続部をコンパクトにする検討が種々行なわれている。At the terminals and connections of high-voltage electrical cables, stress can be alleviated by using sleeves or tapes made of so-called low-impedance materials that have a high dielectric constant or low specific resistance, and cover the areas where the electric field is concentrated. Various studies are being conducted to make the terminal portion and the connecting portion more compact.

7〜IQIOの配合を得ることはできなかった。In other words, if only carbon was added to the ethylene-vinyl acetate copolymer as in Comparative Examples E and F, the specific resistance would be 10.
It was not possible to obtain a formulation of 7 to IQIO.
アセチレンブラック20部添加のD配合は加熱なし、1
60°C4日加熱後ともにl Q12で高すぎる。D formulation with 20 parts of acetylene black added: no heating, 1
After heating at 60°C for 4 days, l Q12 was too high.
ア七チレンブラック80部添加のE配合は加熱なしだと
I Q10.160°C4日加熱後106以下と、性能
は非常に不六定であった。For formulation E containing 80 parts of a7ethylene black, the IQ was 10 without heating.IQ was 106 or less after heating for 4 days at 160°C, and the performance was very variable.
ア七チレンブラック40部添加のF配合は加熱なし10
6.160°C4日加熱後106以下と固有抵抗が低く
すぎる。F formulation with 40 parts of atylene black added is 10 without heating.
6. After heating at 160°C for 4 days, the specific resistance is 106 or less, which is too low.
カーボンブラックの種類をかえて種々検討したが、10
7〜101Oの範囲は非常に不安定で、良好なものが得

The range of 7 to 101O was very unstable and good results could not be obtained.
金属粉末やチタン化合物の併用も検討したがやはり10
7〜l QIOのものは得られなかった。We also considered using metal powder and titanium compounds, but the result was still 10.
7-1 QIO was not obtained.
