Insulator Systems with Corona Suppression

A method for forming a corona suppression system on an insulator system comprising:

• providing an insulator assembly comprising:
• an end fitting defining a cavity;
• an elongated insulator including first and second opposite end portions with the first end portion received in the cavity;
• and
• a cement layer in the cavity between an outer surface of the insulator and an inner surface of the end fitting;
• fitting a mold having a bottom wall and sidewall extending upwardly from the bottom wall on the insulator with the bottom wall engaging the outer surface of the insulator and being spaced apart from the end fitting;
• and
• receiving an electrically insulating material in the mold between the sidewall and the outer surface of the insulator to form an electrically insulating layer on the cement layer that extends between the insulator and the end fitting.

An insulator system comprising:

• an insulator assembly comprising:
• an elongated insulator comprising first and second opposite end portions;
• a first end fitting at the first end portion of the first insulator, the first end fitting configured to be electrically connected with a high voltage conductor;
• a second end fitting at the second end portion of the first insulator, the second end fitting connected to a mounting structure;
• a first cement layer between the first insulator and an inner surface of the first end fitting;
• and
• a second cement layer between the first insulator and an inner surface of the second end fitting;
• and
• an annular electrically insulating layer on the first cement layer and extending between the first insulator and an outer annular edge of the first end fitting.
