Insulators made from porcelain rich in alumina are used where high mechanical strength is a criterion.
Transmission ceramic insulators.
It provides the most economic simple and efficient method of conductor and bus bar support for voltages up to and including 33 kv.
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.
Insulators are used in electrical equipment to support and separate electrical conductors without allowing current through themselves.
Post type insulators are used for medium voltage and low voltage transmission lines where insulators replace the cross arm.
The part sec tion of a pin type insulator is shown in fig.
Pin insulators are the earliest developed overhead insulator but are still commonly used in power networks up to 33 kv system.
Our entire interactive transmission catalog is also available for your viewing.
All of which are manufactured under international standards such as iec and ansi among others.
Pin type insulator can be one part two parts or three parts type depending upon application voltage.
Porcelain insulators are made from clay quartz or alumina and feldspar and are covered with a smooth glaze to shed water.
Lapp insulators produces high quality products for high voltage and railway electricity networks since 1930.
The term insulator is also used more specifically to refer to insulating supports used to attach electric power distribution or transmission.
There are several types of insulators in transmission lines but the most commonly used are pin type suspension type strain insulator and shackle insulator.
This type was amongst the earliest designs and used for support ing line conductors.
Insulators used for high voltage power transmission are made from glass porcelain or composite polymer materials.
An insulating material used in bulk to wrap electrical cables or other equipment is called insulation.
Our offer includes solutions in isolation and protective equipment for use distribution and transmission of energy.
