Abstract
An insulator for a cutout switch and fuse assembly used in connection with an electrical power grid, including a body including a first end and a second end, a guide connector, a conductor strip, and a tool structure is located, a pivot connector is located at the second end of the body, and a mounting connector is located on the body between the first end and the second end. In an alternative embodiment, universal connectors are located at the first end and the second end. The body is manufactured by a filament winding process.
Claims20
1) A fuse cutout assembly, comprising:
- a) a body, that has been filament wound, provided with a first end, a second end, a fuse side, and a mounting side;
- b) a mounting connector including a crimping portion and an extending portion, the crimping portion of the mounting connector includes a first crimping arm and a second crimping arm that locate the mounting connector on the body between the first end and the second end;
- c) a guiding connector including a crimping portion, a fuse accepting portion, a dome, a recess, and an out-of-round portion, wherein the guiding connector is crimped to the first end of the body;
- d) a conducting strip including a domed surface, a conducting extension, and a contact, wherein the domed surface cooperates with the recess and the conducting extension is located adjacent to the out-of-round portion of the guiding connector;
- e) a tool structure provided with a first hooking arm and a second hooking arm welded to the guiding connector;
- and
- f) a pivot connector including a crimped portion, a first trunnion holder, and a second trunnion holder, wherein the pivot connector is crimped to the second end of the body.
15) A process for manufacturing an insulator, comprising the steps of:
- a) rotating a spool on a spindle about an axis;
- b) winding a fiber around the spool to form a hoop;
- c) partitioning the hoop so that a body is formed, the body is provided with a first end, a second end, a first side wall, a second side wall, a fuse side, and a mounting side;
- d) crimping a guiding connector, a mounting connector, and a pivot connector to the body;
- and
- e) molding a housing over the body.
16) The process for manufacturing an insulator, further comprising:
- a) molding sheds on the housing.
17) The process for manufacturing an insulator, further comprising:
- a) winding the fiber to provide the hoop with an elliptical cross-sectional shape.
18) The process for manufacturing an insulator, further comprising:
- a) impregnating the fiber with an epoxy resin.
19) The process for manufacturing an insulator, wherein the fiber is a polyester.
20) A process for manufacturing an insulator body, comprising the steps of:
- a) rotating a spool on a spindle about an axis;
- b) winding a glass fiber, preimpregnated with epoxy resin, around the spool to form a hoop;
- c) exposing the hoop to UV-light;
- d) removing the hoop from the spool;
- and
- e) cutting the hoop to form two bodies.
