COMPOSITE LINE POST INSULATOR

Product Description：

The 69kV Composite Line Post Insulator is engineered for high-voltage transmission lines requiring strong mechanical support and superior insulation performance. Manufactured with a high-strength fiberglass core and hydrophobic silicone rubber housing, it provides excellent resistance to pollution, UV radiation, moisture, and electrical tracking. Its lightweight construction allows easy installation on poles, crossarms, and substation structures.

Product Advantages：

1. Hydrophobic silicone housing for outstanding pollution performance

2. High mechanical strength provided by fiberglass reinforced rod

3. Lightweight and easy to install on various transmission structures

4. Excellent resistance to UV, salt fog, moisture, and tracking

5. Long service life and low maintenance requirements

6. Reliable insulation under high electrical stress and harsh climates
   

Application Scenarios:

1. 69kV Transmission Line Structures：Installed on crossarms or pole structures to support conductors and ensure safe insulation distances between phases.

2. High-Pollution or Coastal Environments：Silicone rubber sheds maintain hydrophobicity, reducing flashover risks in salty, dusty, or industrial pollution zones.

3. Substation Bus and Support Points：Used as a rigid support insulator for 69kV busbars, switches, or terminal equipment.

4. Mountainous or High-Wind Zones：The fiberglass core withstands strong mechanical loads from wind-induced conductor tension.

5. Compact Line and Urban ：Small size and high dielectric strength make it suitable for dense city grids with limited space.
