Cap and pin type insulator.
Cap and pin type insulator consists of porcelain units iron cap and insulator end fittings can be made from porcelain and polymer materials.
Most cap and pin insulators were installed many years ago.
It should be used with the spindle.
The construction of the pin type insulator is simple and requires less maintenance.
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.
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.
The pin of the insulator damaged the insulator thread.
As they age and break they need replacing.
The voltage rating is limited i e up to 36kv.
Cap and pin insulator insulators insulator insulator 22kv insulators 22kv insulators 25kv insulator post pin polymer insulator.
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.
It can be used vertically as well as horizontally.
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.
It is only used in the distribution line.
Galvanized ductile iron cap.
The detail explanation of the cap and pin and hewlett type insulator are explained below.
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.
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.
Disadvantages of pin 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.
Multifunctional high tensile strength cast iron disc caps cap and pin insulator metal fitting.
