High Voltage Pin Type Insulator

It is made up of material which has high mechanical strength.

High voltage pin type insulator.

The pin type insulator. Therefore in this types of insulators in transmission lines insulator is not economical beyond 33 kv. Pin insulators are the earliest developed overhead insulator but are still commonly used in power networks up to 33 kv system. The invention of suspension type insulators made high voltage power transmission possible.

Suspension insulators as it is already mentioned above pin insulators become too bulky an uneconomical beyond 33 kv. Cauvet on 25 july 1865 for a process to produce insulators with a threaded pinhole. The flashover voltage for the moist and dirty surface is less than that for the clean and dry surfaces. Jiangsu jinsanli power equipment industrial co ltd.

Pin type insulator can be one part two parts or three parts type depending upon application voltage. Specification of pin insulator. All victor pin types are rus accepted where a specific rus classification exists. It has high mechanical strength.

An insulator that is used to isolate a wire from physical support such as a pin on a utility pole or tower is known as pin type insulator. In a 11 kv system we generally use one part type insulator where whole pin insulator is one piece of properly shaped porcelain or glass. Pin insulator can sustain up to 11kv voltage capacity. The total wet arcing distance is a b c.

Victor manufacturers three classes of pin type insulators. Is best high voltage insulator pin type insulator and suspension type insulator supplier we has good quality products service from china. Pin type insulators still have threaded pinholes. It is represented by a b c.

What is the pin type insulator. Utility patent number 48 906 was granted to louis a. The total dry arcing distance is the sum of all the direct distances through the air. It is desirable to have high value of safety factor so that a flash over takes place before the insulator gets punctured.

The cost of pin type insulator increases rapidly as the working voltage is increased. Whether you need pin type distribution insulators or high voltage station post insulators we have you covered. For pin type insulators the value of safety factor is about 10. Advantages of pin insulator.

It can be connected with horizontal as well as vertical position. This type of insulator is used in the high voltage overhead. We offer our high voltage insulators only after a rigorous quality testing and audit system ensuring each item reliably serves our customers. The insulators like pin strain and shackle are applicable in medium to high voltage systems whereas shackle and stay are applicable in low voltage applications.
