摘要： A bullet-proof board includes a pair of steel plates of substantially identical thicknesses that sandwich a thick intermediate layer therebetween and a thin surface layer secured to that steel plate surface which faces a striking bullet. The intermediate and surface layers are made of such chemical fiber cloths or synthetic resin plates which absorb energy of a striking bullet. The bullet-proof board may be formed in the shape of a sidewall of a truncated-cone and secured to a suspension insulator for protecting it against gun shooting.A bullet-proof insulator assembly includes an insulator string formed of suspension insulators coupled to each other, bullet-proof rings, one of which is mounted on each of the suspension insulators, each bullet-proof ring having a shape representing a sidewall of a truncated-cone with a minimum inside diameter larger than the outside diameter of the shed portion of the suspension insulator, and holders mounting the bullet-proof rings to the suspension insulators in such a manner that each bullet-proof ring extends away from a longitudinal axis of the insulator string at an angle of 45-70 degrees relative to the longitudinal axis as the bullet-proof ring extends upwardly and that the minimum distance between adjacent bullet-proof rings (L) is longer than the minimum distance between adjacent suspension insulators (l).

摘要翻译： 防弹板包括一对厚度大致相同的钢板，夹在其间的厚中间层和固定在该钢板表面上的薄表面层，该表面层面向冲击的子弹。 中间层和表面层由吸收醒目子弹能量的化学纤维布或合成树脂板制成。 防弹板可以形成为截锥形的侧壁的形状，并且固定到悬挂绝缘体以保护其免受枪射击。 防弹绝缘体组件包括由彼此耦合的悬挂绝缘体形成的绝缘体串，防弹环，其中一个安装在每个悬挂绝缘体上，每个防弹环具有表示截断的侧壁的形状 - 具有大于悬挂绝缘体的棚部的外径的最小内径，以及将防弹环安装到悬挂绝缘体的保持器，使得每个防弹环从纵向轴线延伸远离 当防弹环向上延伸时，绝缘子串相对于纵向轴线成45-70度的角度，并且相邻防弹环（L）之间的最小距离比相邻悬挂绝缘体之间的最小距离长（l ）。
