Who makes porcelain insulators?
PPC Insulators is a technology leader and manufacturer of state-of-the-art electrical porcelain insulators for overhead transmission lines, substations and electrostatic precipitator applications. Traditional porcelain insulators originated in the late 19th century.
What insulators are used in High Voltage?
Insulators used for high-voltage power transmission are made from glass, porcelain or composite polymer materials. Porcelain insulators are made from clay, quartz or alumina and feldspar, and are covered with a smooth glaze to shed water.
Is porcelain the best insulator?
Porcelain Properties Since porcelain does not conduct electricity, especially when combined with other non-conductive materials, it makes the ideal material for insulators.
What is the best insulator of electricity in the world?
The most effective electrical insulators are:
- Rubber.
- Glass.
- Pure water.
- Oil.
- Air.
- Diamond.
- Dry wood.
- Dry cotton.
Where did the name porcelain come from?
The word porcelain is derived from porcellana, used by Marco Polo to describe the pottery he saw in China. The three main types of porcelain are true, or hard-paste, porcelain; artificial, or soft-paste, porcelain; and bone china.

How many insulators are in a kV?
We generally use two parts pin insulators for 33KV, and three parts pin insulator for 66KV systems.
Why is ceramic not a good insulator?
Electrical current in solids is most often the result of the flow of electrons (electronic conduction). In contrast, valence electrons in ceramic materials are usually not in the conduction band, thus most ceramics are considered insulators. However, conductivity can be increased by doping the material with impurities.
What insulators keep something hot?
Metals are good conductors of heat. Air is a good insulator; so things which have air trapped in them, like cotton wool, sponge, fibre glass, fur and feathers, are good insulators. This is how animals and birds keep warm; but humans need clothes to keep warm.
Why is porcelain so expensive?
That makes porcelain more durable and more water resistant than ceramics, UNESCO notes (and Home Depot seconds!) As for why porcelain is more expensive than regular china, it’s because making porcelain truly is an art form.
