High Amperage Surge Arrestors

A 600 A (amp) T-body elbow arrestor, comprising:

• an electrically shielded elbow body having a first longitudinally extending portion and a second longitudinally extending portion, wherein the second portion extends from an intermediate section of the first portion in a generally perpendicular direction to define the T-body;
• a metal oxide varistor (MOV) arrestor block stack positioned in the second portion of the elbow body;
• an end cap assembly coupled to an end of the second portion of the elbow body displaced from the first portion, wherein the end cap assembly includes an end cap that secures the MOV arrestor block stack in the second portion and a ground connection having an end in the second portion that is electrically connected to and end of the MOV arrestor block stack and an opposite end extending from the second portion that is configured to be connected to an external ground;
• a 600 A standard shaped bushing receiving portion positioned in the first portion of the elbow body extending from the intermediate section towards a first end of the first portion of the elbow body that is configured to receive a bushing that includes a screw threaded section thereon;
• and
• an insulating plug positioned in the first portion of the elbow body extending from the intermediate section towards a second, opposite end of the first portion of the elbow body, wherein the insulating plug has an end in the intermediate section configured to be coupled to the screw threaded section of the bushing to secure the 600 A T-body elbow arrestor in an assembled condition when the 600 A T-body elbow arrestor is coupled to the bushing.
