COMPOSITE PIN INSULATORS
A pin insulator is a device that isolates a wire from a physical support such as a pin (a wooden or metal dowel of about 3cm diameter
with screw threads) on a telegraph or utility pole. It is a formed, single layer shape that is made out of a non-conducting material,
usually porcelain or glass. It is thought to be the earliest developed overhead insulator and is still popularly used in power networks up
to 33kV. Single or multiple pin insulators can be used on one physical support, however, the number of insulators used depends upon
the application's voltage.
Advantages:
Composite pin insulator has high resistance to bending, impact, shock and explosion.The inner insulation is reliable and light weight,
which is an ideal replacement for the traditional tempered glass insulators.
