COMPOSITE LINE POST INSULATOR

Product Description：

The 72kV Composite Line Post Insulator is engineered for high voltage transmission systems requiring exceptional insulation, pollution resistance, and outdoor durability. Manufactured with high-quality silicone rubber and a fiberglass-reinforced rod, this 72kV composite line post insulator provides superior electrical performance, lightweight construction, and excellent resistance to tracking, UV exposure, and severe weather conditions. It ensures stable line support and reliable insulation in areas affected by heavy pollution, salt fog, industrial emissions, and wet environments.

Product Advantages：

1. Excellent pollution resistance for industrial and coastal regions.

2. High mechanical strength with fiberglass rod reinforcement.

3. Silicone rubber housing provides anti-tracking and UV resistance.

4. Lightweight design reduces tower load and installation effort.

5. Strong weatherproof performance under rain, snow, salt fog, and humidity.

6. Suitable for both new transmission projects and system upgrades.
   

Application Scenarios:

1. High Voltage Transmission Lines (72kV Systems)

• Used as a support and insulation component on transmission towers.

• Install the composite line post insulator onto the crossarm using bolts, then fix the conductor with clamps.

2. Heavy Pollution or Industrial Zones

• Ideal for areas exposed to dust, chemical emissions, industrial smoke.

• Ensure the insulator is upright and properly torqued during installation to prevent contamination accumulation.

3. Coastal or Salt-Fog Environments

• The silicone rubber housing resists salt corrosion and electrical tracking.

• Mount the insulator on galvanized steel or alloy crossarms to prevent galvanic issues.

4. Mountainous or High-Wind Regions

• Offers high mechanical bending strength to withstand line tension and wind load.

• Secure conductors using tension clamps or suspension fittings for optimal performance.

Safety & Quality Assurance：

Every 72kV Composite Line Post Insulator is subject to mechanical bending tests, hydrophobicity testing, tracking & erosion tests, salt fog resistance testing, and electrical routine tests. All products comply with IEC, ANSI, and national high-voltage insulation standards.
