Anti-corona Ring for ADSS

On transmission lines with voltage levels above 110kV, when ADSS optical cables are erected on the same pole, the optical cables are often at a higher spatial potential, which threatens the safe operation of the optical cables. The reason is the corona at the end of the pre-twisted wire fittings. The anti-corona ring produced by our company greatly improves the electric field condition at the end of the pre-twisted wire fittings, and can increase the corona initiation voltage by more than double.

Product Details

Anti-corona ring for ADSS is made of Al. Alloy.

1.Select the required model according to the diameter of the optical cable.

2.Each set of strain clamp is equipped with an anti-corona ring.

The ADSS optical cable erected on the same pole with the high-voltage overhead transmission line is prone to electrical corrosion at the outlet of the fittings. An anti-corona ring can be installed at the outlet of the ADSS optical cable fittings to suppress the electrical corrosion. The research results show that installing an anti-corona ring at the outlet of the ADSS optical cable fittings can improve the electric field distribution on the surface of the optical cable, and significantly inhibit the electrical corrosion of the ADSS optical cable.

Anti-corona Ring for ADSS

Type	Overall Diameter (mm)	Griping section mm	Total length mm
FYH-10	9.1-11.0	250	355
FYH-12	11.1-13.0	250	355
FYH-14	13.1-15.0	250	355
FYH-16	15.1-17.0	250	355
FYH-18	17.1-19.0	350	355

Safety Note:

It must be ensured that the extreme contact pressure under the fitting does not exceed the extrusion design limit of the ADSS optical cable. In the use of the tension value, it is necessary to ensure that the ADSS optical cable and the wire do not whip, and the load on the tower is as small as possible to avoid safety problems.
