Product Description
Product Overview
Light Gray 5kV ANSI A20-1 Porcelain Standoff Insulators provide reliable electrical insulation for distribution and transmission applications. Manufactured from high-quality non-porous electrical porcelain, these insulators deliver long service life and cost-effective performance in various industrial settings.
Technical Specifications
| ANSI Class | Rated Voltage (kV) | Height (mm) | Cantilever Strength (kN) | Tensile Strength (kN) | Torsion Strength (N.m) | Compression Strength (kN) | Power Frequency Withstand Voltage (kV) | Impulse Withstand Voltage (kV) |
|---|---|---|---|---|---|---|---|---|
| A20-1 | 5 | 89 | 4.5 | 8.9 | 284 | 89.2 | 19 | 60 |
Construction Features
Hardware Components
Our insulators feature externally attached caps or bases with a highly engineered cementing system that transfers load uniformly from the hardware into the porcelain body.
Porcelain Body
Each insulator body is manufactured from premium clay raw materials processed to achieve full vitrification. The glazed surface enhances strength, improves appearance, and facilitates cleaning.
Available Options
Available in either chocolate brown or Munsell gray glaze finishes. All caps and flanges are ferrous materials with hot-dip galvanized coating, featuring properly tapped thread holes.
Applications
Post insulators provide rigid support for conducting cables while offering maximum resistance to damage from electrical or mechanical events. Horizontal and gain-base line post insulators are commonly used to eliminate the need for cross-arm installation on poles.
Competitive Advantages
- Reasonable insulation structure with high reliability of inter-turn insulation
- Stainless steel flange with low magnetic inductivity and high resistivity
- Convenient transportation and flexible installation options
- Low power loss and minimal temperature rise
- High mechanical strength with excellent weather resistance
- Outstanding crack resistance properties
- Low thermal expansion coefficient for dimensional stability
