Carbon nanotube is superior to general powder state materials of mechanical and electrical properties. Because its ratio of diameter and length (aspect ratio) is very large, it has been known as a type of ideal nano-reinforcement material. Based on this advantage, existing carbon black of semiconductive shield materials used in power cables can acquire excellent properties by using a small amount...
This study investigate the mechanical, electrical and thermal properties of carbon nanotube in power cable semiconductive shield materials. It acquired high strain and thermal resistance using a little carbon nanotube. This tendency confirm high cross-link density making new network that carbon nanotube between carbon black reconstitute molecule bonding by similar constructive. The semiconductive...
To improve mean-life and reliability of power cable, we have investigated specific heat and thermal conductivity of XLPE insulator and semiconducting materials in 154 kV XLPE cable. Specimens were respectively made of sheet form with EVA, EEA and EBA with carbon black 30 wt%, and the other was made of sheet form by cutting XLPE insulator in certain 154 kV power cable. Specific heat and thermal conductivity...
To decrease and remove of many noises that are detected in PD (partial discharge) measuring test, we forced on detection of those. We made W-LC filter for measuring PD, which adapted that to field test. We tested after design laboratory circumstances like field line, and then the phase change properties of detected signal in UHF sensor were measured by Lemke probe and oscilloscope (TDS-3054, Tektronix)...
To measure elastic properties and surface roughness of semi-conducting materials in power cable, we have investigated modulus and micro-structure of EVA/acetylene black composites that are showed by changing the content of acetylene black. The specimen was primarily kneaded in material samples of pellet form for 5 minutes on rollers of between 70[degC] and 100[degC]. Then this was produced as sheets...
