- 摘要：
- <p>FIELD: electricity. ^ SUBSTANCE: housing has inner layer and outer layer. Thickness of inner layer is at least by 50% more than thickness of outer layer, and inner layer is more flexible than outer layer. Inner layer is made from composition of the first resin which at hardening has relative elongation at rupture which is more than 5%, and outer layer is made from composition of the second resin which at hardening has relative elongation at rupture which is less than 5%. ^ EFFECT: improving insulation and strength properties of electric item, and profitability of its manufacture. ^ 14 cl, 2 dwg</p>
