Composite Insulator for T/L (Post Type)

Product Feature

• Application Scenarios

  Suitable for overhead lines of 230kV and below, used to support line conductors such as line terminations, angles, and tangents. Can be installed on steel towers or wooden poles, compatible with bare or covered conductors.

• Core Components

  Includes E-CR fiber reinforced polymer rod, metal fittings, and HTV silicone rubber housing; glass material has electrical and chemical stability.

• Key Parameters

  Diverse cantilever loads (8kN-20kN, etc.); lightning impulse withstand voltage, creepage distance, etc., match voltage levels (69kV-220kV), with corresponding dry arc distance and insulation performance.
• Technical Advantages

  Inherits HTV silicone rubber patented technology and integral molding process, with strong hydrophobicity, reduced leakage current, lower cleaning frequency, and saved maintenance cost.
