High Voltage Pin Type Insulator
This type of insulator is used in the high voltage overhead.
High voltage pin type insulator. Cauvet on 25 july 1865 for a process to produce insulators with a threaded pinhole. What is the pin type insulator. It is desirable to have high value of safety factor so that a flash over takes place before the insulator gets punctured. It has high mechanical strength.
The pin type insulator. All victor pin types are rus accepted where a specific rus classification exists. Specification of pin insulator. The total wet arcing distance is a b c.
The total dry arcing distance is the sum of all the direct distances through the air. It is made up of material which has high mechanical strength. Pin type insulators still have threaded pinholes. The cost of pin type insulator increases rapidly as the working voltage is increased.
Suspension insulators as it is already mentioned above pin insulators become too bulky an uneconomical beyond 33 kv. The pin types of insulators are mostly used in the distribution system. Is best high voltage insulator pin type insulator and suspension type insulator supplier we has good quality products service from china. It is represented by a b c.
For high voltages 33 kv it is a usual practice to use suspension type insulators shown in fig. The invention of suspension type insulators made high voltage power transmission possible. Therefore in this types of insulators in transmission lines insulator is not economical beyond 33 kv. 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. 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. Whether you need pin type distribution insulators or high voltage station post insulators we have you covered. Advantages of pin insulator.
Jiangsu jinsanli power equipment industrial co ltd. Victor manufacturers three classes of pin type insulators. Pin insulators are the earliest developed overhead insulator but are still commonly used in power networks up to 33 kv system. We offer our high voltage insulators only after a rigorous quality testing and audit system ensuring each item reliably serves our customers.
It can be connected with horizontal as well as vertical position. Utility patent number 48 906 was granted to louis a. For pin type insulators the value of safety factor is about 10. Pin insulator can sustain up to 11kv voltage capacity.
