直流电压试验作为一种对油浸纸绝缘电缆非常有效的方法应用至今，但它对塑料绝缘电缆是无效而且有害的。
The DC test, which is an effective means for the diagnostics of oil impregnated paper insulated cable, is still used even now, but it is ineffective and harmful for the plastic insulated cable.
尽管早期对塑料电缆寄予希望，但对于较高电压，最有效的绝缘仍采用油纸组合绝缘。
In spite of earlier hopes for plastic insulations, the combination of paper and oil still forms the most effective dielectric at the higher voltages.
也可以制作PVC发泡板，PVC吊顶，PVC水管，PVC踢脚线以及穿线管，电缆绝缘，塑料门窗，塑料袋等方面。
You can also make PVC foam board, PVC ceiling, PVC pipes, PVC baseboard and threading pipe, cable insulation, plastic doors and windows, plastic bags and so on.
当你将电缆穿孔时，电缆在两个金属锯齿中下沉，这样就将电缆的塑料绝缘套剥离。
As you punch it down, the cable descends between the two metal teeth, which remove its plastic insulation (it's called insulation displacement) and the cable is cut.
