The Major Differences Between Pin Insulators and Post Insulators

Electrical insulators vary in terms of shape, size, and function. Among numerous insulators, pin Insulators and post insulators are two notable types. Both these insulators are very different from each other. But how? Let’s find the answers by discussing the major differences between pin and post insulators. Buy any of these insulators from only a renowned manufacturers of cylindrical support insulators for ESP.

Pin Insulators

The most common type of insulators is pin insulators. Pin Insulators contain a single-body glass or porcelain body with a threaded metal pin at the bottom. It is to secure the cross-arm and other supporting structures. These insulators are ideal for voltages up to 33KV. The most intriguing features of these insulators are easy installation, simplicity, and cost-effectiveness.

Post Insulators

The next category of insulators is post-insulators. These insulators are used in electrical stations and substations. They have excellent mechanical strength and high flashover voltage capacity, making them ideal for conductors that require insulation from the supporting structure. Post-insulators are used only in high-voltage applications ranging from 11KV to 10000KV.

The Differences:

• The very first difference between these two insulators is their profile. Pin insulators generally have a small profile, while post insulators include a large profile on the other side.
• The pin insulators are meant to reduce the stress on the conductor. The post insulators offer support to the conductors.
• The pin insulators include two or three pins. While in the other hand, post insulators include four or more pins.
• Another great difference between the pin insulators and post insulators is the placement. Pin insulators are placed on the cross-arm of the pole of power distribution lines. On the other side, post insulators are positioned to vertical lines.
• Most of the pin insulators are cost-effective and easy to install. Post-insulators, on the other side, are expensive and hard to install.
• When it is a matter of durability, pin insulators are always better than the post insulators. Always buy these insulators from reputable insulator manufacturers in India.
• Another great feature of pin insulators is their corrosion resistance. On the other side, post-insulators are resistant to harsh weather conditions.
