Post insulators are a type of high-voltage insulator. Their designs resemble those of ANSI, IEC, and other standards. A power system of up to 1100 KV can use these insulators.
Most solid core insulator manufacturers use composite materials in their production. Post-insulators are so popular because of their extraordinary mechanical features. In this step-by-step guide to post insulators, we’ll discuss some notable facts.
Definition of Post Insulators
Post-insulators are ideal for high-voltage applications. In transmission line applications, we know these insulators as long post-insulators. Their flanges are narrow and sharp. Most post-insulators use ceramic materials as a prime ingredient.
Types of Post Insulators
Based on the design, there are 5 types of line post insulators. Let’s learn some facts about them.
• Tie Top-line Post Insulators
The top-line post insulators contain core rod F neckline posts. Hence, they are replaceable and like pin insulators.
• Vertical Clamp Top-line Post Insulators
Vertical clamp top-line post insulators have a clamp post and stud base. These insulators are important for installing on the top of a pole.
• Horizontal Clamp Top-line Post Insulators
Horizontal clamp top-line post insulators have a vertical clamp top-line post. You can notice the post on the side of a utility pole.
• Horizontal Line Post Insulators
Horizontal line post insulators have a gain base and clamp top. These two are visible on the side of the pole.
• Brace Post Insulators
Brace post insulators are a combination of horizontal line posts and suspension insulators. These insulators include silicone rubbers.
These are some of the most common types of post-line insulators. We at Reliance Potteries can offer you a variety of industrial-grade insulators. As a top solid core insulator manufacturer, our products can surpass your needs. Get in touch with our experts.
Features of Post Insulators
Post-insulators are the first choice for transmission lines. But why? Below are the reasons behind it.
High Mechanical Strength
Post-insulators are famous for their high mechanical strength. Insulators need to face torsion, compression, and bending forces every day. Hence, the insulators must have the capacity to withstand those factors. Otherwise, they can collapse or need replacement.
Puncture-Proof & Solid
Insulators are likely to encounter factors like rain, pollution and other extreme situations. So they can face damages like punctures. But, post-insulators are solid in structure and can resist damage.
Strong
Most post-line insulators include aluminium oxide and ceramics, which have high insulating properties. Porcelain is another component that makes these insulators strong.
As a leading drive insulator manufacturer, we only use premium raw materials. It ensures that all our products meet industry standards.
Flexible Creepage Distance
The post insulators include a reasonable creepage distance. Why creepage distance is so important? Because they keep the integrity of the insulation path safe. This creepage distance prevents tracking.
