Transmission Ceramic Insulators

Our offer includes solutions in isolation and protective equipment for use distribution and transmission of energy.

Transmission ceramic insulators.

Insulators used for high voltage power transmission are made from glass porcelain or composite polymer materials. This type was amongst the earliest designs and used for support ing line conductors. We offer suspension line post braced post bell equivalents and custom insulator assemblies. We can t find products matching the selection.

Table 2 shows the typical number of insulators used by utilities in the u s. Our entire interactive transmission catalog is also available for your viewing. In a 11 kv system we generally use one part type insulator where whole pin insulator is one piece of properly shaped porcelain or glass. Insulators are used in electrical equipment to support and separate electrical conductors without allowing current through themselves.

The term insulator is also used more specifically to refer to insulating supports used to attach electric power distribution or transmission. Pin insulators are the earliest developed overhead insulator but are still commonly used in power networks up to 33 kv system. Various types of insulators used for overhead transmission and distribution lines are described below. However the majority of post insulators.

There is a. Lapp insulators produces high quality products for high voltage and railway electricity networks since 1930. The part sec tion of a pin type insulator is shown in fig. An insulating material used in bulk to wrap electrical cables or other equipment is called insulation.

There are several types of insulators in transmission lines but the most commonly used are pin type suspension type strain insulator and shackle insulator. As the name suggests the pin type insulator is secured to the cross arm on the pole. Post type insulators are used for medium voltage and low voltage transmission lines where insulators replace the cross arm. All of which are manufactured under international standards such as iec and ansi among others.

Get a quote for. Pin type insulator can be one part two parts or three parts type depending upon application voltage. And canada in lightly polluted areas. Post type insulators figure 4 composite line post insulators.

Insulators made from porcelain rich in alumina are used where high mechanical strength is a criterion. 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.
