Cap And Pin Type Insulator

Disadvantages of pin insulator.

Cap and pin type insulator.

Cap and pin insulator insulators insulator insulator 22kv insulators 22kv insulators 25kv insulator post pin polymer insulator. 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. 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. High voltage 24 kv silicone rubber polymer.

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 pin of the insulator damaged the insulator thread. The construction of the pin type insulator is simple and requires less maintenance. The features of cap and pin type insulator.

It can be used vertically as well as horizontally. Cap and pin type insulator consists of porcelain units iron cap and insulator end fittings can be made from porcelain and polymer materials. As they age and break they need replacing. 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.

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 is only used in the distribution line. Most cap and pin insulators were installed many years ago. It should be used with the spindle.

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. The detail explanation of the cap and pin and hewlett type insulator are explained below. 100 140kv cap and pin type toughened glass insulator bonle has the advanced production equipment professional specialized technical force and rich production experience and complete control equipment. Multifunctional high tensile strength cast iron disc caps cap and pin insulator metal fitting.

The voltage rating is limited i e up to 36kv.
