁公司y close to the cable. At the same time, the semiconductor self-adhesive tape is used to seal the port, so that it has good insulation, waterproof and moisture-proof effect.
