Product Description
Nanjing Rainbow Electric Co.,Ltd Porcelain Stay Insulators/Guy Strain Insulators are manufactured from wet process porcelain to ensure a life time of trouble free service. These insulators are designed to be compatible with pre formed style guy grips. They are designed, manufactured and tested in conformance with ANSI Standard C29.4.
Porcelain Stay Insulators of ANSI 54-1, 54-2, 54-3, 54-4.
Standard color is brown, sky gray, with chocolate available upon request.
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.
