Polymer Pin Insulator

Polymer pin insulator applications

Polymer pin insulators are used in high voltage power lines to support conductors and insulate them from the ground. composite insulators are used under 35kV distribution lines. Due to the many advantages of this insulator, it is now increasingly used in many countries and regions to replace porcelain or ceramic insulators.

Polymer pin insulator composition

1、The core adopts epoxide reinforced glass fiber ties, which has good insulating ability, light quality and high strength.
2、The outer insulating layer is silicon rubber, which is pressed by high temperature integration and has the characteristics of good sealing, high dustproof grade and maintenance-free.
3、Metal connection is made by pressing process, which makes the insulator smaller and no damage to the core rod. Good sealing and very easy to install.

Features of polymer pin insulator

1、The lower surface and groove of the umbrella skirt are easy to clean. The shape of the umbrella skirt is basically symmetrical and there is no obvious warpage.
2. Composite pin insulator is suitable for both vertical and horizontal applications. It is suitable for both bare and protected conductors.
3. The bottom metal end joint of this composite insulator can be suitable for mounting on steel cross arms or wooden cross arms.
4. The top and side slots can be designed to accept conductor sizes within the customer's requirements.
5. The final color of the insulator shell should be red or gray

How to use Polymer Pin Insulator

Polymer pin insulators are designed to be used in electrical power systems to support and insulate power lines from the poles or towers. Here are the steps to use a polymer pin insulator:

1. Ensure that the insulator is the appropriate type and size for the voltage and current rating of the power line.

2. Inspect the insulator for any damage or defects before installation. Check for cracks, chips, or other signs of wear and tear that could compromise the insulator's integrity.

3. Clean the pin and the insulator thoroughly to ensure that there is no dust, dirt, or debris that could affect the insulator's performance.

4. Insert the pin into the insulator's center hole, making sure that it is secure and tightly fastened.

5. Mount the insulator on the pole or tower, using the appropriate hardware and brackets. Make sure that the insulator is securely attached and that the power line is properly positioned.

6. Ensure that the insulator is properly aligned with the other insulators in the power line to maintain the correct electrical clearance and reduce the risk of flashover.

7. Regularly inspect the insulator for signs of damage or wear and tear, and replace it if necessary to maintain the safety and reliability of the power system.
