Abstract
An insulator that has particular application for enclosing a switching device, such as a vacuum interrupter. The insulator includes a body having a top portion and a bottom portion, and a plurality of ring-shaped sheds extending from the body between the top portion and the bottom portion. The sheds are asymmetrical in an axial direction such that an axial dimension of the sheds at one side towards the front of the switching device is shorter than an axial dimension of the sheds at an opposite side towards the rear of the switching device. The axial dimension of the sheds uniformly increases from the one side to the opposite side.

An insulator comprising:
- a body having a top portion and a bottom portion;
- and
- a plurality of ring-shaped sheds extending from the body between the top portion and the bottom portion, the sheds being asymmetric in an axial direction such that an axial dimension of the sheds at one side is shorter than an axial dimension of the sheds at an opposite side.
An insulator comprising:
- a body having a top portion and a bottom portion, the body including a plurality of equally spaced indentations formed between the top portion and the bottom portion;
- and
- a plurality of ring-shaped sheds extending from the body between the top portion and the indentations, the sheds being asymmetric in an axial direction such that an axial dimension of the sheds at one side is shorter than an axial dimension of the sheds at an opposite side, wherein the axial dimension of the sheds uniformly increases from the one side to the opposite side.
A switching device comprising:
- a switch having a front side and a rear side;
- and
- an outer insulator formed over the switch, the insulator including a body having a top portion and a bottom portion, the insulator further including a plurality of ring-shaped sheds extending from the body between the top portion and the bottom portion, the sheds being asymmetric in an axial direction such that an axial dimension of the sheds at the front side is shorter than an axial dimension of the sheds at the rear side.
