There is described 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 fibre-reinforced polymer in the annular cavity; and a layer of helical wound fibre-reinforced polymer extending over the first annular projection, the annular cavity and the second annular projection. The layer of circumferentially wound fibre provides additional pressure resistance to the joint as it cannot expand under radial pressure and is therefore strong against radial loads, Such an electrical isolator with a layer of hoop fibre is better adapted to the high pressures of hydraulic systems. The layer of helical wound fibre provided radially outwardly of the circumferential fibre provides axial strength, providing axial compression on two projections and thus holds the two fluid-carrying members and the resistive, semi-conductive or non-conductive component all tightly together.
