You might have seen these glass or porcelain things on the tops and crossarms of telephone poles, but have you ever wondered what they are and why they’re there? Well, hang tight, because I’m about to spill the beans on these unsung heroes of the communication world.
Insulators, those quirky-looking contraptions, have a vital job. Their purpose is to keep the electrical wires they cradle from having a little chat with the pole or, heaven forbid, the earth below. If they didn’t do their job, all that electricity (or those precious telephone calls) would just leak away. Imagine trying to make a long-distance call when your voice fizzles out after a few hundred feet. Not fun, right?
You’ll find a treasure trove of insulator styles and colors. While many of the older ones were made from glass or porcelain, some were crafted from wood and glass, animal parts (yes, you read that right), and even more bizarre materials. Size matters, too – smaller insulators hung out with the telephone and telegraph crowds, while their larger counterparts partied with the high-voltage electrical wires. It’s like a VIP section for insulators, depending on the voltage!
