Definition of Polymer Insulators

The polymer insulator is a special insulation control, which can support the wires and prevent the current from returning to the ground in the overhead transmission line. The main function of early composite insulators was to increase the creepage distance. The composite insulator is composed of an umbrella cover, a core rod, and hardware at both ends.

Features of ZMS's Polymer Insulators

1. Lightweight.

2. Good stain resistance.

3. Small daily maintenance.

4. Widely used in high-voltage lines.

5. Easy to install.

Application of ZMS's Polymer Insulators

1. It can be used in high-altitude areas, where the transmission lines in this area serve as insulation and stable conductors.

2. It can be used in harsh environments. The performance of composite insulators is very excellent and can adapt to a variety of harsh natural environments.

3. The mechanical properties of composite insulators are very good, which can be applied to the scenes with higher requirements for mechanical properties.
