| Abstract: |
| A water barrier was extruded on the insulation layer of electric cable to improve electric property and to lower the cost.The formula of the water barrier was given as follows:ACM 100；curatives 10.0-12.0；magnesium oxide 6.0-8.0；antidegradant 2.5-3.0；carbon black 40-45；slippery white powder Lee and calcium carbonate 90-105；A certain level of rubber processing aid WB series was also added into the compound.It was found through the test that good physical properties and processibility of water barrier，as well as significant economic and social benifits were obtained. |
