Overhead Transmission Line Polymer Composite Suspension Tension Insulator

Overhead Transmission Line Polymer Composite Suspension Tension Insulator

Structure
Composite insulator is made of Fibre Glass Core Rod, Silicone Rubber Shed and Metal Fitting. The silicone rubber shed adopt the whole pressure technique, which solves the main problem of interface electric spark puncture. Connection the fibreglass rod with metal fittings adopts advanced crimping technology. Galvanized end fittings can be anti corrosion.

Features:

1. High mechanical strength, epoxy fiber glass rod tension strength is double of normal steel, 8-10 times of porcelain materials.
2. High performance against pollution & flashover, the wet withstand voltage is 2-2.5 times of porcelain insulator at same creepage distance.
3. Good performance of hydrophobicity.
4. Small volume & Light weight, easy for transportation. Therefore, it is a new generation for electric power line.

End Fitting:
The end fittings are in accordance with IEC 61466-1 (Composite string insulator units for overhead lines with a nominal voltage greater than 1000 V – Part 1: Standard strength and end fittings). ANSI standard also available.

Composite Suspension / Tension Insulator

Main Technical Parameter (IEC 61109)

Note:

1.We can produce as per customer’s requirements.

2.Corona Ring is necessary at 220kV system and above. For application at 220kV & 230kV, one corona ring should be assembled at the end of Suspension Insulator. While application at 330kV and above, two corona rings should be assembled at both end of insulator.
