Patent ID: 11346475

Abstract:
An electrical isolator comprising: a first fluid-carrying member and a second fluid-carrying member spaced apart from said first fluid-carrying member; a resistive, semi-conductive or non-conductive component located between said first and second fluid-carrying member, wherein said resistive, semi-conductive or non-conductive component is adapted to convey fluid flowing from said first fluid-carrying member to said second fluid-carrying member; wherein said first fluid-carrying member comprises a first annular projection extending radially outwardly, and said second fluid-carrying member comprises a second annular projection extending radially outwardly such that an annular cavity is formed between the first and second annular projections; wherein the electrical isolator further comprises: a layer of circumferentially wound fiber-reinforced polymer in the annular cavity; and a layer of helical wound fiber-reinforced polymer extending over the first annular projection, the annular cavity and the second annular projection.
