Product Description
Porcelain disc suspension insulator is designed to be assembled together to be insulator strings (also called strain insulators), which can divide into Ball & Socket Type and Clevis & Tongue Type.
This structure enables them form the insulator string by fitting into themselves one another as per voltage requirement.
Porcelain pin type insulator is mounted on a pin on the cross-arm on the pole. There is a groove on the upper end of the insulator. The conductor passes through this groove and is tied to the insulator with annealed wire of the same material as the conductor. Pin type insulators are used for transmission and distribution of electric power at voltages up to 33 kV. Beyond operating voltage of 33 kV, the pin type insulators become too bulky and hence uneconomical.
NJREC manufacturers three classes of pin type insulators. Low voltage pin types are manufactured and tested to the requirements of ANSI Standard C29.5, high voltage pin types to ANSI Standard C29.6, and special designs for use in areas of high contamination.
This structure enables them form the insulator string by fitting into themselves one another as per voltage requirement.
