Epoxy Rods

Epoxy rods can be divided into two categories according to their classification: 1. Epoxy glass fiber rod, also known as pull rod, is generally used for main technical indicators of arrester or insulator core rod:

Firstly, let us learn something about epoxy fiberglass rod.

Properties of epoxy glass fiber rod

1. Shear strength is more than 32Mpa

2. Dielectric constant 3-6

3. Dielectric loss factor (50Hz) greater than or equal to 0.02

4. Volume resistivity: the normal value is greater than or equal to the 11th power of 1.0 * 10, and the immersion value is greater than or equal to the 9th power of 1.0 * 10

5. Insulation resistance in parallel direction 1. It is greater than or equal to the 11th power of 1.0 * 10 under normal condition, and it is greater than or equal to the 9th power of 1.0 * 10 under water immersion condition

6. Surface withstand voltage (withstand voltage in air for 1 minute, spacing 30mm) 14 kV

7. Vertical layer withstand voltage (withstand voltage in 90 + - 2 ℃ transformer oil for 5 minutes) 18-20 kV

8. Parallel layer direction withstand voltage (withstand voltage in 90 + - 2 ℃ transformer oil for 5 minutes, with an interval of 25mm)

More than 25 kV

Over 50 kV

Over 75 kV

9. The insulation resistance of green water epoxy insulation rod is more than or equal to the 4th power of 5 * 10

10. Power frequency withstand voltage: distance between oil chamber of on load tap changer and ground (withstand voltage in transformer oil, 100mm). 5 minutes) phase to phase distance (according to customer's technical requirements) greater than 85 kV

Models and specifications include:

Epoxy Round bar: Φ 18 Φ 24 Φ 26 Φ 28 Φ 30 Φ 32 Φ 34 Φ 36 Φ 40 Φ 45 Φ 50 Φ 53 Φ 55 Φ 60 Φ 63 Φ 70 Φ 80 Φ 90

Epoxy square bar: 10 * 24 10 * 22 10 * 30 20 * 30 20 * 20

The density is about 2.2g/cm3, and the length can be customized according to customers' needs
