Cap And Pin Type Insulator

As they age and break they need replacing.

Cap and pin type insulator.

High voltage 24 kv silicone rubber polymer. The pin of the insulator damaged the insulator thread. Cap and pin insulator insulators insulator insulator 22kv insulators 22kv insulators 25kv insulator post pin polymer insulator. 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 features of cap and pin type insulator. It should be used with the spindle. The detail explanation of the cap and pin and hewlett type insulator are explained below. Cap and pin type suspension insulators 550kn dc suspension porcelain insulator xzp 550 u550b 420kn dc suspension porcelain insulator xzsp1 420 u420b 300kn dc suspension porcelain insulator xzwp 300 u300b.

It can be used vertically as well as horizontally. Most cap and pin insulators were installed many years ago. And cap insulators failures of pedestal type pin and cap insulators the problem of failure of pedestal type insulators first appeared on a 34 5 kv bus at a reclamation substation in 1962. Multifunctional high tensile strength cast iron disc caps cap and pin insulator metal fitting.

Since that time similar failures have occurred on 12 47 kv 34 5 kv 41 8 kv and 69 kv bus installations at many other locations. The background of the problem and the design concepts which resulted in this new product line may be found in victor s product brochure cap and pin replacement insulators which is available from our agents or directly from the factory. These cap and pin replacement insulators are of the correct height bolt circle electrical characteristics and mounting configuration to permit direct substitution for the cap and pin or cap and pin stack. Cap and pin type insulator consists of porcelain units iron cap and insulator end fittings can be made from porcelain and polymer materials.

The voltage rating is limited i e up to 36kv. 1 cap and pin type insulator a galvanised cast iron or forged steel cap and a galvanised forged steel pin are connected to porcelain in the cap and pin type construction the unit is joined either by ball and socket or clevis pin connections. Since they are different heights from normal station posts mps has developed a variety of these replacement silicone posts that are the exact same height as the porcelain. Galvanized ductile iron cap.

Disadvantages of pin insulator.
