There are primarily six types of insulator made use of as electrical transmission and distribution line. Suspension variety insulators are less expensive than pin sort insulators for voltages beyond 33 kV. glass string insulators -flexible towers give saving in steel and are used for single circuit three-phase transmission lines with horizontal conductor configuration. Even so, glass insulators for sale of such insulators is decreasing immediately after increasing the use of underground cables for distribution purpose. They are utilized to manage mechanical stresses and take the stress off a conductor at the finish of a transmission line, at a sharp corner or curve or more than long river crossings. High mechanical strength in order to withstand the conductor load, wind load etc. The detail explanation of the cap and pin and Hewlett form insulator are explained below. The home that distinguishes an insulator is its resistivity insulators have higher resistivity than semiconductors or conductors. three. The suspension insulator of claim 1, wherein mentioned connecting pin is cemented in mentioned inner cavity. In electric glass insulators of suspension disk insulator ,Portland cement is utilised in order to fill up the space in between porcelain & metal hardware exactly where the cement acts as a compression-resistant the compression strength of cement at an elevated temp is of interest in the present study.
