Silicone Rubber Composite Insulator for Power Line

1. Gold accessories are the transmission parts of mechanical load of synthetic insulators. They are assembled together with mandels to form the connection parts of synthetic insulators.The structure affects the strength of mandrel and the mechanical properties of insulator.

2. The umbrella skirt jacket is the outer insulation part of the synthetic insulator. Its function is to make the synthetic insulator have high enough outer insulation performance against wet flashover and pollution flashover, and to protect the manrod from atmospheric erosion.

3. Mandels are the bearing part of the mechanical load of composite insulators and the main part of internal insulation.

4. Part of the bonding layer is to use adhesive glue to complete the connection between the sheath and mandrel;The other part uses glue to connect the skirt.The quality of bonding is directly related to the level of internal insulation.

The umbrella cover material uses high-temperature silicone rubber throughout. This material has better water repellency and aging resistance than earlier materials such as epoxy resin, EPDM rubber, and room temperature vulcanizing silicone rubber. Therefore, it has strong resistance to flashover. Currently, the rubber compound formulation has been further optimized. The aluminum hydroxide powder in the compound has undergone activation treatment, which greatly improves its water repellency. High-end products use silicone rubber produced from imported D4 monomer raw materials, further improving its anti-aging properties.

Shed Structure

Early sheds structures were of equal diameter. Later, alternating-size umbrellas were developed, improving flashover characteristics. Now, sheds with large-small-medium-small-large, large-small-small-large, and large-small-small-medium-small-small-large structures have been developed. Because these shed structures have a large spacing between the large sheds, the flashover voltage gradient per unit height is higher, improving resistance to ice flashover. The zigzag distribution of the large, medium, and small sheds in these structures effectively suppresses DC discharge, thus correspondingly increasing the flashover voltage.
