Insulators are used in electrical equipment to support and separate electrical conductors without allowing current through themselves. An insulating material used in bulk to wrap electrical cables or other equipment is called insulation. The term insulator is also used more specifically to refer to insulating supports used to attach electric power distribution or transmission lines to utility poles and transmission towers. They support the weight of the suspended wires without allowing the current to flow through the tower to ground.
Our insulators for transmission lines are produced in accordance with international standards and the respective customer specification for applications in the area of energy distribution and transmission in mechanical classes up to 400 KN tensile forces. In addition, we also design entire insulator chains from long rods. To improve the outer layer properties our products are also available with silicone coating.
Electrical ceramic insulators are the absence of electrical conduction. Electronic band theory (a branch of physics) says that a charge flows if states are available into which electrons can be excited. This allows electrons to gain energy and thereby move through a conductor such as a metal. If no such states are available, the material is an insulator.
Older dry process insulators were sometimes embossed. Like with glass insulators, markings were engraved into the mold, and when pressed the letters would be raised on the insulator surface. A number of earlier Ohio Brass styles are also embossed.
Under glaze ink marked insulators are stamped with an ink pad prior to glazing. The glaze does not hide the mark completely, and so a permanent identification is made. This method is commonly used at present.
There are also many different materials of the high quality porcelain insulators available in our factory, welcome to visit and the best services for you!
