Product Description

Specification

Product Description:
The 33kV Silicone Rubber Pin Insulator (Post Type) is a high-performance polymer insulator designed for distribution lines, pole-mounted transformers, and substation applications. It features a fiberglass-reinforced epoxy (FRP) core with a high-grade silicone rubber housing, providing superior pollution resistance, mechanical strength, and durability compared to traditional porcelain or glass insulators.

Key Features:

- Material & Construction:

  Core: High-strength FRP (Fiberglass Reinforced Polymer) for excellent load-bearing capacity.
  Housing: HTV (High-Temperature Vulcanized) Silicone Rubber – hydrophobic, UV-resistant, and self-cleaning.
  Mounting Type: Post insulator design (vertical or horizontal mounting).
- Electrical Performance:

  Rated Voltage: 33kV (Um = 36kV)
  Power Frequency Withstand Voltage: ≥70kV (dry), ≥50kV (wet)
  Impulse Withstand Voltage: ≥170kV (1.2/50µs)
  Creepage Distance: ≥600mm (optimized for heavy pollution areas)
- Mechanical Performance:

  Mechanical Load Capacity: ≥12kN (tensile & compressive strength)
  Cantilever Strength: ≥8kN (for side-load applications)
  Operating Temperature: -40°C to +80°C
- Environmental Resistance:

  Pollution Class IV (suitable for coastal, industrial, and desert areas)
  Anti-tracking & Erosion Resistance (IEC 60587 compliant)
  Lightweight & Vandalism-proof (no risk of shattering like porcelain)
- Standards Compliance:

  IEC 61466 (Composite insulators for overhead lines)
  ANSI C29.11 (Composite suspension insulators)
  GB/T 20142 (China standard for polymer insulators)

Applications:
- 33kV overhead distribution lines (wooden & concrete poles)
- Pole-mounted transformers & switchgear

- Substation bus supports & disconnect switches
- Railway electrification & renewable energy projects
