Cap And Pin Type Insulator

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.

Cap and pin type insulator.

The voltage rating is limited i e up to 36kv. 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. As they age and break they need replacing. 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.

It is only used in the distribution line. Cap and pin type insulator consists of porcelain units iron cap and insulator end fittings can be made from porcelain and polymer materials. It should be used with the spindle. The pin of the insulator damaged the insulator thread.

Multifunctional high tensile strength cast iron disc caps cap and pin insulator metal fitting. Cap and pin insulator insulators insulator insulator 22kv insulators 22kv insulators 25kv insulator post pin polymer insulator. Most cap and pin insulators were installed many years ago. High voltage 24 kv silicone rubber polymer.

The features of cap and pin type insulator. The detail explanation of the cap and pin and hewlett type insulator are explained below. 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. Disadvantages of pin 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. 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. Galvanized ductile iron cap. 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.

It can be used vertically as well as horizontally.
