PIN INSULATOR
The pin insulator is a type of distribution line insulator, which is mounted to an electrical cross arm of the utility pole with the support of various bolts or pole top pins.
Pin insulator is widely used in the power distribution systems with the features of low price, high mechanical strength, simple design, and easy maintenance.
Pin type insulators are assembled on the top of the electrical poles or towers. The conductor was fixed to the grooves on the upper end of the insulators, with the help of the top tie.
Pin type insulator can be made of ceramic, porcelain, polymer, glass, or silicon rubber.
For lower voltages one-piece type of insulators are enough, For the application of higher voltage, stronger pin type insulators such as two pieces or three pieces types are needed.
Due to its design, It is generally used for the voltage 11kv up to 33kv, pin Insulators beyond a voltage of 33 kV will be bulky and expensive.
Pin Insulator Applications:
- This insulator is used in power transmission lines for up to 33kV.
- These insulators are used on intermediate poles on a straight run
- Instead of using two suspension type insulators, pin type insulator is used.
Pin Insulator Features:
- The pin type insulator has a good creepage distance.
- The mechanical resistance is high.
- It is used on the distribution line for high voltage.
- The design and maintenance of the pin insulator form are clear.
- It can be used both horizontally and vertically.
Pin Insulator Specifications:
Customized according to customer needs
