Standard Pole Line Hardware Galvanized Pole Top Pin | Durable Hot-Dip Galvanized Insulator Support

Standard Pole Line Hardware Galvanized Pole Top Pin

The Standard Pole Line Hardware Galvanized Pole Top Pin is engineered for supporting insulators in overhead power distribution systems and transmission networks. Manufactured from high-strength forged steel and coated with ASTM A153 hot-dip galvanization, this Galvanized Pole Top Pin provides long-term corrosion resistance, mechanical durability, and stable load-bearing performance under tension, wind pressure, vibration, and continuous outdoor exposure. With standardized threading and universal insulator compatibility, the Galvanized Pole Top Pin ensures reliable installation and alignment of porcelain or composite insulators in 11kV–69kV power line applications.

Product Advantages:

1. Heavy-duty forged steel construction for long service life

2. ASTM A153 hot-dip galvanized coating ensures anti-rust and weather resistance

3. Compatible with multiple insulator types and line configurations

4. High load-bearing capability for tension and suspension applications

5.Simple installation with standard mounting hole alignment

Application Scenarios & How to Use:

The Galvanized Pole Top Pin is widely applied in:

1. Overhead Distribution Systems (11–38kV)

Installed on pole crossarms to secure insulators for primary conductors.

2. Transmission Line Towers (Up to 69kV)

Used to mount top-mounted pin insulators for tension and suspension lines.

3. Rural Electrification and Utility Upgrades

Ideal for long-distance feeder extensions with harsh environments.

4. Renewable Grid Integration (Solar/Wind)

Stabilizes conductor support in new or hybrid networks.

Installation Method：
