Abstract
Disclosed is a composite insulator (1) having a core (2), in particular made of a fiber-reinforced duromer, and a protective layer (8) which surrounds the core (2) and is made in particular of an insulating elastomer. In some sections, especially on the bottom side of screens (4), the protective layer (8) specifically includes particles (7) that influence the field of the insulator (1).
Claims14
A composite insulator comprising:
- a core of a fiber-reinforced thermoset;
- and
- a plurality of sheds positioned along the core to extend the creepage distance, wherein:
- a first subset of the sheds comprises field-influencing particles influencing the field of the insulator;
- a second subset of the sheds does not comprise the field-influencing particles;
- the first subset are one or more sheds positioned along one end of the core;
- the second subset are one or more sheds positioned along the other end of the core;
- and
- at least one shed of the first subset of sheds comprises (i) field-influencing particles at an underside of the at least one shed and (ii) no field-influencing particles at an upper side of the at least one shed.
