Polymeric suspension insulator(suspension type insulator,Rod-Type Composite Suspension Insulator, high-voltage suspension type insulator,Silicone Rubber Suspension Insulator,High-Voltage Pin Insulator,Suspension Tension Composite Insulator)

1. Light weight and high strength: Silicone rubber and other composite insulation materials are used, the weight is only 1/5-1/3 of the traditional porcelain insulator, the transportation and installation are more convenient, and the mechanical strength can meet the needs of high-voltage lines, and it is not easy to break.
2. Excellent anti-fouling performance: the surface of silicone rubber is hydrophobic (similar to the characteristics of lotus leaves that do not touch water), which can effectively prevent dust, mist and other pollutants from adhering, reduce pollution flashover accidents (insulation breakdown caused by pollution), and is suitable for use in coastal, industrial and other heavily polluted environments.

1. Aging resistance and long service life: The composite material has strong ultraviolet resistance and ozone corrosion resistance, and is not easy to crack and age in outdoor harsh environment.
2. Stable electrical performance: high insulation resistance, low dielectric loss (energy loss of insulation materials), long-term withstand of high-voltage electric field, and the insulation performance is not easily damaged in the case of lightning, switching overvoltage, etc.

1. Mechanical suspension and fixation: The conductor in the transmission line is suspended on the cross arm of the transmission tower or tower through its own structure (such as end fittings) to bear the weight of the conductor, wind load, ice load and other mechanical forces to ensure the stability of the conductor position.
2. Electrical insulation quarantine: It uses the insulation performance of its composite insulation material (mostly silicone rubber) to isolate the live wire from the grounded iron tower/pole tower, prevent current leakage, ensure the insulation strength of the line to the ground, avoid short circuit, grounding and other faults, and ensure the safety of operation and maintenance personnel.
