例如，立式灯具不仅要经受飞机尾流的巨大吹力，还要在被飞机撞及时能立即倾倒；平地式灯具要能承受飞机的压力和风雪酷暑的轮番作用。
由于机场灯在结构上的特殊要求，许多国家都制订了严格的灯具规范并付诸实施。

电力电缆得到越来越广的应用。
1911年，德国敷设成60千伏高压电缆，开始了高压电缆的发展。
1913年，德国人M.霍希施泰特研制成分相屏蔽电缆,改善了电缆内部电厂分布,消除了绝缘表面的正切应力，成为电力电缆发展中的里程碑。
Computer shielded cable; Purpose: high voltage insulation with small interface constant. Use to ground, and the screen, the total screen (or three quad twisted, group screening, group screen a total screen), such as structure form, with a small dielectric loss, the transmission ability is strong, resistant performance is good wait for a characteristic, can reliable transmission weak analog or digital, can be widely used in electricity, metallurgy, petroleum, chemical, textile sites detection and control of the door or by computer automation instrumentation, and general industrial computer.
