Electrical isolator

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;
• and
• wherein the layer of circumferentially wound fibre-reinforced polymer extends radially outwardly to at least a radial extent of the first and second annular projections.
