What exactly is LED?

Faced with this familiar and unfamiliar name, some people who know the truth may say that it is an abbreviation for English LED; others would say that it is a human-made stone and a stone that glows.

But no matter what LED is? It has penetrated into every corner of our lives. Every moment, you always have the opportunity to get in touch with it. It's just that you never noticed its existence, because LED has always been the unsung hero in our lives.

Now the hero is moving from behind the scenes to the stage, ready to show his talents in the field of lighting.

Composite Insulator is an electrical device consisting of insulation section made of polymer materials and metal fittings, Silicone rubber is the most widely used polymeric insulation material for high voltage products. Composite polymer insulator can play an important role in overhead transmission lines.  Electric composite  insulator can be divided into: Suspension Composite Insulator,Composite Long Rod Insulator, Pin Type Composite Insulator and Line Post Composite Insulator.

As the replacement of porcelain insulators, silicone rubber composite insulators have many advantages:

1.Low costs (or no necessity at all) for Insulators cleaning
2.No need of zero value check, suitable for difficult maintenance area
3.Light weight, easy and economical to transportation and installation
4.Not brittle, and reduce the purchasing quantities for spare parts
