Abstract
An anode assembly is disclosed for use in a cathodic protection system. The anode assembly includes an elongated housing, an electrical cable, an anode, and electrically conductive backfill. The housing has a leading end and a trailing end through which the electrical cable extends. The anode is located within the housing and is in the form of a plurality of electrically conductive segments which are spaced apart from each other and which are electrically connected to the electrical cable at respective electrically conductive joints. The backfill surrounds the anode and cable within the housing.
Claims19
An anode assembly for use in a cathodic protection system, said anode assembly having a leading end and a trailing end and comprising:
- a) a continuous electrical cable extending the length of said anode assembly between said leading end and said trailing end, said continuous electrical cable having an electrically insulating covering thereon, said electrically insulating covering having at least first, second, third and fourth sequentially spaced openings therein, whereupon each of said openings exposes a respective sequential portion of said electrical cable thereat;
- and
- b) an anode comprising at least a first electrically conductive anode segments and a second electrically conductive anode segment, said first electrically conductive anode segment being electrically connected in parallel across said first and second sequentially spaced openings, said second electrically conductive anode segment being electrically connected in parallel across said third and fourth sequentially spaced openings;
- said first electrically conductive anode segment being spaced from said second electrically conductive anode segment by a gap but being electrically interconnected to each other indirectly by a portion of said continuous electrical cable extending between said second and said third sequentially spaced openings.
