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.
Pin post type insulator.
The pin of the insulator damaged the insulator thread.
Cutouts type c fuse links lighting control relays.
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.
High strength 69 kv post horizontal clamp top with long pintle bolt rigid gain base.
There is a groove on the upper end.
The insulator is made of one piece of porcelain and it has clamp arrangement are.
Post insulators have a higher number of petticoats and a greated height compared to pin insulators.
It can be connected with horizontal as.
The pin types of insulators are mostly used in the distribution system.
The voltage rating is limited i e up to 36kv.
It is secured to the cross arm on the pole.
Ppc manufactures a wide range of low and high voltage pin type insulators designed for distribution.
It used only to 33 kv.
Beyond operating voltage of 33 kv it becomes to bulky and uneconomical.
The versatile neck designs in c f k and j side and top grooves accepts large diameter conductors for easy tying.
Mity lite horizontal line post insulator.
By ohio brass.
Pin insulator can sustain up to 11kv voltage capacity.
Disadvantages of pin insulator.
The construction of the pin type insulator is simple and requires less maintenance.
Let s dive in each one by one.
All neck sizes comply with industry standards.
We can mount this type of insulator on supporting structure horizontally as well as vertically.
It is only used in the distribution line.
It should be used with the spindle.
Factory formed ties can be used.
It is made up of material which has high mechanical strength.
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.
Specification of pin insulator.
It can be used vertically as well as horizontally.
