Pin Post Type Insulator

The different types of insulators are pin type suspension type post type suspension type strain type spool type ceramic type non ceramic type etc thus this is an overview of an insulator it is a material used to oppose the flow of current.

Pin post type insulator.

It is only used in the distribution line. Post insulators are similar to pin insulators but post insulators are more suitable for higher voltage applications. The pin types of insulators are mostly used in the distribution system. Let s dive in each one by one.

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 3 cm 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. The voltage rating is limited i e up to 36kv. It is made up of material which has high mechanical strength. It can be used vertically as well as horizontally.

Specification of pin insulator. The insulator is made of one piece of porcelain and it has clamp arrangement are. High strength 69 kv post horizontal clamp top with long pintle bolt rigid gain base. It should be used with the spindle.

By ohio brass. Beyond operating voltage of 33 kv it becomes to bulky and uneconomical. All neck sizes comply with industry standards. Post insulators have a higher number of petticoats and a greated height compared to pin insulators.

These insulators offer an economical alternative to line post insulators fitting on the same mounting pins as pin type insulators while providing the improved operating characteristics of line. It can be connected with horizontal as. It used only to 33 kv. Factory formed ties can be used.

It is secured to the cross arm on the pole. The construction of the pin type insulator is simple and requires less maintenance. The pin of the insulator damaged the insulator thread. The versatile neck designs in c f k and j side and top grooves accepts large diameter conductors for easy tying.

Pin type insulator it consists of a single or multiple units. Cutouts type c fuse links lighting control relays. There is a groove on the upper end. Ppc manufactures a wide range of low and high voltage pin type insulators designed for distribution.

Disadvantages of pin insulator. We can mount this type of insulator on supporting structure horizontally as well as vertically.
