Electrical isolator

A method of forming one or more electrical isolators, the method comprising:

• connecting a first fluid-carrying member to a second fluid-carrying member
• using a resistive, semi-conductive or non-conductive component such that the resistive, semi-conductive or non-conductive component is able to convey fluid flowing from the first fluid-carrying member to the second fluid-carrying member;
• providing interwoven first fibers and second fibers extending around the first fluid-carrying member, the second fluid-carrying member and the resistive, semi-conductive or non-conductive component, wherein:
• the first fibers extend around the first fluid-carrying member;
• the second fluid-carrying member and the resistive, semi-conductive or non-conductive component at an angle of between −30 degrees and +30 degrees to a longitudinal axis of the resistive, semi-conductive or non-conductive component;
• the first fibers extend at an angle of between −5 degrees and +5 degrees to the longitudinal axis;
• and
• the second fibers extend around the first fluid-carrying member, and the second fluid-carrying member and the resistive, semi-conductive or non-conductive component at an angle of between +60 degrees and +90 degrees to the longitudinal axis or between −60 degrees and −90 degrees to the longitudinal axis;
• adding a resin to the interwoven first fibers and second fibers;
• and
• curing resin to form a reinforcing composite material.
