What Are The Regulations For Installing Composite Insulators?

The installation specifications for composite insulators are as follows:

Electrical Distance: Meets GB/T 26218 standard; minimum air gap for 110kV lines ≥ 1.0m.

Mechanical Strength: Safety factor ≥ 2.5; must match conductor load.

Installation Angle: Tilt angle ≤ 30°; avoid water accumulation.

Connection Tightening: Bolt torque as per manufacturer's requirements (e.g., 40~60 N·m); anti-loosening measures in place.

Cleaning and Inspection: Remove surface dirt before installation; ensure no cracks or damage.
